The SUT Query option can be enabled within some nodal test cases and can also be used as a standalone test case in any test session. It lets you collect information from the SUT while the test is running: you can periodically sample the SUT's CPU utilization or automatically send a query command via a SSH interface. The results of the CPU sampling are displayed on the Test Summary report tab, and the reply to a query command is displayed in the Test Log.
In addition to monitoring the SUT CPU, you can define dynamic rate adjustments that are triggered when the actual CPU usage is above or below the specified target usage. When the CPU is under the target, the test rates are increased, and when the CPU exceeds the target, the test rates are decreased. Using the dynamic rate adjustment, you can develop a test that determines the rates that can be achieved without placing an intolerable load on the CPU. Dynamic rate adjustment is only available when you use the SUT Query option in a nodal test case.
In addition, you can define parameters for Network Test. Commands available:
In addition, you can define parameters for Measurements Test. Details in SUT Query Test Configuration

NOTE: SUT Query should not be used with a rate test. The additional processing overhead will distort the maximum achievable rates. |
