View results

After the test has stopped and results data has been collected, switch to the Results view tab to examine the test data and statistics. There you can view different reports and even some graphs.

The most useful reports and graphs are: Test Summary, Audit Log, Report Log, and Test Error Log HTTP Data List (for debugging HTTP responses) HTTP Response Time (Average per Second) versus Number of Responses Graph

This graph displays the average response time for requests grouped by the number of requests per second during a test run. HTTP Errors versus Active Users Graph

This graph displays the effect on performance measured by the number of HTTP server errors returned as the number of active Virtual Users varies during a test run. HTTP Responses versus Elapsed Time Graph

This graph displays the total number of HTTP responses per second during the test execution. HTTP Response Time versus Elapsed Time Graph

This graph displays the average response time per second of all the requests issued during the test run. Timer Values versus Active Users Graph Timer Values versus Elapsed Time Graph

OpenSTA Commander also provides two additional features to help you with further data analysis: Exporting results data

This feature allows you to export every text-based report into a comma-separated-values (CSV) file. Every graphics report can be exported directly into Microsoft Excel, where you can perform additional statistical calculations. Export the data by right-clicking inside the opened report window, select Export and save the CSV-file or open it inside Excel. URL filtering the report data

This feature is available when right-clicking inside a graphics report and selecting Filter URLs. For example, you can filter out any URLs so that only the servlet request to /trade/scenario is left. Then the graph displays only the response times for the actual dynamic content of your load test.

The most interesting reports are:
