Analyzing Load Test Virtual User Activity in the Details View of the Load Test Analyzer

 

Virtual User Activity Chart

Virtual User Activity Chart

The Details view displays the Virtual User Activity Chart, which is used to visually analyze what the individual virtual users did during the load test. Virtual User Activity Chart lets you see patterns of user activity, load patterns, correlate failed or slow tests, and see requests with other virtual user activity. The Virtual User Activity Chart can also help you determine spikes in CPU usage, drops in requests per second, and what tests or pages were running during the spikes and drops.

Requirements

  • Visual Studio Enterprise

Before you run the load test for which you want to use the Virtual User Activity Details Chart, you must verify that the Timing Details Storage property is set to the AllIndividualDetails option by using the Load Performance Test Editor. For more information, see How to: Configure Collecting Full Details to Enable the Virtual User Activity Chart.

Details Legend Panel
