Heartbeat Cluster: Node Status and Link Status
Distribution	official part of Check_MK
License	GPL
Supported Agents	Linux

This check uses the output of several cl_status calls as sent by the Checkmk linux agent to monitor the status of the linked nodes in a heartbeat cluster. Additionally all links of each node are checked.

Each configured linked node will result in one service during inventory.

The check will result in a CRITICAL state when the nodestatus is not "up", "ping" or "active". A link status different than "up" will also result in a CRITICAL state.

Item

The name of the node as configured in the ha.cf configuration file.

Discovery

One service is created for each node of a cluster.
