>>! From {T336774}:
> Ideally both answers are 'no', but regardless I'd like to move the `labs` instance of Prometheus off cloudmetrics and onto the Prometheus production hardware. My understanding is that this move will help both WMCS (one less component to think about) and Observability (less variance/snowflakes).
== Action plan ==
* [ ] Update `cr` firewall rules to allow this traffic (T343885#9119388)
* [x] Add a new `profile::prometheus::cloud` class (and rename `labs` to `cloud` in the process)
* [x] Allocate space on prometheus LVs (`eqiad` only) (`modules/prometheus/files/provision-fs.sh`)
* [x] Deploy said class to `prometheus` hosts (`eqiad` only), making sure `alertmanagers` parameter is not set so alerts won't be sent.
* [x] Verify Prometheus can pull metrics from all its jobs.
* [x] Let metrics data accumulate for TBD days
* [x] Enable alerts to be sent from `prometheus`, disable alerts from `cloudmetrics`
* [x] Audit accesses on cloudmetrics hosts for Prometheus clients
* [x] Update cloudmetrics references to point to `prometheus.svc/cloud` instead
== Followups ==
* [x] Add thanos upload/sidecar
* [ ] Remove `labs` Prometheus instance from `cloudmetrics`
* [ ] Duplicate setup to `codfw`?
* [ ] Rename grafana datasource to `eqiad prometheus/cloud`. These dashboards will need updating: https://phabricator.wikimedia.org/P53026
