Is it flawed? It depends on your business requirements. If seconds,
milliseconds, or even microseconds matter to your mission critical apps
(think real-time trading networks) then you would want a 24x7 staffed
NOC using an enterpise monitoring system - something like Openview. You
wouldn't want to rely on anything that sends emails. =20

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
