munin and nagios

[mimo <mimo@restoel.net>]

I wonder if anyone has run into this (and found a solution). I have a fairly 
complex munin installation with multiple hosts. Also, I have set warning and 
critical threshholds in munin and configured it to use send_nsca in case a 
warning or critical limit gets hit. This sends the warning to nagios from 
where I want to send it on using nagios features of when to send it where 
(E-mail or sms). Now the problem is that nagios complains that the host and 
service is not defined in the nagios config. According to nagios docs there 
seems to be no way around putting all possible services and all possible 
hosts I want to monitor into its config. From experience, I'd rather not do 
this. As it means alot of work when adding hosts or adding monitors to munin. 
Is there a way to create objects for any passive checks that get send to 
nagios or should I look at a different system alltogether for processing and 
sending out the alerts? nagios is quite nice as it gives a history and also 
sends out a critical only once and not every 5 mins...

thanks
