hello,

I am trying to write a generic monitering agent.

There will be some monitoring task for the AGENT_program. This program
(currently) does the reqd check every polling interval. It's basically
doing the monitering in a continous while loop, sleeping the poll_interval
time, for every pass through the loop.

But some things are important enough that I might want an near immidiate
notification rather than at the next poll after the severity of the
monitered
thing changes.

How do I implement such an out of the poll notification ?

I guess, for such a task, the Monitered thing will need to send a 
signal/exception/whatever to my monitering program. My monitering program
will
awaken on reciept of such an event, and make another pass through the while
loop.

I checked, signal()/pause()/exception related stuff, in PY-TUT. But, I don't
know
how to send the messages bet 2 diff programs/processes.

Can someone pl. explain what do I need to do in this case ?

regards,

prasad
