Monitor Control Callback Methods

A resource type implementation optionally can include a program to monitor the performance of a resource, report on its status, or take action on resource failure. The MONITOR_START, MONITOR_STOP, and MONITOR_CHECK methods support the implementation of a resource monitor in a resource type implementation.

• MONITOR_START - This optional method is called to start a monitor for the resource after the resource is started.

• MONITOR_STOP - This optional method is called to stop a resource's monitor before the resource is stopped.

• MONITOR_CHECK - This optional method is called to assess the reliability of a node before a resource group is relocated to the node.
