cpu alerts

What time should Hobbit consider the start-of-event time?  Some prefer
the current arrangement where it uses the time it goes non-green; others
prefer the time it goes to a color which triggers an alert.  I've heard
arguments both ways.

Thanks Henrik.  The way it is working in the server I have running
4.2.1RC1is how I'm looking for it to run on the standby server, which
I just
installed 4.2.1P1 on and I'm still getting the alerts with the duration
including the yellow time, not just when it goes to red\panic.  Is there a
way I can change it so that it will work as it does in 4.2.1RC1 and only
send an alert after 10 minutes of  a red panic that doesn't include the
yellow in the duration?  I'm also finding I don't get recovery notices if it
goes from red to yellow and then to green.

Here is the hostname.cpu and section from notifications.log for those

OK, Hobbit thinks the first event begins at 10:34 when the status
goes yellow. Even though this doesn't trigger an alert, it registers
this as the starttime of the event. So when it goes red at 10:54, your
10 minute delay has already elapsed, and you get an immediate alert.
Then when it goes green at 11:04 you of course get a recovery notice.

Same thing when the goes yellow again at 11:09. No alert is sent, but
this time is registered as the start of the event. So at 11:14 when it
goes red you do not get an alert (11:09->11:14 is only 5 minutes), but
you do get the alert at 11:19:30 - and when it goes green at 11:19:31
it sends out a "recovered" message.

What time should Hobbit consider the start-of-event time?  Some prefer
the current arrangement where it uses the time it goes non-green; others
prefer the time it goes to a color which triggers an alert.  I've heard
