Decommission 'coal' and 'coal-web' services
Closed, ResolvedPublic

Description

As of change 908220 last week, we no longer display Coal metrics on the https://performance.wikimedia.org/ homepage.

For monitoring, we now use Grafana alerts (done).
For the homepage, we now embed Grafana panels (done).
For long-term stability we are transitioning to Prometheus (not a blocker, in progress: T175087).

21:34:16 <Krinkle> cwhite: it seems 'coal' is still running on webperf1003. I guess we didn't absent it and/or intentionally removed it simply with intention to remove by hand but haven't yet?

Stopped and removed units for coal, uwsgi-coal, wmf_auto_restart_coal and wmf_auto_restart_uwsgi-coal.
