Introduced in GitLab Ultimate 11.5.
Tracing provides insight into the performance and health of a deployed application, tracking each function or microservice which handles a given request.
This makes it easy to understand the end-to-end flow of a request, regardless of whether you are using a monolithic or distributed system.
Jaeger is an open source, end-to-end distributed tracing system used for monitoring and troubleshooting microservices-based distributed systems.
GitLab provides an easy way to open the Jaeger UI from within your project:
- Set up Jaeger and configure your application using one of the client libraries.
- Navigate to your project’s Settings > Operations and provide the Jaeger URL.
- Click Save changes for the changes to take effect.
- You can now visit Operations > Tracing in your project’s sidebar and GitLab will redirect you to the configured Jaeger URL.
