Re: Shell script output in monit alert

[Martin Pala]

You can implement the same functionality in the script ... when the script is 
executed, create some statefile at the end of the script (e.g. using 
"/usr/bin/touch /tmp/notification_sent") and make the script skip the 
notification if that statefile exists (next time it is executed). You can embed 
removal of the statefile on recovery event so the next time the service 
recovered and fails again, you'll be notified again.

Something like this:

  if failed ... then exec "/usr/local/bin/myscript" else if succeeded then exec 
"/bin/rm -f /tmp/notification_sent"
