Comment:

 i think most of the work here is done. there are still open issues on
 grafana, namely authentication (#30023) and deployment (#30026) but I
 don't think those are a priority in the grand scheme of things right now.
 there's also the wider question of monitoring of third-party services, for
 example in #30152 that i consider out of scope for this original
 deployment, along with an eventual nagios replacement.

 because everything is covered by other tickets, I will make the call and
 claim the first phase of this project is complete.

 TL;DR: done! Next steps:

  * #30023 - grafana authentication
  * #30026 - grafana docker deployment
  * #30152 - third-party monitoring
  * #29864 - nagios replacement
