We use nagios and an asterisk system to do critical notifications.
Nagios is a linux package but it can monitor Windows systems. You can write
a plug-in to do anything you can dream up. The action to take for each
notification is also scriptable. So our nagios system sits in my office and
I have it play different tunes via the PC speaker depending on what
happened.
Nagios also has escalation capabilities so I have it set up to call my cell
phone if some critical system is down for a long time. It uses festival
(create a wav file with a short description of the problem and then calls
my cell phone with the message. So at 3:00 AM, I might get a call with an
electronic voice saying, "DNS is critical".
Someday, I am going to change the bbeeps played through the PC speaker to
start with a couple of notes above the threshold of hearing for humans. And
then I'm going to train my guide dog to do something when he hears those
beeps. So if an alarm happens to go off when someone is in my office, the
dog will do his thing and it will look like he knew something was wrong.
That ought to make a few people scratch their heads.

Subject: Re: [Blind-sysadmins] out of hours notifications?
I use the text message alert system however I would love a better way.
Let me know what you come up with?
Sorry I cant be of more help.
What system are you using to send the alerts?
Are you looking for suggestions on alternative delivery methods or the
authenticity of genuine alerts.
For example, I have a mailbox set up just to receive all waht's up gold
alerts. If anything is down even for a second I get an alert. However it
gives a lot of false posatives. Most alerts are more genuine if the
threshold is set to 5 minutes or something like that. What's up gold also
has dependencies so for example, if a switch goes down and at the same time
all the nodes associated with that switch are unresponsive then WUG sends
the alert for teh switch only.
Feel free to ask if you have any questions.
