ABSTRACT:
A system for measuring and analyzing operation of an information processor which measures an interval of occurrences of a software event as a measuring object in a measuring object information processor by using a measuring and analyzing information processor. The measuring object information processor outputs data information on a software event, address information of the data information and a write indication signal of the data information and the address information to the measuring and analyzing information processor in response to execution of a predetermined software probe activated by the occurrence of the measuring object software event. The measuring and analyzing information processor alternately writes the data information and the address information together with time information, as measurement data, in a plurality of buffers in response to the write indication signal, as well as reading the measurement data written in the buffers to store the measurement data in a magnetic disk device in time series order.
