Not all GitLab Prometheus metrics are working

I am relatively new to GitLab and struggle with making use of the metrics provided by GitLab. I followed the steps described in the GitLab documentation to activate the embedded Prometheus endpoint under /admin/application_settings/metrics_and_profiling.

When I curl the /-/metrics endpoint from the GitLab docker container, Prometheus is working and provides a subset of the available metrics.

The problem is, that Prometheus is not providing all of the available metrics. For example the following metrics are not working:

  1. gitlab.unicorn.workers
  2. gitlab.transaction.event_push_branch_total

But the metric gitlab.puma.max_threads is working fine.

Do I have to activate the other metrics somehow?

Thank you

Solution

  • For anyone who is stumbling on the same behavior, I found the problem for this. After enabling Prometheus only those metrics are reported, that have been executed at least once. After pushing a branch to the repo, the metric gitlab.transaction.event_push_branch_total was visible as well.
