* forward\_alert\_rules | boolean

  Default: True

  Toggle forwarding of alert rules.
* nrpe\_alert\_on\_warning | boolean

  Enable alerting on NRPE warnings

  When true, the expression changes from `round(avg_over_time(command_status) > 1` to `round(avg_over_time(command_status) >= 1` and alerts will still be labelled as `severity: warning`.
  From the NRPE severity calculation, `1` means warning and `2` means critical.

  Warning: some users may have dynamic alerting (e.g. in PagerDuty) and these would warnings could flood notifications.
