Nagios Support Forum

I have Nagios core 3.3.1 installed and email notifications had always been working right from the start with not special setup. Recently I noticed that emails are not being sent. I dont know what might have changed. I would like to eliminate the nagios box as the issue if possible. Could anyone lead me to what I can try to find out where the issue lies.
thanks!

Check your main config file first and see if you have:

it is enabled

You can see if all of the filters are passed in order for the alerts to be sent:

You can also check if sendmail is working fine. Create a test file somewhere and e-mail it to a good known e-mail address, for example, you can run in terminal:
You can also double check your spam folder

Hope this helps.

I must be missing something I go to send a test email and it said "mail delivery status report will be mailed to <root>.

Code: Select all

/usr/lib/sendmail -v <your_e-mail> < /tmp/test.txt

Check the root mail - it may help you troubleshoot the issue:
