Maintenance won’t page you

A backend or server set to MAINT or DRAIN holds its alert instead of resolving it, so planned work stays quiet.

  • Read from the stats socket or the stats page
  • The status of every server behind each backend
  • 4xx, 5xx and retries per backend
  • Alert on the whole backend, or on each server
