Monitoring clustered services

[Marc-André Doll]

Hi,

One way to use check_cluster is :
 first : define a command like 
define command {
  command_name check_cluster_service
  command_line $USER1$/check_cluster -s -d $ARG1$ -c $ARG2$
}

 then define your check
define service {
  ...
  check_command  check_cluster_service!$SERVICESTATEID:node1:ha_service
$,$SERVICESTATEID:node2:ha_service$!1
  ...
}

This will get the result of the tests of the "ha_service" on "node1" and
"node2" and return a critical state if there is more than 1 check in a
non-OK state.

But the best way to check a cluster is to check only the system (disk,
CPU, ...) on your nodes and check the cluster as if it is a classic
server through th VIP.
