Request Profiling

Procedure

1. Grab the profiling token from Monitoring > Requests Profiles admin page (highlighted in a blue in the image below).
2. Pass the header X-Profile-Token: <token> and X-Profile-Mode: <mode>(where <mode> can be execution or memory) to the request you want to profile. You can use:
   • Browser extensions. For example, ModHeader Chrome extension.
   • curl. For example, curl --header 'X-Profile-Token: <token>' --header 'X-Profile-Mode: <mode>' https://gitlab.example.com/group/project.
3. Once request is finished (which will take a little longer than usual), you can view the profiling output from Monitoring > Requests Profiles admin page.

Cleaning up

Profiling output will be cleared out every day via a Sidekiq worker.
