Nagios Support Forum

FYI ,All settings are perfect. We are even getting test alert messages to our phone . But we are not getting automated alerts when host or service goes down

We would have to see your System Profile and the output of the commands from my previous post to continue on with the troubleshooting.
You could try this KB article to see if you can resolve the Profile Build Failure.

If this article does not work for you, can you run the following as root and post the output? If you are using a SMTP server to forward the emails, can you login to it and check the logs to see if they are getting blocked?

Attached second command output as info.txt

The settings seem to be correct for the following user accounts.
Nagios Administrator
Naveen
Sai Kuppam
John Anto

These accounts the SMS notifications are not enabled so they will have to login to the server and enable the SMS Notification Method.
Chandra Pedapudi
Rajesh Basa
Chakrapani

Login to the XI GUI and go to the Home > Notification menu and verify that the user's SMS notification was sent when the host or service was down, etc....

If you see the entry that the Notification was sent but never received, login as root to the Nagios server and check this log files for any errors on why it was not sent.
/usr/local/nagiosxi/tmp/phpmailer.log

If you need any help on the errors, post them here.
