The syntax for check_cluster is quite subtle and not obvious. I confess I don't use check_cluster for service checks, but I do for host checks. An example which I use for a pair of hosts is: In the command definition: command_line $USER1$/check_cluster --host -l $ARG1$ -w $ARG2$ -c $ARG3$ -d $ARG4$ And in the host definition: check_command check_host_cluster!"Storage Server"!0!1!$HOSTSTATEID:ds4100y1a$,$HOSTSTATEID:ds4100y1b$ In my example I want to have a warning state if one of the two hosts is down and have a critical state if both are down. The important point to note is that the warning and critical thresholds are set according to the documentation at http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFORMAT It can take a while to work out precisely how to set -w and -c to achieve the result you want. hth, Jim ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
