Hi All

iam configuring for the first time Nagios monitoring system on my raspberry Pi, evrything is working fine.
Only notifications wil not being sent out. I have tried a lot but nothing works....
can someone help me out with this ?
iam monitoring a ip cam in my own network when i bring the interface down i see in Nagios that it's offline but no notifications will be send out.
Notification is enabled see my configurations below.



define host{

; in (or inherited by) the linux-server host template definition.

I hope somebody can help me out with this.

Can you bring down the interface on the camera, trigger the notification, and then run tail -n 200 /var/log/maillog? Please post back the result.

One other thing, can you post / PM your objects.cache file? It's located at /usr/local/nagios/var/objects.cache
