Problem Statement

Combining Log streams from multiple sources

We want to create an application with which you can view the logs of multiple different systems in one place. The logs can come from various sources which use different technologies for providing their Logs. These could include:

• A Http Api
• A Kafka Topic
• WebSockets
• ...

The application should be able to handle logs from multiple sources and display them in a single view.

Additionally, the application should be able to filter the logs based on an input string and display only the logs that contain the input string.

Structure

The project is divided into 3 parts:

• Frontend containing the SPA Angular Application frontend
• Backend containing the Spring Webflux Server backend
• Sample Code used in the presentation rxjs-samples
