This chapter describes the trace collection points and PRF trace collection levels of the following trace based performance analysis.

• Trace collection points and PRF trace collection levels output for each function layer by the trace based performance analysis

When a request is sent from the Web client or the EJB client, the Web server, J2EE server, and CTM output the trace information at the point (trace acquisition point) of some specified processes. Furthermore, in the trace based performance analysis, the trace can be output by setting up the PRF trace collection level, such as Standard and Advanced.

• Trace collection points and PRF trace collection levels output for each method forming the starting point of application processing by the user-extended trace based performance analysis
  In the user-extended trace based performance analysis, by specifying a method that forms the starting point of application processing as the processing point for acquiring the application performance analysis information, you can output the trace at the point when that method is called.
