One of the Google groups that I monitor pretty closely posted a question about finding out "accurately" the number of active sessions on a web application.

In poking around MSDN I found the following two articles that will come in extremely handy in the future.

The first is on Asp.Net Performance counters and can be found here.

The other involves source code for a web service that exposes these performance counters - now that's handy code...

Awesome stuff...

I plan to modify the code from the web service example to allow me to specify what server I want to read from so that I can make a vitals monitor "client" on my website...
