RESPONSE DELAY ANALYSIS SYSTEM AND RESPONSE DELAY ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a response delay analysis system realizing efficiency of identification work of a response delay cause of a real time task, and further to provide a response delay analysis method.SOLUTION: A response delay analysis system comprises: trace log analysis means; and trace point resetting means. The trace log analysis means analyzes a plurality of trace logs acquired by executing a real time task a plurality of times under conditions of a trace point being set and determines a processing block being a cause of a response delay. The trace point resetting means resets the trace point with the processing block determined as a trace object such that the plurality of trace logs is acquired at finer granularity. The response delay analysis system recursively executes execution of the real time task, analysis of the trace logs and resetting of the trace point until the processing block being the cause of the response delay is identified at minimum limited granularity.
