Cost analysis for selecting trace objectives

摘要

A tracing system may perform cost analysis to identify burdensome or costly trace objectives. For a burdensome objective, two or more objectives may be created that can be executed independently. The cost analysis may include processing, storage, and network performance factors, which may be budgeted to collect data without undue performance or financial drains on the application under test. A larger objective may be recursively analyzed to break the larger objective into smaller objectives which may be independently deployed.

1. A method performed by a computer processor, said method comprising:
receiving an application to instrument; identifying a first trace objective for said application, said first trace objective comprising a plurality of data items to collect; determining that said first trace objective exceeds a cost threshold; creating a second trace objective comprising a first subset of said plurality of data items and a third trace objective comprising a second subset of said plurality of data items; determining that said second trace objective and said third trace objective are within said cost threshold; causing said second trace objective and said third trace objective to be executed; and collecting said first subset of said data items when said second trace objective is executed and collecting said second subset of said data items when said third trace objective is executed.
