NagiosXI keep mailing alert?!

[xpertech]

There're thousands of monitoring services & hosts, this morning some networks failed, NagiosXI detect and then email notification alerts, but after network problem fixed, it still kept sending notifications, the administrators keep receiving alerts, until changing NagiosXI SMTP Server to another IP and then it stop, what could be the problem?

If that happen again, how to quickly stop NagiosXI keep sending hundreds/thousands notifications until network problem fixed?

To stop notifications on "per user" basis, go to, where x.x.x.x is your XI IP:

Code: Select all

http://x.x.x.x/nagiosxi/account/

Then click notification preferences on the right, then uncheck the enable notifications box.

To stop notifications "globally", go to Admin > System Information > Monitoring Engine Status, and click on the "X" (the "Disable" action button), next to the "Notifications". You can re-enable notifications, when the situation is "under control".

Note: It is possible that these emails were already in the mail queue, so they were sent anyway. Also, there are cases when emails are sent (even though the shouldn't be sent) when there are multiple instances of nagios running. To check if there are multiple nagios processes running, run:

Code: Select all

ps -ef | grep nagios.cfg | grep -v grep

Can you post the config file of one of the host/services that continued sending notifications, also any relevant templates if you use those?
