Great question. I've been thinking about that a bit myself, but just haven't had time to really work on it. My thought so far would be to do something like this: Create a "wrapper" plugin that can execute two (or more) "regular" plugins and capture the return value of each. The wrapper plugin would then alert only if a certain combination of return values are received. For your purposes here, the wrapper plugin would return CRITICAL only if both "regular" plugins also return CRITICAL For what you're trying to do, (and what I'm up to as well) your two regular plugins would be: 1. Whatever normal plugin you're using to check the host/service in question 2. check_nrpe using the same plugin as (1), but running on your second host. The "wrapper" plugin could be used as both a service check and a host check, so you could make every host/service you're monitoring be checked from two (or more) systems but only alert if all or some combination of "check hosts" return CRITICAL. The only drawback here is that all the alerting is still funneled through your primary Nagios host, so if it is unavailable you get no alerts. But that's where failover monitoring can come in, which is fairly well documented and would complement this setup pretty nicely. I'm guessing the "wrapper" plugin would take only an hour or two to hack out in Perl (Much less for someone more skilled than I)...I just haven't had the time to devote to this particular project. If anyone does take the time -- let me know, I'm happy to help test.
