[hobbit] Alerting on "non-green" events of a given duration

[Josh Luthman]

I understand perfectly what you're saying, but what I'm getting at is there
are no differences (in Hobbit's POV) between "the bad "flopping"
red-->yellow-->red-->yellow" and the green -> red -> green of that update
being installed.

Is there a way you can have the server that is updating its spam definitions
call to Hobbit and have it disable the monitoring for the next short while?
How are the spam definitions updated?
