Monitoring clustered services

[Schimpke, Dr. Thomas - bhn]

Hello Ashish,

is there a "virtual IP adress" connected with the service (like the 
package IPs in ServiceGuard) ? If there is: simply monitor the service 
by using the IP associated with the service and monitor the individual 
hosts, the service might be running on. You may want to monitor and 
notify the hosts using the check_cluster plugin.

check_cluster is useful for active/active clusters. In active/passive 
clusters you'll get a lot of red services and that is probably not what 
you want and the reason for your question.

Kind regards,

Thomas
