notification not working
Posted: Wed Apr 10, 2013 11:17 am
Hi there,
I wrote a simple plugin in perl called "check_temperature.pl", and placed this plugin on both the
nagios monitor (localhost) and a remotehost. The check_temperature is called through check_nrpe as shown in the following service
definition
On the web interface, I can see the status changes from OK to CRITICAL, however, the Last Notification shown as N/A (notification 0).
However, if I define the "check_local_temperature" on the local machine, I got email notification. On the remotehost, I got email
notification for some other services such as check_disk. Below is the simple plugin. Could someone enlighten me why the
notification is not working? Thanks a lot!
