Log Monitor Recommendations Requested

Hi all,

Sorry if this question isn't appropriate for this list, but I thought
someone here might have some input on my situation.

I'm looking for a Linux application that can watch multiple Conserver logs
and start processes when detecting certain events.  There are multiple
applications available that will send emails based on log events, but I seem
to be having difficulty finding one that will fire off
shell/perl/python/expect scripts.

My situation is this, I need to fill-up a dozen racks with 16 or so units
each.  When a unit is powered on, I need to automatically open a console
connection to it, configure it to boot from NFS, run a series of tests,
install an O/S and shut it down.  The only interface into these units is
through a serial console port.  My thought is to use a log monitor program
to watch the conserver logs for the unit boot notifications and then use a
script to open the conserver client and interact with the unit.
Unfortunately, I can't seem to locate a log watch tool that can watch
multiple logs and then trigger a (non-email related) process.

Any help would be greatly appreciated.

Scott
