 What monitoring tools are folks using here?
I have so far found Ergosol's Watchdog - it provides a neat solution to 
high-level server security, status and connectivity monitoring with 
email alerts. I tweaked it a little for adjusting it to OpenVMS 7.3 - 
you can grab it from 
http://sanyal.duckdns.org:81/pub/rampage.sav
I am getting (NUMEROUS!) emails from all intrusion attempts and whenever 
someone logs in to the monitored accounts, as well as when any of the 
monitored HECnet nodes or internet IPs are unreachable.

Intruder Alert product, emails -- such as provided by your Watchdog -- will
soon overwhelm you and you'll soon either ignore them, or supress them, or
sequester them for review well after the fact.
