Hello fellow Nagios users, I have configured a couple of hosts in Nagios, since they are the nodes of a HA cluster the services are running on the active host only. As obvious Nagios is showing the services down on the passive host. I tried using check_cluster and check_cluster2 but due to the lack of information around the web and mailing list archives I couldn't figure out how it can be configured. Would anyone actually using check_cluster like to lend me a hand? :) We are using Nagios Core 3.2.0 on Centos. Thanks, Ashish Kumar
