What exactly are you wanting to monitor? Bind some more IPs to the NICs, if you haven't already, and use perfmon from another machine and monitor them
remotey for what you want, or you can use LogParser to analyze the logs for each server. A number of people use WebTrends to do this. As far as
HTTPmon, I don't have an answer for you.

Thank you. I hope this information is helpful.

You could create an extra site on each server (bound to=20

I knew I couldn't be the only one confused by this! I agree that the
259651 doc is inadequate, but all attempts at finding HTTPMon info
seem to lead directly to that dead-end. I was pulled away from this
project recently, but will be returning to it next week. My next
plan: since we only host one web site on these load balanced servers,
I'm going to switch the IP address in IIS properties to <all
unassigned>. That way it will respond to both the cluster IP and the
dedicated IP. If it works, I'll be able to monitor the site I'm
actually concerned about rather than creating a second web site,
binding it to the dedicated IP, and monitoring it to tell me if IIS
goes down. There are docs that say not to use <all unassigned> on a
load balanced web, but they do not explain why. Fortunately I've got
a test lab for this now, so if that doesn't work I can start adding
nics or doing whatever else may be necessary to figure it out.

Please respond if you learn anything new.

Thanks,
Chris
