Monit is testing for service health. Any error condition has associated 
appropriate event type. One of tests is "existence" test, which equals 
to "crash" event in the case of process under exclusive monit's control.

Start, stop and restart are just actions evaluated by monit - it makes 
no sense to test for it - they are connected to the event. Monit reports 
the <event> and <action> in progress together.

In the case that the service is not controled by monit, you need to 
manage its start/stop/restart events outside of monit. In such case 
Monit only knows that the service is running or not running - the reason 
why it for example doesn't exist is not available to monit (was it 
externaly stopped or crashed?)
