Problem to solve

Describe your question in as much detail as possible:
I have a self-hosted GitLab and I wanted to Generate DORA Metrics Charts in Grafana collecting them with Prometheus. I set up the following configs in the gitlab.rb( The linux distribution)

gitlab_rails['prometheus_enabled'] = true
gitlab_rails['monitoring_whitelist'] = [...]
sidekiq['metrics_enabled'] = true
gitlab_exporter['listen_address'] = '0.0.0.0'
gitlab_exporter['listen_port'] = '[port]'

I also have the Prometheus metrics turned on from the admin panel.

So, for now I am able to run curl http://ip:port/metrics and get metrics but they only consist of sidekiq, ruby, gitlab_database_rows. I miss the key metrics that I need to derive the DORA metrics. I tried to access curl http://ip:port/-/metrics but this returns an error instead.

  • What are you seeing, and how does that differ from what you expect to see?
    I expect to run curl http://ip:port/-/metrics and get the metrics like on curl http://ip:port/metrics but it returns Sinatra doesn't know this ditty. I need help getting access to these metrics.
