Stop nagios downtime alert spam

If you're like me and find the nagios alerts declaring when scheduled downtime starts and ends annoying, try wrapping your notify command in an if block:

command_line if [ "$NOTIFICATIONTYPE$" = "PROBLEM" -o "$NOTIFICATIONTYPE$" = "RECOVERY" -o "$NOTIFICATIONTYPE$" = "ACKNOWLEDGEMENT" ]; then /usr/bin/printf "%b" "***** Nagios  *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $DATETIME$\n\nAdditional Info:\n\n$OUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$; fi
