No email notify for new host

[hellb0y77]

I defined new host in nagios, but when service and host state is critical or down, Nagios does not send email notification, which files should I change?

Bookmark the Nagios documentation and then read http://nagios.sourceforge.net/docs/3_0/ ... tions.html

In addition, you might be sending emails but they are not routing properly. Check your /var/log/maillog for possible errors.

You can also do this to make sure that Nagios is even trying to send a notification in the first place:

Code: Select all

grep NOTIFICATION /usr/local/nagios/var/nagios.log

If you don't see any results, then Nagios's notification systems aren't even being triggered. If you see things like the following example, then it's trying, but the emails aren't getting to you.

Code: Select all

SERVICE NOTIFICATION: twitter;Bitnetix:WWW;Load;OK;notify-service-by-twitter;OK - load average: 0.37, 0.39, 2.47

(Note: We have a twitter notification thingy, so don't get hung up if you don't see "twitter" in your results.)

Give us a holler when you have the above results hellb0y, on the note of checking your maillog, on a centos/rhel/most standard linux based systems it is located at:

Code: Select all

/var/log/maillog
