I imagine that Brian needs this "AW health flag" available in a CP logic.
You can use an existing OM variable: once linked to a LOGIC/CALC input, you
apply the RQL statement to this input; the result=TRUE means an healthy
connection to AW.
It's robust enough? Any concern?

Building on what Terry said, I'd put a heart beat in the variable. Write a
script that runs under cron (or XP scheduler) to set/reset (or increment with
wrap) the OM variable.
If you can get the value and its changing, things must be pretty reasonable.
As for the System Monitor, there's a series of programs that do the monitoring
and the data is not generally available. There are some utilities that make
some of it available to scripts, but that wouldn't really meet your need.

Jack,
Sometimes "ping" does not work even when you are up and running. You might be
better off to create a shared variable on boot up and do an omgetimp of that
variable. If it returns a value without error, your AW is running and connected
to the node.

Although rather rude and crude, I have used a test for ping success in
scripts to verify an AW was up and running before performing some remote
operation to or on it.
