Nagios Alert Emailer

Project Notes

This script is a direct replacement for the basic Nagios emailer. This perl script provides the following features: * Allows you to specify the senders email address * Allows you to specify the destination email address/group * Allows you to differentiate between Host and Service outages * Allows you to connect directly to any SMTP server * Doesn't require any local sendmail configuration * Uses standard Net::SMTP module * Runs within Nagios's embedded perl interpreter * Allows you to format the alert message subject and body * Allows you to send emails to different alert groups based on nagios configuration Configuration steps -------------- I put this in the nagios plugins directory /usr/local/nagios/libexec but you can put it anywhere. commands.cfg --- define command{ command_name notify-by-email command_line $USER1$/send_mail.pl -n "$NOTIFICATIONTYPE$" -h "$HOSTNAME$" -s "$HOSTSTATE$" -a "$HOSTADDRESS$" -i "$HOSTOUTPUT$" -d "$LONGDATETIME$" -e "$CONTACTEMAIL$" } define command{ command_name host-notify-by-email command_line $USER1$/send_mail.pl -n "HOST $NOTIFICATIONTYPE$" -h "$HOSTNAME$" -s "$HOSTSTATE$" -a "$HOSTADDRESS$" -i "$HOSTOUTPUT$" -d "$LONGDATETIME$" -e "$CONTACTEMAIL$" } define command{ command_name service-notify-by-email command_line $USER1$/send_mail.pl -n "SERVICE $NOTIFICATIONTYPE$" -h "$HOSTNAME$" -s "$SERVICESTATE$" -a "$HOSTADDRESS$" -i "$SERVICEDESC$ - $SERVICEOUTPUT$ - $SERVICECHECKCOMMAND$" -d "$LONGDATETIME$" -e "$CONTACTEMAIL$" } contacts.cfg --- define contact{ contact_name contact host_notification_commands host-notify-by-email service_notification_commands service-notify-by-email email [email protected] .... rest of contact details .... }
