Invoke-IcingaCheckClusterHealth¶

Description¶

Checks the state and availability of a Cluster Service

Invoke-IcingaCheckClusterHealth checks generally for the state of the Cluster, i.e. it checks if the Cluster service is running properly, the state of all Cluster Nodes and all Cluster Resources like “Task scheduler”, “Clustername” etc. If the Cluster Main Server fails, the check is automatically CRITICAL, because then the cluster is no longer available and the cluster service is Stopped.

Verbosity	Object	false	0	Changes the behavior of the plugin output which check states are printed: 0 (default): Only service checks/packages with state not OK will be printed 1: Only services with not OK will be printed including OK checks of affected check packages including Package config 2: Everything will be printed regardless of the check state 3: Identical to Verbose 2, but prints in addition the check package configuration e.g (All must be [OK])
