<p class="MsoNormal" style="margin-bottom:12.0pt">Hello fellow Nagios users,<br>
<br>
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.<br>
<br>
Would anyone actually using check_cluster like to lend me a hand? :)<br>
<br>
We are using Nagios Core 3.2.0 on Centos.<br>
<br>
Thanks,<br>
Ashish Kumar<br>
