News/2023 Cloud VPS metrics changes

From Wikitech

This page details information about the changes to Cloud VPS metrics systems in mid 2023.

What is changing?

Relevant changes that happened previously

  • Debian 11 (released mid 2021) no longer includes Diamond, which produced machine-level stats for Graphite.
  • From November 2022, a Prometheus instance (at prometheus.wmcloud.org) has been collecting machine-level statistics using prometheus-node-exporter on all VMs.

What is changing now?

What should I do?

Migrate dashboards (and other tools) to use Prometheus data

You should migrate any affected Grafana dashboards and other tools you find useful to load data from Prometheus instead of loading it from Graphite.

If your project needs Graphite for a reason other than per-machine statistics and can't move to Prometheus, you need to run your own Graphite instance instead of relying on the WMCS-hosted instance.

Migrate dashboards from grafana-cloud.wikimedia.org to grafana.wmcloud.org

You should move any Grafana dashboards you find useful on grafana-cloud.wikimedia.org to grafana.wmcloud.org.

There is a dump of all of the dashboards that existed on grafana-cloud before its shutdown.

Why are we doing this?

  • We are replacing Diamond metrics with Prometheus based ones because Diamond is written in Python 2, which is no longer supported on latest versions of the Debian operating system.
  • We are shutting down the Graphite server because its primary purpose was to collect Diamond data.
  • We are replacing the old Grafana instance because new versions of Grafana no longer supports the setup we currently have.
