15. Performance Analysis Trace

The performance analysis trace functionality collects the performance analysis information (trace information) output by each functionality of the application server when the server processes a request from a client, and collects performance analysis information (trace information) output by the application processing.

Based on this information, you can analyze the processing performance of the system and applications. This chapter describes how to analyze performance of the system and applications by using performance analysis traces. The following describes the items that differ between V9 compatibility mode and recommended mode. For information that is not provided in this chapter, see 7. Performance Analysis by Using Trace Based Performance Analysis in the manual uCosminexus Application Server Maintenance and Migration Guide. For details on the points when performance analysis information is collected and the scope of information collection (PRF trace collection levels) by using performance analysis trace, see the sections from 15.5 Overview on trace collection points and PRF trace collection levels of performance analysis trace through 15.13 Trace collection points of CDI.
