We have a ASP Classic Web site Running on IIS 6. What is the cleanest way to record the number concurrent users? We need this data over a period of time, and a way to sum it across servers would be great. What do you suggest?
The Web Services object in Performance Monitor has counters for number of current connections (and some others that might be useful - current anonymous users, current nonanonymous users, anonymous users/sec, etc.). You could setup the counters, then pull the data from each server into Excel to combine and analyze.
