action points:

  • lint rules before merge (already filed as prometheus-alerts#1 (closed), will followup there)
  • don't restart prometheus forever (filed https://bugs.debian.org/1022724, https://salsa.debian.org/go-team/packages/prometheus/-/merge_requests/5, deployed an override through puppet)
  • prometheus shouldn't flood its logs with WAL notices if there's a syntax error (filed https://github.com/prometheus/prometheus/issues/11486)
