I do this adhoc reporting with top remotely/centrally using ssh
shared key files (no pw prompt on command line). I've never taken
the next step that you suggest of automating the page. I go look when
I'm looking for trouble. Seems like an easy tcl/perl/cron to review
and move the files around is in order.
If you have snmp based enterprise monitoring in place, it could/should
be done there also. We use Smarts/InCharge for this, which is this
side of wonderful.
