PERIODICITY OPTIMIZATION IN AN AUTOMATED TRACING SYSTEM

摘要

Periodicity similarity between two different tracer objectives may be used to identify additional input parameters to sample. The tracer objectives may be individual portions of a large tracer operation, and each of the tracer objectives may have separate set of input objects for which data may be collected. After collecting data for a tracer objective, other tracer objectives with similar periodicities may be identified. The input objects from the other tracer objectives may be added to a tracer objective and the tracer objective may be executed to determine a statistical significance of the newly added objective. An iterative process may traverse multiple input objects until exhausting possible input objects and a statistically significant set of input objects are identified.

1. A method performed by a computer processor, said method comprising:
receiving an application to instrument; performing a preliminary trace of said application while said application executes and collecting preliminary results; analyzing said preliminary results to identify a set of periods within said preliminary results; selecting a first period within said set of periods; identifying a first trace objective for said application, said first trace objective comprising a plurality of data items to collect and a first collection window comprising at least three times said first period; and causing said first trace objective to be executed and collecting a first results set comprising said plurality of data items and a first input stream.
