Tracing (FREE)

• Introduced in GitLab Ultimate 11.5.
• Moved 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.
