The Performance Analyzer Tool

The Performance Analyzer is a graphical data-analysis tool that analyzes performance data collected by the Collector. The Collector can be started from a Performance Analyzer menu option, or by using the collect command, or the collector commands in dbx. The Collector gathers performance information to create an experiment during the execution of a process, as described in Chapter 3, Collecting Performance Data. The Performance Analyzer reads in such experiments, analyzes the data, and displays the data in tabular and graphical displays. A command-line tool, the er_print utility, is also available for displaying the experiment data in ASCII text form. See Chapter 5, The er_print Command Line Performance Analysis Tool for more information.
