We want a high performance testing tool for a distributed scenario
We want to collect data from clients and from server (memory usage, cpu usage, response time, .net calls etc).
Most of our applications are using .Net 4.0 or Classic Asp.
We have 4 servers. We want 1 controller and three agents working together for testing, collecting data.
What's the best tool for this scenario?
ps: We've tried Visual studio 2012 ultimate and it seems promising. I don't know other tools that fits the scenario.
