What are you hoping to find out? Do you mean monitoring the performance of the server with concurrent trusted authentication users? Russell Christopher would any of our tools help with this?
We have usage quota for each site. The quota is determined by number of concurrent users per site.
Example - For single core server, the concurrent users is 100. So for 4 sites it comes down 25 concurrent users/site ( equally shared usage). But with trusted authentication from entire web server (using particular Tableau server account), how do you determine the concurrent users for the sites using trusted authentication.
