Nagios Support Forum

Long story short, if we experience a major outage, nagios will send down and recovery emails for hours. Is there a way to clear this manually? I have tried mailq, but nothing is listed.

[root@localhost ~]# mailq
Mail queue is empty

First, a question: are you getting notifications now or are you just looking to prevent a flood in the future?

There are at least a couple of way to tackle this. What's the output of ps -ef | grep bin/nagios | grep -v grep? It's possible there's actually a problem with your notifications.

You can disable notifications when an outage occurs, but you need to remember there are both host and service checks.

If you set your notification_interval to 0, it will only notify you once about a down host / service.

There's additional info at https://assets.nagios.com/downloads/nag ... ios-XI.pdf.

Please let us know if you need additional help understanding your options on reducing notifications.

Heres the output. We are still getting alerts right now. I have ran postsuper -d ALL and it is still sending emails. We put in a acl to block the traffic from the Nagios server, so I know its all coming from Nagios.

You can shut off all of the notifications being sent by Nagios XI by going to the Admin > Monitoring Engine Status menu in the GUI and clicking the X next to the Notifications setting in the Monitoring Engine Process dashlet.
Stop Notifications until the system catches up and then re-enable it.
Then go to the Admin > Manage Email Settings menu, if the Mail Method is set to SMTP, then someone would have to login to that server to flush the rest of the emails.
