While LoadUI NG is running a load test, it collects data on the service performance. You can see the collected data in the Global Metrics graph, in the Test Step Metrics table and on the Statistics page.

The Global Metrics graph shows how various performance metrics of your target web service change over time. Examine the VUs/s (the number of users arriving to the server each second), Time taken (time taken for each request), TPS (transactions per second) and BPS (bytes per second) metrics to find out how your target service performs.

The Test Step Metrics table contains performance values of individual test steps, such as the maximum and minimum time it took to simulate each of them.

To view and check other statistics of your test runs, switch to the Statistics page (you need a LoadUI NG Pro license for this. Feel free to request a trial on our web site).

Tip: You can also configure server monitors and analyze the server metrics on this page.

If you ran several tests, select the needed one from the Run drop-down list. By default, LoadUI NG stores the results of the last 5 runs.

If your test is still running, you will see the statistics updating in real time to reflect new simulated requests.
