nagios:: notify-by-email.sh

Requirement:

I want to know who acknowledged a nagios alert I've just received. 

Here's how,

Copy this script to your nagios plugins directory,

• send-by-email.sh
• script must be executable (# chmod 755 send-by-email.sh)

Then make sure you specify this file under your nagios configuration, under the commands file or section of you configuration (depends on how your nagios is setup)

define command{
        command_name    notify-by-email
        command_line   /usr/lib64/nagios/plugins/notify-by-email.sh $NOTIFICATIONTYPE$ "$SERVICEDESC$" "$HOSTALIAS$" "$HOSTADDRESS$" "$SERVICESTATE$" "$SERVICEDURATION$" "$LONGDATETIME$" "$SERVICEOUTPUT$" "$CONTACTEMAIL$" "$NOTIFICATIONAUTHOR$" "$NOTIFICATIONCOMMENT$" 
        }

Then under your contacts set the service_notification_commands to notify-by-email as example below,

define contact{
use generic-contact
name email-only
service_notification_commands   notify-by-email
~ truncated ~
}

Enjoy! Remember this is just a quick overview of how to. If you have any question regarding your nagios installation, then please ask.

Cheers,
