Email Notification Setting
It is enabled on some items by default but if you wants to change it, configure like follows.
- Install and start SMTP Server
- Set notification recipient. And Nagios sends notifications with mail command, so install it.
- It is possible to change notification setting on Nagios admin site.
# yum –y install mailx
# vi /etc/Nagios/objects/contacts.cfg
# line 34: set recipient email address
# systemctl restart Nagios
