# Tracing **(ULTIMATE)**
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/7903) 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 tracing
|
|
|
|
[Jaeger](https://www.jaegertracing.io/) is an open source, end-to-end distributed
|
|
tracing system used for monitoring and troubleshooting microservices-based distributed
|
|
systems.
|
|
|
|
### Deploying Jaeger
|
|
|
|
To learn more about deploying Jaeger, read the official
|
|
[Getting Started documentation](https://www.jaegertracing.io/docs/latest/getting-started/).
|
|
There is an easy to use [all-in-one Docker image](https://www.jaegertracing.io/docs/latest/getting-started/#AllinoneDockerimage),
|
|
as well as deployment options for [Kubernetes](https://github.com/jaegertracing/jaeger-kubernetes)
|
|
and [OpenShift](https://github.com/jaegertracing/jaeger-openshift).
|
|
|
|
### Enabling Jaeger
|
|
|
|
GitLab provides an easy way to open the Jaeger UI from within your project:
|
|
|
|
1. [Set up Jaeger](https://www.jaegertracing.io) and configure your application using one of the
|
|
[client libraries](https://www.jaegertracing.io/docs/latest/client-libraries/).
|
|
1. Navigate to your project's **Settings > Operations** and provide the Jaeger URL.
|
|
1. Click **Save changes** for the changes to take effect.
|
|
1. You can now visit **Operations > Tracing** in your project's sidebar and
|
|
GitLab will redirect you to the configured Jaeger URL.
