[Nagiosplug-help] Problem with Email Alerts

[Ian Rarity]

Hi Narasimha,

The default notify command that’s being run is notify-host-by-email, which just uses /bin/mail to do the actual sending.  Can you use mail to send a test message from the command line?  If not, that’s your problem.
It may also be worth looking in your mail server’s logs; these will probably be somewhere like /var/log/mail or /var/log/maillog, and should indicate if a) the mail is being correctly send to your MTA, and b) whether or not the MTA has any problems delivering it.

Ta,
IR.

Hi David

What is the default command Nagios uses to send mail?.
I found some thing in log files like below.

[09-03-2009 21:25:02] Warning: The results of service 'Current Load' on host 'ec2-75-101-200-287.compute-1.amazonaws.com' are stale by 0d 0h 3m 7s (threshold=0d 0h 3m 15s). I'm forcing an immediate check of the service.
