I used a wide range of alerting methods. The most reliable that I have
found (at least for Cingular/AT&T phones) has been TAP. Since this way the
monitoring server can have its own dedicated modem / phone line (separate
from the PBX). Thereby you no longer have to use any of the monitored
equipment to relay failures notifications (i.e. chicken and the egg).
Because a TAP solution is total separate, one thing we had to do was a daily
"test page". Basically every day at noon, a fake check would get tripped on
the monitoring system and send an alert to some of the folks that maintained
the monitoring server. This way if there was a breakdown in the monitoring
system they would (hopefully) notice that they did not get the daily page
and fix the problem.

Subject: Using Mobile Phone email addys for monitoring
Hello folks,
First off, apologies if this is off topic. I'm hoping that system and
network monitoring tip are enough of a common issue that this falls under
the group's charter.
We've traditionally used mobile phone email addresses for system
notifications, but over the past 6-12 months, it seems to have become
increasingly sketchy.
For instance, if an application fails to contact a certain service on a
certain server, it sends an email (through it's own SMTP service, to avoid
a chicken-and-egg prob if/when our main SMTP service fails) to
1234567890@tmomail.net. (Obviously, that was a fake number.) More and
more, I'm getting less and less of these notifications.
It seems especially prevalent when MANY things are sent at once; if, for
example, a central piece fails, and dependent pieces suddenly fail as
well.
I try to telnet to mailx.tmomail.net port 25 and get sometimes good,
sometimes laggy, and sometimes no response. T-Mobile, support levels all
the way up to 3 tell me that it's not them, and everything should work
wonderfully.
Is SMTP to a mobile phone a fundamentally flawed way to do this?
Anyone else have any issues, past or present, with this kind of thing?
Thanks,
Rick Kunkel
