Flash Comm Failure 2004-03-10 - By Brian Lesser

Hi Chris,
LOL.... Yeah, I can make sure your name gets in there... but you really
don't have to buy ten copies. :-)
Regarding monitoring, you would only use it as an add-in on top of other
regular performance monitoring tools. Our tech support staff have a
system that aside from monitoring server processes, free memory, cpu
load, etc also generates alerts including paging them any time something
really bad happens. I wrote a simple app that uses setInterval to run a
sequence of tests. Basically it just opens a NetConnection to a simple
test application on the production server every few minutes. Just like
one instance can open a netconnection to another instance on the same
box in the lobby/rooms thing. Except instead of localhost you have the
name of the production system in the address you feed nc.connect. Once
the test app makes the connection it just sends a message back and forth
to do a very basic health check If it finds anything wrong it simply
calls a CFC on one of our Coldfusion boxes that sends a message to the
tech support monitoring system. A lot of the monitoring systems will
accept an email alert. In that case you can use a cfmail tag to send the
alert.
In summary you have:
a test app on the production server that only allows connections from
your test box
a different test app on your monitoring box that connects to your
production test app every few minutes..
Now that is a very limited health test but is better than just checking
if a port is active or if you still have memory on your machine. Even
better would be to hook into the admin api.
Cheers,
-B
