simple HTML email alert Template for Icinga 2 to replace the default boring text based email alert.
Update: I have replaced mail command with mutt due to incompatibility of options among different linux distributions. Also I have added new color highlight feature for different states (ok=green,warning=orange and critical=red).
Take backup of existing files in /etc/icinga2/scripts and copy this new scripts to it
Edit the "Variables for HTML Template" section in mail-service-notification.sh
SUBJECT="$SERVICEDISPLAYNAME $SERVICESTATE! - $HOSTDISPLAYNAME"
TITLE="Icinga Server Monitoring"
