The values on the S1-AP tab report the bearer plane processing measurements in a MME Nodal Test Case and the MME Node Test Case.
In the default view, the Reports tab displays the Summary view, which summarizes the measurements for the test session. If your test includes multiple test cases, you can view the report for a single test case by changing the report view...
Unless otherwise noted, cumulative values report the number of occurrences or rates calculated since the start of the test, and per-interval values report the number of occurrences or rates calculated during the interval. You can view either by changing the measurement values...
Elapsed Time is the first measurement on every tab. It reports the amount of time between the start of the test and the end of the report interval.
Test Iteration reports the current iteration in a repeating test session. It is only displayed when a Number of Iterations is defined for the test session.
