Critical Audible Alarms with Unreachable Hosts

[Scott Smith]

That is a possibility (only enabling the Host Down sounds).  We like
having the sounds for Critical and Warnings as well.  Otherwise the NOC
typically will not look at the Nagios webpage.  Hence why they stated
the Sound was just 'so' important to them.

If all the devices are Acked then there are no sounds from the webpage.

I was just thinking that it made sense to me if Nagios knows where the
Network Outage is, and is smart enough to only send one Notification,
then why doesn't it do the same thing on the webpage sounds?  It appears
to me that the same intelligence isn't transversed to the CGI's.  At
least that's my opinion at this point, I can't seem to find any solid
answer on this question yet.
