Yes, that is what you want to do. It's what I did. First, make sure you've defined all your VM hosts. The check_cluster command will collate their states to determine the cluster's state. Then, define a command to check your clusters. This one can check hosts or services, depending on what you pass for $ARG1$. ----- define command { # # $ARG1$ is either "host" or "service" # command_name check_cluster command_line $USER1$/check_cluster --$ARG1$ --label=$HOSTNAME$ --warning=$ARG2$ --critical=$ARG3$ --data=$ARG4$ } ----- Next, define a host to represent your cluster. I pass "host" as $ARG1$. I set a warning if one is not-OK and critical if two or more are not-OK. I don't recall where I saw the use of the @ and : documented in defining thresholds, but I seem to recall that without the "or more" part the check will do something odd when a third VM host goes down. ----- define host { use generic-server host_name cluster_1 alias cluster_1 parents foo1,foo2,foo3,foo4 check_command check_cluster!host!@1:!@2:!$HOSTSTATEID:foo1$,$HOSTSTATEID:foo2$,$HOSTSTATEID:foo3$,$HOSTSTATEID:foo4$ } ----- I also define a service check for the cluster so I don't run into service-less hosts not showing up on Nagios' web pages. ----- define service { use standard_service host_name cluster_1 check_command check_cluster!service!@1:!@2:!$SERVICESTATEID:foo1:Ping$,$SERVICESTATEID:foo2:Ping$,$SERVICESTATEID:foo3:Ping$,$SERVICESTATEID:foo4:Ping$ } ----- Nothing in this message is intended to make or accept an offer or to form a contract, except that an attachment that is an image of a contract bearing the signature of an officer of our company may be or become a contract.
