@Harej What exactly do you want to measure? The availability of the https://paws.wmflabs.org/paws/hub/login entry page, or something more complex like the ability of PAWS to spawn a new container as a particular Wikimedia user account?

More along those lines. Going to paws.wmflabs.org by itself seems to work consistently, but the Start My Server button works inconsistently and I'd like to begin tracking when it works and when it doesn't.

Jupyterhub 0.9 will come with prometheus metrics. See https://paws-beta.wmflabs.org/paws/hub/metrics

server_spawn_duration_seconds_count{status="failure"} might take care of that.

There will also be prometheus metrics from the notebooks soon.

Change 441514 merged by Andrew Bogott:
[operations/puppet@production] prometheus: tools: scrape paws metrics into prometheus

https://gerrit.wikimedia.org/r/441514

@Andrew Thanks for the merge. I can't verify the resulting file due to permissions, but since puppet has run in tools-prometheus-01 and the log indicates /srv/prometheus/tools/prometheus.yml should now have the new paws-hub target should be set up correctly. https://tools-prometheus.wmflabs.org/tools/targets still does not have it. Perhaps a prometheus service reload/restart is needed?
