Auto-clearing passive checks

[Andrew Laden]

Heya

I am running Nagios with snmptraps being caught in the usual
passive/volitile check method. 

The big downside with this setup is that those traps will never clear. I
have to manually submit a passive check to clear them, which is
annoying.

So I want to build an active check that I can use to auto-clear them
with the following paramaters.

If the service is currently ok, Return OK.
If the service is currently non-ok and the last non-ok passive check
state is less then x minutes old, return the current state.
If the service is currently non-ok, and the last non-ok passive check
state is greater then x minutes old, Return ok. (ie, reset the state)

I see a few problems with this.

1: With volatile being set, every time the auto-clear check runs, it
will re-notify.
2: I have no way of getting the last time that a passive check reported,
only the time that the service changed from OK to Non-ok. (ie, if a
passive check sends a non ok, at time 0, and again at time 30. I want
the reset to occur as x+30, not x.)

My leaning then is to do this outside of nagios. And run a script that
checks the status file, looks for services that meet the requirements.
(passive only, non-ok, Last update greater then x) and submit a passive
check to reset them.

Anyone else have any innovative solutions to this?

Thanks
-Andrew
