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? :)</blockquote> i'd suggest using check_multi instead for checking real clustered services. <blockquote cite="mid:CAKjbCD5wLbG=U12+05O0PQbbUQQRsGU_xCZpi6_TNmo18aPtEQ@mail.gmail.com" type="cite"> We are using Nagios Core 3.2.0 on Centos.
