# Tracing **(FREE)**
|
|
|
|
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/7903) in GitLab 11.5.
|
|
> - [Moved](https://gitlab.com/gitlab-org/gitlab/-/issues/42645) from GitLab Ultimate to GitLab Free in 13.5.

|
|
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.

## Install Jaeger
|
|
|
|
[Jaeger](https://www.jaegertracing.io/) 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](https://www.jaegertracing.io/docs/latest/getting-started/).

## Link to 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 > Monitor** and provide the Jaeger URL.
|
|
1. Click **Save changes** for the changes to take effect.
|
|
1. You can now visit **Monitor > Tracing** in your project's sidebar and GitLab redirects you to
|
|
the configured Jaeger URL.
