Hi Roy, I'm afraid there are no test instances you can use. But we do have one "shared" Prometheus instance running in Cloud VPS that scrapes metrics from many Cloud VPS projects.
One thing you could do is expose some test metrics to an endpoint like https://libraryupgrader2.wmcloud.org/metrics and ask for that endpoint to be added to the "scrape targets" of the shared MetricsInfra Prometheus instance.
There is some documentation at https://wikitech.wikimedia.org/wiki/Portal:Cloud_VPS/Admin/Monitoring#Metric...
We have some plans to make it easier to add custom metrics and alerts for any Cloud VPS project, but this will take some time, see https://phabricator.wikimedia.org/T284993
HTH, Francesco
