psmon is a Perl script which can be run as a
stand-alone program or a fully functional
background daemon, capable of logging to syslog
with customisable email notification facilities.
The user defines a set of rules in an Apache-style
plain text configuration file. These rules
describe what processes should always be running
on the system, and any limitations on concurrent
instances, TTL, and maximum CPU/memory usage of
processes. psmon scans the UNIX process table and,
using the set of rules defined in the
configuration file, will respawn any dead
processes, and slay or "deal with" any aggressive
or illegal processes.
