-## Nested Tracking Deep Dive
+## Real-World Examples
+
+### Banking Service
+
+A comprehensive banking service demonstrating thresholds, argument tracking, and nested call hierarchies.
+
+```java
+public class BankService {
+    private BalanceService balanceService;
+    private UserService userService;
+    private NotificationService notificationService;
+
+    @TimerNinjaTracker(threshold = 200)
+    public void requestMoneyTransfer(int sourceUserId, int targetUserId, int amount) {
+        User sourceUser = userService.findUser(sourceUserId);
+        User targetUser = userService.findUser(targetUserId);
+        balanceService.deductAmount(sourceUser, amount);
+        balanceService.increaseAmount(targetUser, amount);
+    }
+
+    @TimerNinjaTracker(includeArgs = true, threshold = 500)
+    public void depositMoney(int userId, int amount) {
+        // Deposit logic
+    }
+
+    @TimerNinjaTracker(includeArgs = true)
+    public void payWithCard(int userId, BankCard card, int amount) {
+        User user = userService.findUser(userId);
+        // Card payment logic
+    }
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: 851ac23b-2669-4883-8c97-032b8fd2d45c =====}
+public void requestMoneyTransfer(int sourceUserId, int targetUserId, int amount) - 1037 ms ¤ [Threshold Exceed !!: 200 ms]
+   |-- public User findUser(int userId) - 105 ms
+   |-- public User findUser(int userId) - 108 ms
+   |-- public void deductAmount(User user, int amount) - 306 ms
+   |-- public void increaseAmount(User user, int amount) - 418 ms
+{====== End of trace context id: 851ac23b-2669-4883-8c97-032b8fd2d45c ======}
+```
+
+### Notification Service — Nested Tracking
+
+Demonstrates nested method tracking with multiple levels.
+
+```java
+public class NotificationService {
+
+    @TimerNinjaTracker
+    public void notify(User user) {
+        notifyViaSMS(user);
+        notifyViaEmail(user);
+    }
+
+    @TimerNinjaTracker
+    private void notifyViaSMS(User user) {
+        try { Thread.sleep(50); }
+        catch (InterruptedException e) { throw new RuntimeException(e); }
+    }
+
+    @TimerNinjaTracker
+    private void notifyViaEmail(User user) {
+        try { Thread.sleep(200); }
+        catch (InterruptedException e) { throw new RuntimeException(e); }
+    }
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: abc123... =====}
+public void notify(User user) - 258 ms
+   |-- private void notifyViaSMS(User user) - 53 ms
+   |-- private void notifyViaEmail(User user) - 205 ms
+{====== End of trace context id: abc123... ======}
+```
+
+### Loan Processing — Mixed Annotation + Block Tracking
+
+Combines `@TimerNinjaTracker` with `TimerNinjaBlock` for phased tracking within a single method.
+
+```java
+public class LoanService {
+
+    @TimerNinjaTracker(includeArgs = true, threshold = 100)
+    public void processLoanApplication(int userId, double loanAmount, int termMonths) {
+        User user = userService.findUser(userId);
+
+        TimerNinjaBlock.measure("credit score check", () -> {
+            simulateDelay(60);
+        });
+
+        TimerNinjaBlock.measure("income verification", () -> {
+            simulateDelay(80);
+        });
+
+        BlockTrackerConfig riskConfig = new BlockTrackerConfig()
+            .setTimeUnit(ChronoUnit.MILLIS)
+            .setThreshold(30);
+
+        TimerNinjaBlock.measure("risk assessment", riskConfig, () -> {
+            simulateDelay(40);
+        });
+
+        String approvalStatus = TimerNinjaBlock.measure("final approval", () -> {
+            simulateDelay(50);
+            return "APPROVED";
+        });
+    }
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: ghi789... =====}
+public void processLoanApplication(int userId, double loanAmount, int termMonths) - Args: [userId={123}, loanAmount={50000.0}, termMonths={36}] - 345 ms
+   |-- [Block] credit score check - 60 ms
+   |-- [Block] income verification - 80 ms
+   |-- [Block] risk assessment - 40 ms
+   |-- [Block] final approval - 50 ms
+{====== End of trace context id: ghi789... ======}
+```
+
+### E-commerce Order Processing
+
+```java
+@Service
+public class OrderService {
+
+    @TimerNinjaTracker
+    public Order createOrder(OrderRequest request) {
+        Order order = validateAndCreateOrder(request);
+        PaymentResult paymentResult = processPayment(order);
+        updateInventory(order);
+        sendConfirmation(order);
+        return order;
+    }
+
+    @TimerNinjaTracker(threshold = 500, includeArgs = true)
+    private PaymentResult processPayment(Order order) {
+        return paymentService.charge(
+            order.getUserId(), order.getPaymentMethod(), order.getTotalAmount()
+        );
+    }
+
+    @TimerNinjaTracker(threshold = 200)
+    private void updateInventory(Order order) {
+        order.getItems().forEach(item ->
+            inventoryService.deductStock(item.getProductId(), item.getQuantity())
+        );
+    }
+
+    @TimerNinjaTracker
+    private void sendConfirmation(Order order) {
+        notificationService.sendEmailConfirmation(order.getUserEmail(), order);
+    }
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: jkl012... =====}
+public Order createOrder(OrderRequest request) - 2150 ms
+   |-- public Order validateAndCreateOrder(OrderRequest request) - 120 ms
+   |-- public PaymentResult processPayment(Order order) - Args: [order={id=ORD-12345, ...}] - 1250 ms ¤ [Threshold Exceed !!: 500 ms]
+      |-- public PaymentResult charge(int userId, String paymentMethod, double amount) - 1180 ms
+   |-- public void updateInventory(Order order) - 450 ms
+   |-- public void sendConfirmation(Order order) - 330 ms
+{====== End of trace context id: jkl012... ======}
+```
+
+### Constructor Tracking
+
+Track constructor initialization chains to identify slow startup:
+
+```java
+public class TransportationService {
+    private ShippingService shippingService;
+
+    @TimerNinjaTracker
+    public TransportationService() {
+        this.shippingService = new ShippingService();
+    }
+}
+
+public class ShippingService {
+    @TimerNinjaTracker
+    public ShippingService() {
+        // Shipping service initialization
+    }
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: def456... =====}
+public TransportationService() - 150 ms
+   |-- public ShippingService() - 80 ms
+{====== End of trace context id: def456... ======}
+```

-### Pattern 1: Phased Processing
+### Phased Processing (ETL Pipeline)

+public void runPipeline(String dataId) {
+    RawData raw = TimerNinjaBlock.measure("extract", () -> {

+    });
+
+    TimerNinjaBlock.measure("load", () -> {

-        RawData raw = TimerNinjaBlock.measure("extract", () -> {
-            return extractor.extract(dataId);
-        });
+### Conditional Tracking
 
-        ProcessedData processed = TimerNinjaBlock.measure("transform", () -> {
-            return transformer.transform(raw);
-        });
+```java
+@TimerNinjaTracker
+public void processWithTracking(boolean enableDetailedTracking, Data data) {
+    processMain(data);
 
-        TimerNinjaBlock.measure("load", () -> {
-            loader.load(processed);
+    if (enableDetailedTracking) {
+        TimerNinjaBlock.measure("detailed validation", () -> {

-#### 2. Use Thresholds Effectively
-
-```java
-// ✅ Appropriate threshold
-@TimerNinjaTracker(threshold = 100)
-public void meaningfulOperation() {

-```
+### Avoid Circular toString()
 
-#### 3. Avoid Circular Dependencies in toString()
+When using `includeArgs = true`, ensure argument objects don't have circular `toString()` references:
 
 ```java
-// ❌ Bad - circular reference

-## Troubleshooting Complex Scenarios
+## Troubleshooting
+
+### No Output in Logs
+
+1. Check if SLF4J provider is configured (Logback, Log4j2, etc.)
+2. Verify log level is at least `INFO`
+3. Enable `System.out` for testing: `TimerNinjaConfiguration.getInstance().toggleSystemOutLog(true);`
+
+### Methods Not Being Tracked
+
+1. Verify AspectJ plugin is configured correctly
+2. Check that the dependency includes the aspect: `aspect 'io.github.thanglequoc:timer-ninja:1.3.0'`
+3. Ensure `enabled = true` (or not set) on the annotation
 
 ### Missing Nested Traces

-## Best Practices Summary
+## Best Practices
 
 ### Do ✅
 
-1. Track entry points (controllers, main methods, public services)
-2. Use appropriate thresholds based on expected performance
-3. Enable argument logging for debugging critical operations
-4. Combine annotation and block tracking for comprehensive monitoring
-5. Track external operations (API calls, database queries, file I/O)
-6. Monitor constructor chains for slow initialization
+1. **Track entry points** — controllers, main methods, public service methods
+2. **Use appropriate thresholds** — based on expected performance for each operation tier
+3. **Enable argument logging selectively** — for debugging critical operations only
+4. **Combine annotation and block tracking** — annotations for methods, blocks for phases within methods
+5. **Track external operations** — API calls, database queries, file I/O
+6. **Monitor constructor chains** — identify slow initialization
+7. **Use structured logging** — configure logback/log4j2 for Timer Ninja output
 
 ### Don't ❌
 
-1. Track every method — focus on meaningful operations
-2. Use very low thresholds — creates noise
-3. Log sensitive data with `includeArgs`
-4. Create circular `toString()` references
-5. Track simple getters/setters
-6. Forget to configure AspectJ weaving
+1. **Track every method** — focus on meaningful operations
+2. **Use very low thresholds** — creates noise in logs
+3. **Log sensitive data** with `includeArgs` — mask or exclude sensitive fields
+4. **Create circular `toString()` references** — causes infinite loops with argument logging
+5. **Track simple getters/setters** — adds unnecessary overhead
+6. **Forget to configure AspectJ weaving** — tracking won't work without it
+7. **Use in hot paths** without considering performance impact

-## Basic Method Tracking
-
-### Simple Tracking
-
-```java
-@TimerNinjaTracker
-public void processRequest() {
-    System.out.println("Processing request...");
-}
-```
-
-**Output:**
-```
-{===== Start of trace context id: abc123... =====}
-public void processRequest() - 42 ms
-{====== End of trace context id: abc123... ======}
-```
-
-### With Time Unit
-
-```java
-@TimerNinjaTracker(timeUnit = ChronoUnit.MICROS)
-public void calculateMetrics() {
-    // Precision calculation
-}
-```
-
-**Output:**
-```
-public void calculateMetrics() - 52341 µs
-```

-
-## Banking Service Example
-
-This example shows a comprehensive banking service with multiple tracking scenarios.
-
-### Money Transfer Service
-
-```java
-public class BankService {
-    private BalanceService balanceService;
-    private UserService userService;
-    private NotificationService notificationService;
-
-    public BankService() {
-        BankRecordBook masterRecordBook = BankRecordBook.getInstance();
-        this.notificationService = new NotificationService();
-        this.balanceService = new BalanceService(masterRecordBook, notificationService);
-        this.userService = new UserService(masterRecordBook);
-    }
-
-    @TimerNinjaTracker(threshold = 200)

-        User sourceUser = userService.findUser(sourceUserId);
-        User targetUser = userService.findUser(targetUserId);
-        balanceService.deductAmount(sourceUser, amount);
-        balanceService.increaseAmount(targetUser, amount);
-    }
-
-    @TimerNinjaTracker(includeArgs = true, threshold = 500)
-    public void depositMoney(int userId, int amount) {
-        // Deposit logic
-    }
-
-    @TimerNinjaTracker(includeArgs = true)

 ## Global Configuration
 
 ### Enable System.out Logging

 ```

-
-## Best Practices
-
-### Choose Appropriate Time Units
-
-- **Seconds** — For long-running operations (API calls, file I/O, batch processing)
-- **Milliseconds** — For general application logic (default)
-- **Microseconds** — For performance-critical code (algorithms, calculations)
-
-### Use Thresholds Strategically
-
-```java
-// Too low - creates noise
-@TimerNinjaTracker(threshold = 10)
-
-// Too high - miss issues
-@TimerNinjaTracker(threshold = 5000)
-
-// Balanced - catches real issues
-@TimerNinjaTracker(threshold = 200)
-```
-
-### Track Entry Points
-
-Add tracking to high-level entry points (REST controllers, main methods) to capture full execution traces:
-
-```java
-@RestController
-public class UserController {
-    @TimerNinjaTracker
-    @GetMapping("/users/{id}")
-    public User getUser(@PathVariable Long id) {
-        return userService.findById(id);
-    }
-}
-```
-
-### Don't Track Everything
-
-**Focus on:**
-- Critical business logic
-- External API calls
-- Database operations
-- File I/O operations
-
-**Avoid tracking:**
-- Simple getters/setters
-- Very fast operations (< 1ms)
-- Trivial utility methods
-
----
-
-## Troubleshooting
-
-### No Output in Logs
-
-1. Check if SLF4J provider is configured
-2. Verify log level is at least `INFO`
-3. Enable `System.out` for testing: `TimerNinjaConfiguration.getInstance().toggleSystemOutLog(true);`
-
-### Methods Not Being Tracked
-
-1. Verify AspectJ plugin is configured correctly
-2. Check that the dependency includes the aspect: `aspect 'io.github.thanglequoc:timer-ninja:1.3.0'`
-3. Ensure `enabled = true` (or not set) on the annotation

+        });
+
+        TimerNinjaBlock.measure("income verification", () -> {
+            simulateDelay(80);
+        });
+
+        BlockTrackerConfig riskConfig = new BlockTrackerConfig()
+            .setTimeUnit(ChronoUnit.MILLIS)
+            .setThreshold(30);
+
+        TimerNinjaBlock.measure("risk assessment", riskConfig, () -> {

+        });
+
+        String approvalStatus = TimerNinjaBlock.measure("final approval", () -> {
+            simulateDelay(50);
+            return "APPROVED";
+        });
+    }
+}
+```
+
+**Output:**

-### Key Points
-
-1. **Automatic Hierarchy**: Timer Ninja automatically builds the call tree
-2. **Indentation Levels**: Each nested level is indented with `|--`
-3. **Independent Thresholds**: Each method can have its own threshold
-4. **Context Sharing**: All methods in a call chain share the same trace context ID
+**Key points:**
+- **Automatic hierarchy** — Timer Ninja builds the call tree automatically
+- **Independent thresholds** — each method can have its own threshold
+- **Context sharing** — all methods in a call chain share the same trace context ID
 
 ---
 
 ## Advanced Threshold Strategies
 
-### Dynamic Thresholds Based on Input
+### Dynamic Thresholds with BlockTrackerConfig
+
+Use `BlockTrackerConfig` to set thresholds dynamically based on runtime conditions:
 
 ```java
 @Service
 public class QueryService {
-    
+
     @TimerNinjaTracker(includeArgs = true)
     public void executeQuery(String query, int expectedRows) {
-        // Use block tracking with dynamic threshold
-        int threshold = calculateThreshold(expectedRows);
-        
+        int threshold = Math.min(100 + (expectedRows / 10), 1000);
+
         BlockTrackerConfig config = new BlockTrackerConfig()
             .setThreshold(threshold)
             .setTimeUnit(ChronoUnit.MILLIS);
-        
+
         TimerNinjaBlock.measure("query execution", config, () -> {
             database.execute(query);
         });
     }
-    
-    private int calculateThreshold(int expectedRows) {
-        // More rows = higher acceptable threshold
-        return Math.min(100 + (expectedRows / 10), 1000);
-    }
-}
-```
-
-### Adaptive Thresholds in Production
-
-```java
-@Service
-public class AdaptiveTrackingService {
-    
-    private final Map<String, Integer> adaptiveThresholds = new ConcurrentHashMap<>();
-    
-    @TimerNinjaTracker(includeArgs = true)
-    public void processRequest(String operation, RequestData data) {
-        int threshold = adaptiveThresholds.getOrDefault(operation, 200);
-        
-        // Track execution
-        long startTime = System.currentTimeMillis();
-        try {
-            // Process the request
-            performOperation(operation, data);
-        } finally {
-            long duration = System.currentTimeMillis() - startTime;
-            
-            // Adjust threshold based on observed performance
-            adjustThreshold(operation, duration, threshold);
-        }
-    }
-    
-    private void adjustThreshold(String operation, long duration, int currentThreshold) {
-        if (duration > currentThreshold * 2) {
-            // Consistently slow - increase threshold
-            adaptiveThresholds.put(operation, (int) (currentThreshold * 1.5));
-        } else if (duration < currentThreshold / 2 && duration > 50) {
-            // Faster than expected - consider lowering threshold
-            adaptiveThresholds.put(operation, (int) (currentThreshold * 0.8));
-        }
-    }
 }
 ```
 
 ### Threshold Tiers
 
-```java
-@Service
-public class TieredTrackingService {
-    
-    // Fast operations
-    @TimerNinjaTracker(threshold = 50)
-    public void cacheLookup(String key) {
-        // Very fast cache access
-    }
-    
-    // Standard operations
-    @TimerNinjaTracker(threshold = 200)
-    public void databaseQuery(String query) {
-        // Standard database operation
-    }
-    
-    // Slow operations
-    @TimerNinjaTracker(threshold = 1000)
-    public void externalApiCall(String endpoint) {
-        // External API call
-    }
-    
-    // Very slow operations
-    @TimerNinjaTracker(threshold = 5000)
-    public void batchProcess(String batchId) {
-        // Batch processing
-    }
-}
-```

-## Block Tracking Patterns
-
-### Pattern 1: Phased Processing
-
-```java
-@Service
-public class DataPipelineService {
-    
-    @TimerNinjaTracker
-    public void runPipeline(String dataId) {
-        // Phase 1: Extraction
-        RawData raw = TimerNinjaBlock.measure("extract", () -> {
-            return extractor.extract(dataId);
-        });
-        
-        // Phase 2: Transformation
-        ProcessedData processed = TimerNinjaBlock.measure("transform", () -> {
-            return transformer.transform(raw);
-        });
-        
-        // Phase 3: Loading
-        TimerNinjaBlock.measure("load", () -> {
-            loader.load(processed);
-        });
-        
-        // Phase 4: Cleanup
-        TimerNinjaBlock.measure("cleanup", () -> {
-            cleanupService.cleanup(dataId);
-        });
-    }
-}
-```
-
-### Pattern 2: Conditional Tracking
+Assign different thresholds based on expected operation speed:
 
 ```java
-@Service
-public class ConditionalTrackingService {
-    
-    @TimerNinjaTracker
-    public void processWithTracking(boolean enableDetailedTracking, Data data) {
-        // Always track main processing
-        processMain(data);
-        
-        // Conditionally track detailed steps
-        if (enableDetailedTracking) {
-            TimerNinjaBlock.measure("detailed validation", () -> {
-                validateDetailed(data);
-            });
-            
-            TimerNinjaBlock.measure("detailed transformation", () -> {
-                transformDetailed(data);
-            });
-        } else {
-            // Fast path without detailed tracking
-            validateQuick(data);
-            transformQuick(data);
-        }
-    }

-## Performance Optimization
-
-### Minimizing Overhead
-
-Timer Ninja is designed to be lightweight, but here are tips to minimize overhead:
+## Block Tracking Patterns
 
-#### 1. Selective Tracking
+### Phased Processing (ETL Pipeline)
 
 ```java
-// ❌ Bad - tracking everything
-@TimerNinjaTracker
-public String getUserName(Long userId) {
-    return userRepository.findById(userId).getName();
-}
-
 @TimerNinjaTracker
-public String getUserEmail(Long userId) {
-    return userRepository.findById(userId).getEmail();
-}
+public void runPipeline(String dataId) {
+    RawData raw = TimerNinjaBlock.measure("extract", () -> {
+        return extractor.extract(dataId);
+    });
 
-// ✅ Good - tracking only the repository call
-public String getUserName(Long userId) {
-    return userRepository.findById(userId).getName();
-}
+    ProcessedData processed = TimerNinjaBlock.measure("transform", () -> {
+        return transformer.transform(raw);
+    });
 
-@Repository
-public class UserRepository {
-    @TimerNinjaTracker
-    public User findById(Long userId) {
-        // Database query
-    }
+    TimerNinjaBlock.measure("load", () -> {
+        loader.load(processed);
+    });
 }
 ```
 
-#### 2. Use Thresholds Effectively
+### Conditional Tracking
 
 ```java
-// ❌ Too many fast operations cluttering logs
-@TimerNinjaTracker(threshold = 1)
-public void fastOperation() {
-    // Very fast operation
-}
-
-// ✅ Appropriate threshold
-@TimerNinjaTracker(threshold = 100)
-public void meaningfulOperation() {
-    // Operation that should be reasonably fast
-}
-```
-
-#### 3. Avoid Circular Dependencies in toString()
+@TimerNinjaTracker
+public void processWithTracking(boolean enableDetailedTracking, Data data) {
+    processMain(data);
 
-```java
-// ❌ Bad - circular reference in toString()
-public class User {
-    private List<Order> orders;
-    
-    @Override
-    public String toString() {
-        return "User{orders=" + orders + "}"; // Orders contain Users
-    }
-}
+    if (enableDetailedTracking) {
+        TimerNinjaBlock.measure("detailed validation", () -> {
+            validateDetailed(data);
+        });
 
-// ✅ Good - selective toString()
-public class User {
-    private List<Order> orders;
-    
-    @Override
-    public String toString() {
-        return String.format("User{id=%d, ordersCount=%d}", id, orders.size());
+        TimerNinjaBlock.measure("detailed transformation", () -> {
+            transformDetailed(data);
+        });
     }
 }
 ```
 
-### Memory Management
-
-#### 1. Clean Up Trace Contexts
-
-Timer Ninja automatically cleans up trace contexts, but you can ensure proper cleanup:
+### Retry Logic Tracking
 
 ```java
-@Service
-public class SafeExecutionService {
-    
-    @TimerNinjaTracker
-    public void executeSafely(Task task) {
+@TimerNinjaTracker
+public Result executeWithRetry(String operation, Data data) {
+    int maxRetries = 3;
+    int attempt = 0;
+
+    while (attempt < maxRetries) {
+        attempt++;
         try {
-            task.run();
+            return TimerNinjaBlock.measure(
+                String.format("attempt %d", attempt),
+                () -> executeOperation(operation, data)
+            );
         } catch (Exception e) {
-            // Trace context is still cleaned up automatically
-            throw e;
+            if (attempt == maxRetries) {
+                throw new RuntimeException("Failed after " + maxRetries + " attempts", e);
+            }
+            TimerNinjaBlock.measure("retry delay", () -> {
+                Thread.sleep(calculateBackoff(attempt));
+            });
         }
     }
-}
-```
-
-#### 2. Large Argument Objects
-
-For large objects, avoid including them in logs:
-
-```java
-@TimerNinjaTracker // No includeArgs for large objects
-public void processLargeData(LargeDataSet dataSet) {
-    // Processing logic
-}
-
-// Or provide a summary
-@TimerNinjaTracker(includeArgs = true)
-public void processData(DataSummary summary) {
-    // Processing with summary
+    throw new IllegalStateException("Should not reach here");
 }
 ```

-## Custom Logging Strategies
+## Performance Optimization
 
-### Structured Logging
+### Selective Tracking
 
 ```java
-@Service
-public class StructuredLoggingService {
-    
-    @TimerNinjaTracker(includeArgs = true)
-    public void processRequest(Request request) {
-        // Timer Ninja provides timing
-        // Add structured logging for additional context
-        log.info("Processing request: {}", request.toStructuredLog());
-        
-        // Business logic
+// ❌ Bad — tracking thin wrappers
+@TimerNinjaTracker
+public String getUserName(Long userId) {
+    return userRepository.findById(userId).getName();
+}
+
+// ✅ Good — tracking the meaningful operation
+@Repository
+public class UserRepository {
+    @TimerNinjaTracker
+    public User findById(Long userId) {
+        // Database query
     }
 }
 ```
 
-### Conditional Argument Logging
+### Avoid Circular toString()
+
+When using `includeArgs = true`, ensure argument objects don't have circular `toString()` references:
 
 ```java
-@Service
-public class ConditionalArgLoggingService {
-    
-    @TimerNinjaTracker
-    public void processSensitiveData(SensitiveData data) {
-        // Never log sensitive data
-        // Use block tracking for phases instead
-        TimerNinjaBlock.measure("validation", () -> {
-            validateData(data);
-        });
-        
-        TimerNinjaBlock.measure("processing", () -> {
-            processData(data);
-        });
+// ❌ Bad — circular reference
+public class User {
+    private List<Order> orders;
+    @Override
+    public String toString() {
+        return "User{orders=" + orders + "}"; // Orders contain Users!
+    }
+}
+
+// ✅ Good — selective toString()
+public class User {
+    private List<Order> orders;
+    @Override
+    public String toString() {
+        return String.format("User{id=%d, ordersCount=%d}", id, orders.size());

-## Troubleshooting Complex Scenarios
-
-### Issue 1: Missing Nested Traces
+## Troubleshooting
 
-**Problem:** Nested method calls not appearing in traces.
+### No Output in Logs
 
-**Solution:**
+1. Check if SLF4J provider is configured (Logback, Log4j2, etc.)
+2. Verify log level is at least `INFO`
+3. Enable `System.out` for testing: `TimerNinjaConfiguration.getInstance().toggleSystemOutLog(true);`
 
-1. Verify annotations are present on nested methods
-```java
-@TimerNinjaTracker
-public void parent() {
-    child(); // Must also have @TimerNinjaTracker
-}
-
-@TimerNinjaTracker
-public void child() {
-    // Child logic
-}
-```
-
-2. Check if methods are private/internal
-```java
-// Public/package-private methods are tracked
-// Private methods are also tracked if annotated
-```
-
-3. Verify AspectJ weaving is working correctly
-```groovy
-// Ensure aspect dependency is included
-aspect 'io.github.thanglequoc:timer-ninja:1.2.0'
-```
-
-### Issue 2: Performance Degradation
-
-**Problem:** Timer Ninja causing noticeable performance impact.
-
-**Solution:**
-
-1. Reduce tracking overhead
-```java
-// Remove tracking from hot paths
-// Use higher thresholds
-@TimerNinjaTracker(threshold = 500) // Instead of 100
-```
-
-2. Disable in production
-```java
-@TimerNinjaTracker(enabled = isDevelopment())
-public void debugMethod() {
-    // Only tracked in dev
-}
-```
-
-3. Use selective tracking
-```java
-// Track only entry points
-@TimerNinjaTracker
-public void processRequest() {
-    // Nested methods not tracked
-}
-```
-
-### Issue 3: Large Trace Outputs
-
-**Problem:** Trace logs are too large and cluttered.
-
-**Solution:**
+### Methods Not Being Tracked
 
-1. Use thresholds effectively
-```java
-@TimerNinjaTracker(threshold = 200)
-// Only shows methods taking > 200ms
-```
+1. Verify AspectJ plugin is configured correctly
+2. Check that the dependency includes the aspect: `aspect 'io.github.thanglequoc:timer-ninja:1.3.0'`
+3. Ensure `enabled = true` (or not set) on the annotation
 
-2. Disable argument logging
-```java
-@TimerNinjaTracker(includeArgs = false) // Default
-// Or selectively enable
-@TimerNinjaTracker(includeArgs = true)
-public void criticalOperation(Data data) {
-    // Only log args for critical operations
-}
-```
+### Missing Nested Traces
 
-3. Use block tracking for phases instead of individual methods
-```java
-@TimerNinjaTracker
-public void processOrder(Order order) {
-    TimerNinjaBlock.measure("validation", () -> validate(order));
-    TimerNinjaBlock.measure("processing", () -> process(order));
-    TimerNinjaBlock.measure("notification", () -> notify(order));
-}
-// One line instead of multiple method traces
-```
+1. Verify `@TimerNinjaTracker` is present on nested methods — all access levels (public, private, etc.) are tracked if annotated
+2. Verify AspectJ weaving is working: ensure the `aspect` dependency is declared
 
-### Issue 4: Thread Safety Concerns
+### Large Trace Outputs
 
-**Problem:** Tracking in multi-threaded environments.
+1. Use thresholds to filter noise: `@TimerNinjaTracker(threshold = 200)`
+2. Disable argument logging by default, enable selectively
+3. Use block tracking for phases instead of individual method tracking
 
-**Solution:**
+### Thread Safety
 
-Timer Ninja is thread-safe by design. Each thread maintains its own trace context:
+Timer Ninja is thread-safe by design. Each thread maintains its own trace context via `ThreadLocal`:

 @TimerNinjaTracker
 public void parallelProcessing() {
     ExecutorService executor = Executors.newFixedThreadPool(4);
-    
-    // Each task gets its own trace context
+
     for (int i = 0; i < 10; i++) {
         final int taskId = i;
         executor.submit(() -> {
-            processTask(taskId); // Independent trace
+            processTask(taskId); // Independent trace per thread
         });
     }
-    
     executor.shutdown();
 }
 ```

-## Best Practices Summary
+## Best Practices
 
 ### Do ✅
 
-1. **Track entry points** (controllers, main methods, public services)
-2. **Use appropriate thresholds** based on expected performance
-3. **Enable argument logging** for debugging critical operations
-4. **Combine annotation and block tracking** for comprehensive monitoring
-5. **Track external operations** (API calls, database queries, file I/O)
-6. **Monitor constructor chains** for slow initialization
-7. **Use structured logging** for additional context
-8. **Disable in production** when performance is critical
+1. **Track entry points** — controllers, main methods, public service methods
+2. **Use appropriate thresholds** — based on expected performance for each operation tier
+3. **Enable argument logging selectively** — for debugging critical operations only
+4. **Combine annotation and block tracking** — annotations for methods, blocks for phases within methods
+5. **Track external operations** — API calls, database queries, file I/O
+6. **Monitor constructor chains** — identify slow initialization
+7. **Use structured logging** — configure logback/log4j2 for Timer Ninja output
 
 ### Don't ❌
 
-1. **Track every method** - focus on meaningful operations
-2. **Use very low thresholds** - creates noise in logs
-3. **Log sensitive data** - even with `includeArgs`
-4. **Create circular toString()** - causes infinite loops
-5. **Track simple getters/setters** - adds unnecessary overhead
-6. **Ignore nested tracking** - leverage call hierarchy insights
-7. **Forget to configure AspectJ** - tracking won't work
-8. **Use in hot paths** without considering performance impact
+1. **Track every method** — focus on meaningful operations
+2. **Use very low thresholds** — creates noise in logs
+3. **Log sensitive data** with `includeArgs` — mask or exclude sensitive fields
+4. **Create circular `toString()` references** — causes infinite loops with argument logging
+5. **Track simple getters/setters** — adds unnecessary overhead
+6. **Forget to configure AspectJ weaving** — tracking won't work without it
+7. **Use in hot paths** without considering performance impact

-## Basic Method Tracking
-
-### Simple Tracking
-
-```java
-@TimerNinjaTracker
-public void processRequest() {
-    // Business logic
-    System.out.println("Processing request...");
-}
-```
-
-**Output:**
-```
-{===== Start of trace context id: abc123... =====}
-public void processRequest() - 42 ms
-{====== End of trace context id: abc123... ======}
-```
-
-### With Time Unit
-
-```java
-@TimerNinjaTracker(timeUnit = ChronoUnit.MICROS)
-public void calculateMetrics() {
-    // Precision calculation
-}
-```
-
-**Output:**
-```
-public void calculateMetrics() - 52341 µs
-```

-## Banking Service Example
-
-This example shows a comprehensive banking service with multiple tracking scenarios.
-
-### Money Transfer Service
-
-```java
-public class BankService {
-    private BalanceService balanceService;
-    private UserService userService;
-    private NotificationService notificationService;
-
-    public BankService() {
-        BankRecordBook masterRecordBook = BankRecordBook.getInstance();
-        this.notificationService = new NotificationService();
-        this.balanceService = new BalanceService(masterRecordBook, notificationService);
-        this.userService = new UserService(masterRecordBook);
-    }
-
-    /**
-     * Transfer money between users with threshold tracking
-     */
-    @TimerNinjaTracker(threshold = 200)
-    public void requestMoneyTransfer(int sourceUserId, int targetUserId, int amount) {
-        User sourceUser = userService.findUser(sourceUserId);
-        User targetUser = userService.findUser(targetUserId);
-        balanceService.deductAmount(sourceUser, amount);
-        balanceService.increaseAmount(targetUser, amount);
-    }
-
-    /**
-     * Deposit money with argument tracking
-     */
-    @TimerNinjaTracker(includeArgs = true, threshold = 500)
-    public void depositMoney(int userId, int amount) {
-        // Deposit logic
-    }
-
-    /**
-     * Payment with card - full argument tracking
-     */
-    @TimerNinjaTracker(includeArgs = true)
-    public void payWithCard(int userId, BankCard card, int amount) {
-        User user = userService.findUser(userId);
-        // Card payment logic
-    }
-}
-```
-
-### Output Example
-
-```
-{===== Start of trace context id: 851ac23b-2669-4883-8c97-032b8fd2d45c =====}
-public void requestMoneyTransfer(int sourceUserId, int targetUserId, int amount) - 1037 ms ¤ [Threshold Exceed !!: 200 ms]

-
-## Notification Service Example
-
-This example demonstrates nested method tracking with multiple levels.
-
-### Notification System
-
-```java
-public class NotificationService {
-    
-    public NotificationService() {
-        // Constructor initialization
-    }
-
-    @TimerNinjaTracker
-    public void notify(User user) {
-        // Main notification method calls sub-methods
-        notifyViaSMS(user);
-        notifyViaEmail(user);
-    }
-
-    @TimerNinjaTracker
-    private void notifyViaSMS(User user) {
-        // SMS notification logic
-        try {
-            Thread.sleep(50);
-        } catch (InterruptedException e) {
-            throw new RuntimeException(e);
-        }
-    }
-
-    @TimerNinjaTracker
-    private void notifyViaEmail(User user) {
-        // Email notification logic
-        try {
-            Thread.sleep(200);
-        } catch (InterruptedException e) {
-            throw new RuntimeException(e);
-        }
-    }
-}
-```
-
-### Output Example
-
-```
-{===== Start of trace context id: abc123... =====}
-public void notify(User user) - 258 ms
-   |-- private void notifyViaSMS(User user) - 53 ms
-   |-- private void notifyViaEmail(User user) - 205 ms
-{====== End of trace context id: abc123... ======}
-```
-

-
-## Constructor Tracking
-
-### Service Initialization Chain
-
-```java
-public class TransportationService {
-    private ShippingService shippingService;
-
-    @TimerNinjaTracker
-    public TransportationService() {
-        this.shippingService = new ShippingService();
-        // Additional initialization
-    }
-}
-
-public class ShippingService {
-    @TimerNinjaTracker
-    public ShippingService() {
-        // Shipping service initialization
-    }
-}
-```
-
-### Usage
-```java
-TransportationService service = new TransportationService();
-```
-
-### Output Example
-```
-{===== Start of trace context id: def456... =====}
-public TransportationService() - 150 ms
-   |-- public ShippingService() - 80 ms
-{====== End of trace context id: def456... ======}
-```
-
-### Disabled Constructor Tracking
-
-```java
-public class LocationService {
-    @TimerNinjaTracker(enabled = false)
-    public LocationService() {
-        // This won't be tracked
-    }
-}
-```
-
-**Output:**
-```
-There isn't any tracker enabled in the tracking context
-```
-
----
-
-## Loan Processing Example
-
-This example combines annotation-based tracking with block tracking.
-
-### Loan Application Processing
-
-```java
-public class LoanService {
-    private UserService userService;
-
-    public LoanService(UserService userService) {
-        this.userService = userService;
-    }
-
-    /**
-     * Process loan application with multi-phase tracking
-     * Combines @TimerNinjaTracker with TimerNinjaBlock for granular tracking
-     */
-    @TimerNinjaTracker(includeArgs = true, threshold = 100)
-    public void processLoanApplication(int userId, double loanAmount, int termMonths) {
-        User user = userService.findUser(userId);
-        
-        // Phase 1: Credit check - block tracking
-        TimerNinjaBlock.measure("credit score check", () -> {
-            simulateDelay(60); // Simulate credit check
-        });
-        
-        // Phase 2: Income verification - block tracking
-        TimerNinjaBlock.measure("income verification", () -> {
-            simulateDelay(80); // Simulate income verification
-        });
-        
-        // Phase 3: Risk assessment - block tracking with custom config
-        BlockTrackerConfig riskConfig = new BlockTrackerConfig()
-            .setTimeUnit(ChronoUnit.MILLIS)
-            .setThreshold(30);
-        
-        TimerNinjaBlock.measure("risk assessment", riskConfig, () -> {
-            simulateDelay(40); // Simulate risk assessment
-        });
-        
-        // Phase 4: Final approval - block tracking with return value
-        String approvalStatus = TimerNinjaBlock.measure("final approval", () -> {
-            simulateDelay(50); // Simulate approval process
-            return "APPROVED";
-        });
-    }
-    
-    private void simulateDelay(int milliseconds) {
-        try {
-            Thread.sleep(milliseconds);
-        } catch (InterruptedException e) {
-            Thread.currentThread().interrupt();
-            throw new RuntimeException("Processing interrupted", e);
-        }
-    }
-}
-```
-
-### Output Example
-
-```
-{===== Start of trace context id: ghi789... =====}
-public void processLoanApplication(int userId, double loanAmount, int termMonths) - Args: [userId={123}, loanAmount={50000.0}, termMonths={36}] - 345 ms

+# Getting Started
+
+This guide covers everything you need to install Timer Ninja and start tracking method execution time.
+
+---
+
+## Installation
+
+### Add the Timer Ninja Dependency
+
+**Gradle:**
+```groovy
+implementation group: 'io.github.thanglequoc', name: 'timer-ninja', version: '1.3.0'
+```
+
+**Maven:**
+```xml
+<dependency>
+    <groupId>io.github.thanglequoc</groupId>
+    <artifactId>timer-ninja</artifactId>
+    <version>1.3.0</version>
+    <scope>compile</scope>
+</dependency>
+```
+
+### Declare AspectJ Plugin
+
+**Gradle** — using [FreeFair AspectJ Gradle plugin](https://github.com/freefair/gradle-plugins):
+
+```groovy
+plugins {
+    id "io.freefair.aspectj.post-compile-weaving" version '9.1.0'
+}
+
+dependencies {
+    implementation group: 'io.github.thanglequoc', name: 'timer-ninja', version: '1.3.0'
+    aspect 'io.github.thanglequoc:timer-ninja:1.3.0'
+
+    // Enable this if you want to track methods in test classes
+    testAspect("io.github.thanglequoc:timer-ninja:1.3.0")
+}
+```
+
+**Maven** — using [Forked Mojo's AspectJ Plugin](https://github.com/dev-aspectj/aspectj-maven-plugin):
+
+```xml
+<plugin>
+    <groupId>dev.aspectj</groupId>
+    <artifactId>aspectj-maven-plugin</artifactId>
+    <version>1.14.1</version>
+    <dependencies>
+        <dependency>
+            <groupId>org.aspectj</groupId>
+            <artifactId>aspectjtools</artifactId>
+            <version>1.9.25</version>
+        </dependency>
+    </dependencies>
+    <configuration>
+        <complianceLevel>${java.version}</complianceLevel>

+                <goal>test-compile</goal>
+            </goals>
+        </execution>
+    </executions>
+</plugin>
+```
+
+---
+
+## Annotation-based Tracking
+
+The `@TimerNinjaTracker` annotation is the primary way to track method execution time.
+
+### Basic Usage
+
+Annotate any method to start tracking:
+
+```java
+@TimerNinjaTracker
+public void performTask() {
+    // Your business logic
+}
+```
+
+### Tracking Constructors
+
+You can also track constructor execution:
+
+```java
+@TimerNinjaTracker
+public class NotificationService {
+    public NotificationService() {
+        // Constructor logic
+    }
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: abc123... =====}
+public NotificationService() - 80 ms
+{====== End of trace context id: abc123... ======}
+```
+
+### Annotation Attributes
+
+| Attribute | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `enabled` | `boolean` | `true` | Enable or disable tracking for this method |
+| `timeUnit` | `ChronoUnit` | `MILLIS` | Time unit for measurement (SECONDS, MILLIS, MICROS) |
+| `includeArgs` | `boolean` | `false` | Include method arguments in the log trace |
+| `threshold` | `int` | `-1` | Minimum execution time required to log (in specified timeUnit) |
+
+---
+
+## Configuration Options
+
+### Enable/Disable Tracking
+
+Temporarily disable tracking for a method without removing the annotation:
+
+```java
+@TimerNinjaTracker(enabled = false)
+public void dontTrackThis() {
+    // This will NOT be tracked
+}
+```
+
+### Time Unit Selection
+
+Choose the appropriate time unit for your measurement:
+
+```java
+import java.time.temporal.ChronoUnit;
+
+@TimerNinjaTracker(timeUnit = ChronoUnit.SECONDS)
+public void longRunningOperation() { }
+
+@TimerNinjaTracker(timeUnit = ChronoUnit.MILLIS)   // default
+public void standardOperation() { }
+
+@TimerNinjaTracker(timeUnit = ChronoUnit.MICROS)
+public void preciseOperation() { }
+```
+
+### Include Method Arguments
+
+Log method arguments for better debugging context:
+
+```java
+@TimerNinjaTracker(includeArgs = true)
+public void processUser(int userId, String name, String email) {
+    // Method logic
+}
+```
+
+**Output:**
+```
+public void processUser(int userId, String name, String email) - Args: [userId={123}, name={John Doe}, email={john@example.com}] - 42 ms
+```
+
+> **Important:** Ensure your objects have proper `toString()` implementations for meaningful output.
+
+### Threshold Filtering
+
+Filter out fast methods to focus on performance issues:
+
+```java
+@TimerNinjaTracker(threshold = 500)  // Only log if execution > 500ms
+public void potentiallySlowMethod() {
+    // Method logic
+}
+```
+
+**When threshold is exceeded:**
+```
+public void potentiallySlowMethod() - 723 ms ¤ [Threshold Exceed !!: 500 ms]
+```
+
+**When below threshold:** The method is suppressed from the trace output. If all methods in a trace are below threshold, a summary is shown instead.
+
+### Combining Options
+
+```java
+@TimerNinjaTracker(includeArgs = true, threshold = 200)
+public void requestMoneyTransfer(int sourceUserId, int targetUserId, int amount) {
+    // Only logs slow transfers with full argument details
+}
+```
+
+---
+
+## Block Tracking
+
+For granular tracking within a method without extracting separate methods, use `TimerNinjaBlock`.
+
+### Basic Block Tracking
+
+```java
+public void processData() {
+    TimerNinjaBlock.measure("database query", () -> {
+        database.query("SELECT * FROM users");
+    });
+}
+```
+
+### Block with Return Value
+
+```java
+public void processData() {
+    String result = TimerNinjaBlock.measure("fetch data", () -> {
+        return api.fetchUserData();
+    });
+    System.out.println(result);
+}
+```
+
+### Block with Custom Configuration
+
+```java
+import java.time.temporal.ChronoUnit;
+
+public void processData() {
+    BlockTrackerConfig config = new BlockTrackerConfig()
+        .setTimeUnit(ChronoUnit.SECONDS)
+        .setThreshold(2);
+
+    TimerNinjaBlock.measure("long operation", config, () -> {
+        performLongRunningTask();
+    });
+}
+```
+
+### Nested Block Tracking
+
+```java
+public void complexProcess() {
+    TimerNinjaBlock.measure("overall process", () -> {
+        loadData();
+        TimerNinjaBlock.measure("data transformation", () -> {
+            transformData();
+        });
+        saveData();
+    });
+}
+```
+
+**Output:**
+```
+{===== Start of trace context id: ... =====}
+[Block] overall process - 1500 ms
+   |-- [Block] data transformation - 500 ms
+{====== End of trace context id: ... ======}
+```
+

+
+## Understanding Trace Output
+
+### Trace Structure
+
+```
+Timer Ninja trace context id: a1b2c3d4-e5f6-7890-abcd-ef1234567890
+Trace timestamp: 2023-04-03T14:27:50.322Z
+{===== Start of trace context id: a1b2c3d4-e5f6-7890-abcd-ef1234567890 =====}
+public void parentMethod() - 100 ms
+   |-- public void childMethod() - 50 ms
+   |-- public void anotherChildMethod() - 30 ms
+{====== End of trace context id: a1b2c3d4-e5f6-7890-abcd-ef1234567890 ======}
+```
+
+### Elements Explained
+
+1. **Trace Context ID** — Auto-generated UUID. All tracked methods in the same call stack share this ID.
+2. **Trace Timestamp** — When the trace context was initiated (UTC timezone).
+3. **Start/End Markers** — Delimit the trace boundaries.
+4. **Method Lines** — Each tracked method shows: signature, arguments (if enabled), execution time, threshold indicator.
+5. **Indentation (`|--`)** — Shows call hierarchy. Indented methods are called by the method above.
+
+### Summary Output
+
+When all methods in a trace are below their thresholds:
+
+```
+Timer Ninja trace context id: abc123...
+Trace timestamp: 2023-04-03T14:27:50.322Z
+All 3 tracked items within threshold. min: 5 ms, max: 45 ms, total: 50 ms
+```
+
+---
+
+## Global Configuration
+
+### Enable System.out Logging
+
+For simple console applications or quick testing:
+
+```java
+TimerNinjaConfiguration.getInstance().toggleSystemOutLog(true);
+```
+
+> Call this once at application startup. By default, Timer Ninja uses SLF4J logging.
+
+### Log Level
+
+The logger class is `io.github.thanglequoc.timerninja.TimerNinjaUtil` with default level `INFO`.
+
+To enable debug information:
+
+```xml
+<logger name="io.github.thanglequoc.timerninja.TimerNinjaThreadContext" level="DEBUG"/>
+```

-
-## Annotation-based Tracking
-
-The `@TimerNinjaTracker` annotation is the primary way to track method execution time.
-
-### Basic Usage
-
-Annotate any method or constructor to start tracking:
-
-```java
-@TimerNinjaTracker
-public void performTask() {
-    // Your business logic
-}
-```
-
-### Tracking Constructors
-
-You can also track constructor execution:
-
-```java
-@TimerNinjaTracker
-public class NotificationService {
-    public NotificationService() {
-        // Constructor logic
-    }
-}
-```
-
-**Output:**
-```
-{===== Start of trace context id: abc123... =====}
-public NotificationService() - 80 ms
-{====== End of trace context id: abc123... ======}
-```
-
-### Annotation Attributes
-
-The `@TimerNinjaTracker` annotation supports several configuration options:
-
-| Attribute | Type | Default | Description |
-|-----------|------|---------|-------------|
-| `enabled` | `boolean` | `true` | Enable or disable tracking for this method |
-| `timeUnit` | `ChronoUnit` | `MILLIS` | Time unit for measurement (SECONDS, MILLIS, MICROS) |
-| `includeArgs` | `boolean` | `false` | Include method arguments in the log trace |
-| `threshold` | `int` | `-1` | Minimum execution time required to log (in specified timeUnit) |
-
----
-
-## Configuration Options
-
-### 1. Enable/Disable Tracking
-
-Control whether a specific method is tracked:
-
-```java
-@TimerNinjaTracker(enabled = true)
-public void trackThis() {
-    // This will be tracked
-}
-
-@TimerNinjaTracker(enabled = false)
-public void dontTrackThis() {
-    // This will NOT be tracked
-}
-```
-
-**Use Case:** Temporarily disable tracking for a method without removing the annotation.
-
-### 2. Time Unit Selection
-
-Choose the appropriate time unit for your measurement needs:
-
-```java
-import java.time.temporal.ChronoUnit;
-
-@TimerNinjaTracker(timeUnit = ChronoUnit.SECONDS)
-public void longRunningOperation() {
-    // For operations taking seconds
-}
-
-@TimerNinjaTracker(timeUnit = ChronoUnit.MILLIS)
-public void standardOperation() {
-    // For operations taking milliseconds (default)
-}
-
-@TimerNinjaTracker(timeUnit = ChronoUnit.MICROS)
-public void preciseOperation() {
-    // For operations requiring microsecond precision
-}
-```
-
-**Supported Units:**
-- `ChronoUnit.SECONDS` - Seconds
-- `ChronoUnit.MILLIS` - Milliseconds (default)
-- `ChronoUnit.MICROS` - Microseconds
-
-### 3. Include Method Arguments
-
-Log method arguments for better debugging context:
-
-```java
-@TimerNinjaTracker(includeArgs = true)
-public void processUser(int userId, String name, String email) {
-    // Method logic
-}
-```
-
-**Output:**
-```
-public void processUser(int userId, String name, String email) - Args: [userId={123}, name={John Doe}, email={john@example.com}] - 42 ms
-```
-
-**Important:** Ensure your objects have proper `toString()` implementations for meaningful output:
-
-```java
-public class User {
-    private int id;
-    private String name;
-    private String email;
-    
-    @Override
-    public String toString() {
-        return String.format("User{id=%d, name='%s', email='%s'}", id, name, email);
-    }
-}
-```
-
-### 4. Threshold Filtering
-
-Filter out fast methods to focus on performance issues:
-
-```java
-@TimerNinjaTracker(threshold = 500)  // Only log if execution > 500ms
-public void potentiallySlowMethod() {
-    // Method logic
-}
-```
-
-**When Threshold is Exceeded:**
-```
-public void potentiallySlowMethod() - 723 ms ¤ [Threshold Exceed !!: 500 ms]
-```
-
-**When Below Threshold:**
-- The method is suppressed from the trace output
-- If all methods in a trace are below threshold, a summary is shown
-
-**Combining with Arguments:**
-```java
-@TimerNinjaTracker(includeArgs = true, threshold = 200)
-public void requestMoneyTransfer(int sourceUserId, int targetUserId, int amount) {
-    // Only logs slow transfers with full argument details
-}
-```
-
-**Use Case:** Focus on slow operations while seeing the exact arguments that caused the delay.
-
----
-
-## Block Tracking
-
-For granular tracking within a method without extracting separate methods, use `TimerNinjaBlock`.
-
-### Basic Block Tracking
-
-```java
-public void processData() {
-    // Regular code not tracked
-    
-    TimerNinjaBlock.measure("database query", () -> {
-        database.query("SELECT * FROM users");
-    });
-    
-    // More code not tracked
-}
-```
-
-### Block with Return Value
-
-```java
-public void processData() {
-    String result = TimerNinjaBlock.measure("fetch data", () -> {
-        return api.fetchUserData();
-    });
-    
-    System.out.println(result);
-}
-```
-
-### Block with Custom Configuration
-
-```java
-import java.time.temporal.ChronoUnit;
-
-public void processData() {
-    BlockTrackerConfig config = new BlockTrackerConfig()
-        .setTimeUnit(ChronoUnit.SECONDS)
-        .setThreshold(2);
-    
-    TimerNinjaBlock.measure("long operation", config, () -> {
-        performLongRunningTask();
-    });
-}
-```
-
-### Nested Block Tracking
-
-```java
-public void complexProcess() {
-    TimerNinjaBlock.measure("overall process", () -> {
-        loadData();
-        
-        TimerNinjaBlock.measure("data transformation", () -> {
-            transformData();
-        });
-        
-        saveData();
-    });
-}
-```
-
-**Output:**
-```
-{===== Start of trace context id: ... =====}
-[Block] overall process - 1500 ms
-   |-- [Block] data transformation - 500 ms
-{====== End of trace context id: ... ======}
-```
-
----
-
-## Understanding Trace Output
-
-### Trace Structure
-
-```
-Timer Ninja trace context id: a1b2c3d4-e5f6-7890-abcd-ef1234567890
-Trace timestamp: 2023-04-03T14:27:50.322Z
-{===== Start of trace context id: a1b2c3d4-e5f6-7890-abcd-ef1234567890 =====}
-public void parentMethod() - 100 ms
-   |-- public void childMethod() - 50 ms
-   |-- public void anotherChildMethod() - 30 ms
-{====== End of trace context id: a1b2c3d4-e5f6-7890-abcd-ef1234567890 ======}
-```
-
-### Elements Explained
-
-1. **Trace Context ID**: Auto-generated UUID for a trace
-   - Initiated by the first `@TimerNinjaTracker` method encountered
-   - All subsequent tracked methods in the same call stack share this ID
-
-2. **Trace Timestamp**: When the trace context was initiated (UTC timezone)
-
-3. **Start/End Markers**: Delimit the trace boundaries
-
-4. **Method Lines**: Each tracked method shows:
-   - Method signature
-   - Arguments (if `includeArgs = true`)
-   - Execution time with time unit
-   - Threshold indicator (if exceeded)
-
-5. **Indentation (`|--`)**: Shows call hierarchy
-   - Indented methods are called by the method above
-   - Helps visualize the execution stacktrace
-
-### Summary Output
-
-When all methods in a trace are below their thresholds:
-
-```
-Timer Ninja trace context id: abc123...
-Trace timestamp: 2023-04-03T14:27:50.322Z
-All 3 tracked items within threshold. min: 5 ms, max: 45 ms, total: 50 ms
-```
-
-This summary shows the range and total execution time without detailed traces.
-
----
-
-## Global Configuration
-
-Timer Ninja uses a singleton configuration class for global settings.
-
-### Enable System.out Logging
-
-For simple console applications or quick testing:
-
-```java
-TimerNinjaConfiguration.getInstance().toggleSystemOutLog(true);
-```
-
-**Note:** Call this once at application startup. By default, Timer Ninja uses SLF4J logging.
-
-### Log Level
-
-The logger class is `io.github.thanglequoc.timerninja.TimerNinjaUtil` with default level `INFO`.
-
-To see debug information:
-
-```
-<logger name="io.github.thanglequoc.timerninja.TimerNinjaThreadContext" level="DEBUG"/>
-```
-
-**Use Case:** Troubleshooting tracking issues or understanding internal behavior.
-
----
-
-## Best Practices
-
-### 1. Choose Appropriate Time Units
-
-- **Seconds**: For long-running operations (API calls, file I/O, batch processing)
-- **Milliseconds**: For general application logic (default)
-- **Microseconds**: For performance-critical code (algorithms, calculations)
-
-### 2. Use Thresholds Strategically
-
-```java
-// Too low - noise
-@TimerNinjaTracker(threshold = 10)
-
-// Too high - miss issues
-@TimerNinjaTracker(threshold = 5000)
-
-// Balanced - catches real issues
-@TimerNinjaTracker(threshold = 200)
-```
-
-### 3. Combine with Arguments for Debugging
-
-```java
-@TimerNinjaTracker(includeArgs = true, threshold = 200)
-public void searchUsers(String query, int limit) {
-    // See which queries are slow
-}
-```
-
-### 4. Track Entry Points
-
-Add tracking to high-level entry points (REST controllers, main methods) to capture full execution traces:
-
-```java
-@RestController
-public class UserController {
-    
-    @TimerNinjaTracker
-    @GetMapping("/users/{id}")
-    public User getUser(@PathVariable Long id) {
-        // All nested tracked methods will appear in the trace
-        return userService.findById(id);
-    }
-}
-```
-
-### 5. Use Block Tracking for Phases
-
-For methods with distinct phases, use block tracking instead of breaking into small methods:
-
-```java
-public void processOrder(Order order) {
-    // Validation phase
-    TimerNinjaBlock.measure("validation", () -> {
-        validateOrder(order);
-    });
-    
-    // Processing phase
-    TimerNinjaBlock.measure("processing", () -> {
-        processPayment(order);
-        updateInventory(order);
-    });
-    
-    // Notification phase
-    TimerNinjaBlock.measure("notification", () -> {
-        sendConfirmation(order);
-    });
-}
-```
-
-### 6. Disable in Production When Needed
-
-```java
-@TimerNinjaTracker(enabled = isDevelopment())
-public void debugMethod() {
-    // Only tracked in development environment
-}
-
-private boolean isDevelopment() {
-    return "dev".equals(System.getProperty("environment"));
-}
-```
-
-### 7. Don't Track Everything
-
-Focus on:
-- Critical business logic
-- External API calls
-- Database operations
-- File I/O operations
-- Complex algorithms
-
-Avoid tracking:
-- Simple getters/setters
-- Very fast operations (< 1ms)
-- Trivial utility methods
-
----
-
-## Troubleshooting
-
-### No Output in Logs
-
-1. Check if SLF4J provider is configured
-2. Verify log level is at least INFO
-3. Enable System.out for testing:
-   ```java
-   TimerNinjaConfiguration.getInstance().toggleSystemOutLog(true);
-   ```
-
-### Methods Not Being Tracked
-
-1. Verify AspectJ plugin is configured correctly
-2. Check that the dependency includes the aspect:
-   ```groovy
-   aspect 'io.github.thanglequoc:timer-ninja:1.2.0'
-   ```
-3. Ensure `enabled = true` (or not set) on the annotation
-
-### Missing Method Arguments
-
-1. Set `includeArgs = true` on the annotation
-2. Verify `toString()` is implemented for argument objects
-3. Check if objects are null or contain sensitive data
-
-### Inconsistent Tracking
-
-1. Ensure you're using the correct version (1.2.0 or later)
-2. Check for conflicting AOP configurations
-3. Review logs for DEBUG information
-   ```xml
-   <logger name="io.github.thanglequoc.timerninja.TimerNinjaThreadContext" level="DEBUG"/>
-   ```
