Notification for change in critical state

[Stijn Gruwier]

Hello,

I have a similar issue but with multiple netapp volumes instead of 
multiple ip addresses being checked by one plugin. Wat might be a 
solution is is submitting (enough) checkresults to the external command 
file in your check script, forcing a different state, like unknown, wich 
will triger a notification when it goes back to critical/warning....

This can be done with the external command process_service_check_result, 
maybe like this:
PROCESS_SERVICE_CHECK_RESULT;routername;check-multiple-ip;3;One 
more/less ip address is down

Then when your check script returns CRITICAL there will be a state 
changes from critical -> unknown -> critical and notifications will be 
sent. For this you'd need passive service checks enabled for the service 
and there should be a delay between submitting the external command and 
the plugin exit, so nagios has time to process the check results and 
change the service state.
 This isn't perfect, there will be 2 notifications, but maybe by 
disabling notifications for the unknown state there will be only 1 (or 
0, I don't know?).
