Nagios Support Forum

Hi,
In nagios xi, what email service use to send out email notifications?
We use gmail to send email to notification and here is the configuration.



In our system, we have two nagios xi. One is master and one is slave when both are running. Now what happening is email notification is sending from both server when there is warning or critical. So we want to put email service under HA.

Under the hood you're using PHP to send the E-mail.

There is no builtin way to have a Nagios server failover all the notifications.

Something like this could be achieved by adding the proper check with a custom event handler in your standby server, or alternatively perhaps with a global service dependency.

I think generally Nagios is stable enough and rarely enough has problems of it's own that people find manually enabling notifications on a backup server to be an adequate solution.
