[hobbit] Is there a way to "quietly" disable hosts that have NOTICE set?

[Charles Jones]

Okay, let me explain this again :)

If I ignore pages for a specific time interval, say 2 hours while 
backups are being done, then every minute that the backups complete 
before that interval is over, is a minute that the database is 
essentially not monitored, which is not acceptable.

Example:

via DOWNTIME in bb-hosts, or via TIME specifications in 
hobbit-alerts.cfg as you mention,
[----------window where no pages are sent for red status of "oracle" or 
"procs"------------]
[-----------------database backups--------------][------ something can 
break here -------]

My problem is that something can break during that post-backup interval, 
and nobody will be notified. Making the interval shorter is not an 
option because due to the nature of backups, the amount of time it takes 
to do the backup fluctuates on a daily basis. It could take 30 minutes 
monday night, an hour tuesday night, 10 minutes wednesday night, 73 
minutes thurs.. Using the bb disable command from a script is not a good 
solution because that makes NOTICE alerts get sent out, which wakes 
people up for no reason.

The DOWNTIME option in bb-hosts has the ability to set the status of 
services blue without sending NOTICE alerts. I would like this same 
ability on an interactive basis (via a message to hobbit using the bb 
command).
