Enable the cleanup threshold on NV for Load Generator

The NV cleanup threshold is a mechanism for deleting NV packet lists saved on the NV for Load Generator to free up disk space.

Test results are saved in the NV for Load Generator's Data folder, as defined during setup. The Data folder is located by default in \%programdata%\HPE\NV\Emulation\Runs.

When starting a test, if the defined free disk threshold on the NV for Load Generator isn't met, the test results folders will be deleted one by one from the oldest until the threshold is restored, or until only two folders are left. If only two folders are left and the threshold wasn't restored and the test does not start on the Load Generator, consider deleting unnecessary data or reducing the threshold.

The cleanup threshold is 3 times that of the packet list size that is defined on the NV for Load Generator. For details on customizing the packet list size, see Set the default maximum packet list buffer size for each load generator.

By default the cleanup threshold mechanism is disabled. You can enable it on each machine where NV for Load Generator is installed.
