Tracing provides insight into the performance and health of a deployed application, tracking each function or microservice that handles a given request. Tracing 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. To learn more about installing Jaeger, read the official Getting Started documentation.
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 redirects you to the configured Jaeger URL.
