-| Description | Add CPU pressure up to the specified value on the VM where this fault is injected for the duration of the fault action. The artificial CPU pressure is removed at the end of the duration or if the experiment is canceled. On Windows, the "% Processor Utility" performance counter is used at fault start to determine current CPU percentage and this is subtracted from the pressureLevel defined in the fault so that % Processor Utility will hit approximately the pressureLevel defined in the fault parameters. |
