Create check called check_dns_cache in checkcommands.cfg calling check_dns or whatever you are using and use $ARG1$ as a macro thats passed to it. In services.cfg you define the check as check_command check_dns_cache!1.2.3.4 where <a href="http://1.2.3.4">1.2.3.4</a> is the IP you want to be passed to $ARG1$ Least thats how ive set it up.

I was wondering if it is possible to define 'custom macros' that can be defined per host. For example, we have the $HOSTADDRESS$ macro which can be referenced in the 'command' definition, but what if I have some other attribute I'd like to specify that's not part of the 'host' object by default. In particular, our DNS caches run on their own IP address (interface) different from the rest of the services on the boxes. I don't want to define new hosts for this because that would be ugly, mistake prone, confusing in the HTTP UI etc. Instead I'd like to define a new check command called check_dnscache which uses $DNSCACHEADDRESS$ instead of $HOSTADDRESS$ in it's command line. Can anyone make a suggestion on how to do this?
