[p4] Monitoring

[Shawn Hladky]

We use web monitoring software against p4web.  We already had a web
monitoring infrastructure, so our IT guys got this setup in minutes.  It
doesn't provide any OS/Perforce metrics, but it does alert you of any
outages.

One note on this approach, make sure the URL you hit streams the contents of
some file, and you verify those contents.  I've seen the server get into
some states where other p4web pages load, but there are still problems with
Perforce.
