Operation and Maintenance department in the monitoring system, all need to have the mail alarm function, but like the past cacti there is no such function.

The Mail command from Linux allows you to send messages either internally or externally.

How Mail is sent:

1 echo "Mail Content" | Mail-s "Mail Header" receiver address

2 Saving the contents of a message as a file

Mail-s "Mail title" email Address < mail content file

Send mail to System local account:

echo "Root_status" | Mail-s "root" [email protected]

Tail/var/spool/mail/root
