PrometheusRule for alerting on misconfigured logging-operator objects

[PlayMTL]

Hey,

i wrote a small prometheus rule, which alerts on misconfigured logging objects. I'm using it currently to monitor flows & outputs.

You need at least version 4.3.0

apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
  name: logging-operator
  namespace: logging-operator
spec:
  groups:
  - name: logging-operator
    rules:
    - alert: ErrorInLoggingConfiguration
      annotations:
        description: >-
          Error in LoggingObject kind: "{{ $labels.kind }}" in namespace "{{ $labels.exported_namespace }}" with name "{{ $labels.name }}"
        summary: error or misconfiguration for logging-operator, pls check the logging-operator logs
      expr: logging_resource_problems >= 1
      for: 2m
      labels:
        rulegroup: logging-operator
        service: logging-operator
        severity: critical
