Re: Another feature

[Martin Pala]

Yes, the alert action implementation handles the notification so, that the 
alert is sent only on state changes (success->failure or failure->success). 
There is a 'reminder' option which allows to repeat the alert if the service 
remains in error, but by default it sends one alert only.

If you delegate the alert to script via exec action, it will be executed on 
every failure cycle (monit tries to recover the service and unless timeout 
statement is used, it calls the exec action each time). In order to reach the 
same alert-on-state-change functionality, you'll need to do it in the executed 
script.

Martin
