GitLab Exporter

I was wondering if anyone has tried to configure and use some of the GitLab exporters?
I am using an Omnibus GitLab. I followed the instructions for configuring GitLab exporter here but when I try use localhost:9168 as data source in grafana, I keep getting 404 error which makes me think there is more to configuring this exporter than just enabling it.

Thanks in advance :slight_smile:
