I'm not sure why you'd use mon as a 'local watchdog'.  Mon is quite
capable of monitoring remote machines.  I've used mon for years and it
works great.  It's a simple task to add new monitors for silly things
(silliest one I've done is to check if HP OpenView was still running...)
and monitor everything from status of PRI's to ssh running on remote
machines to whether the news spool is full...

With the 2 CGI's (monshow and mon.cgi) you get pretty web pages.  If you
want graphs, use mrtg -- it's even possible to embed the mrtg graphs into
the monshow 'details' pages.

Between mon and mrtg, you pretty much have it all, and it's easy to
access from a web browser.
