Multiple serviceMonitor issues

[sebzimmermann]

Additional labels not working

When adding additionalLabels in the metrics section of the values.yaml file, e.g.

  metrics:
    serviceMonitor:
      enabled: ${service_monitor_enabled}
      namespace: ${namespace}
      interval: 30s
      scrapeTimeout: ""
      relabellings: []
      metricRelabelings: []
      honorLabels: false
      additionalLabels:
        release: grafana
      podTargetLabels: []

The following error occurs:

Error: template: parseable/templates/service-monitor.yaml:9:8: executing "parseable/templates/service-monitor.yaml" at <include>: wrong number of args for include: want 2 got 1

Custom port does not exist

The serviceMonitor wants to bind the endpoint port as parseable-metrics. This custom named port does not exist and should be replaced with the existing parseable-port.

Endpoint path not defined

The serviceMonitor does not define an endpoint path. It should point to /api/v1/metrics

Matched labels do not exist

The serviceMonitor has the following selector:

selector:
    matchLabels:
      app.kubernetes.io/instance: parseable
      app.kubernetes.io/name: parseable

but these labels do not exist on the parseable service object(s). The only label on the services is app.kubernetes.io/managed-by=Helm
