Status of the resources in heartbeat clusters using crm=yes

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

This check uses the output of the crm_mon command as sent by the Check_MK linux agent. The check uses the information about the nodes and resources in the command output.

The check will report a CRITICAL state when the reported state is not Started. In addition the check can report a problem if a resource is not handled by a specified node.

Till version 1.2.5i6 the check nailed down the DC to the node which was DC during inventory. This has been changed to not nailing down the node. You can change this back to the old default by changing your configuration.

Discovery

On each node one service for each resource group or resource will be created. If heartbeat_crm_resources_naildown is set to True, then for each resource the current node of that resource is hardcoded as target parameter and will be checked in future. One service will be created for reach resource group or resource. If naildown_resources is set to True in inventory_heartbeat_crm_rules, then the node which is currently holding the resource will be required to also hold it in future.
