Nagios Support Forum

Hi all,

I would like NLS to send a mail alert, if the query is returning a VALUE below the watermark.

example 1:
warning: if less than 10 users are connected, send a warning mail
critical: if 0 users are connected, send critical mail

especially checking the 0 count is extremely important for me.

How can I do that?
Thanks, Andreas

There isn't a way to do this with the current NLS alerting GUI. I've filed a feature request for this (ID 9905).

If you were monitoring a Nagios Log Server query from Nagios XI, you could leverage the negate plugin to accomplish this.
