A method measures performance for computing entities being run concurrently. A tool manager samples usage of a computing resource associated with a computing entity. A first state is determined based on the usage. Then, the tool manager determines that an application running in the computing entity started execution of a test that is being run in the plurality of computing entities when the usage changes from the first state. Upon determining the change, the tool manager sends a start command to a performance measurement tool that is configured to measure the performance of the computing entity. The tool manager determines the computing entity is in a second state based on the usage and determines the application ended execution of the test when the usage changes from the second state. Upon determining the change, the tool manager sends a stop command to the performance measurement tool.
