Prometheus API URL

I’m trying to add metrics to our environments but I don’t see anything other than a button to look at the documentation.

I have a GitLab CE Omnibus installation which came bundled with Prometheus so the only thing I really needed to do is to enable it which I did and it seems to work.

However I think I supplied the wrong API URL when setting up the Prometheus integration on our project.

Our GitLab is accessible through and I thought I would use that URL for the Prometheus API URL as well. Am I wrong on this one?

I think is the wrong API URL here. But I don’t really know where to find the proper value. Is it in /etc/gitlab/gitlab.rb?
