Suppress All alerts from Nagios

[jsalsbury]

Good morning or afternoon
I was recently approached by out patching team that most if not all of our servers are going to undergo maintenance. Is there a was to just turn off all Nagios alerting for a few hours?

Hi @jasalsbury,

Yes. You can use the scheduled downtime feature in Nagios XI. Go to Home > Incident Management > Schedule Downtime and select all hosts and the schedule downtime for associated services option (see guide below).

Nagios XI Configuring Downtime

Alternatively, you can turn off notifications in the main configuration file.

See: https://assets.nagios.com/downloads/nag ... gmain.html

Hello, @jsalsbury. There are a few ways to do that. You can open:

/usr/local/nagios/etc/nagios.cfg

And change:

enable_notifications=1

to

enable_notifications=0

And then restart the nagios service to apply changes:

service nagios restart

Or can do it from the GUI by clicking on the X next to "Notifications":

Thank you, very helpful.

One last question, they won't build up and all send out once they are turned back on right?

@jsalsbury, Not if you turn them off before hosts go into a critical state and notifications go out to the mailing queue. In that case, you can run the following query to clear out the notification tables in the database(and that should stop notifications):

echo "truncate table xi_events; truncate table xi_meta; truncate table xi_eventqueue;" | mysql -uroot -pnagiosxi nagiosxi

I also found this, It looks as if i could turn off services alerts and still have the same outcome?

[npolovenko]

@jsalsbury, Yes, scheduled downtime would work as well. Especially if you don't have that many service and host checks. I'd not recommend scheduling downtime for 10 thousand hosts and services though. In that case two options I mentioned earlier would work better.

Outstanding

@jsalsbury, I will be closing this thread as resolved but feel free to open a new one if you have any other questions.
Thanks!
