Learn about configurations >

• enable-autodiscovery | boolean

  Default: True

  By default, grok exporter will automatically expose the metrics defined in files/metrics-mapping.yaml if the log files they are referred exist on the unit. To prevent this mechanism, set this option to false.

  Default: True

  Grok exporter will not start if the log files to monitor don't exist if this is set to true.

  Default: /var/snap/prometheus-grok-exporter/current/logstash-patterns-core/patterns

  Default: juju

  A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.
