The Sampling Collector

The Sampling Collector is a tool that collects performance behavior information about a program while it is running, then writes the information (called an experiment) to an experiment record file and directory that can be read by the The Performance Analyzer.

Before you can collect data using the Sampling Collector GUI:

• You must compile your program using the -g flag.
• You must load your program into the Sun WorkShop Debugging window.
• You must disable run-time checking.

Performing the following tasks configures the Collector to record the data you want:

• Specifying the Data-Collection Run(s)
• Entering a Path and Name for the Experiment
• Choosing the Data to Collect
• Defining the Sampling Interval

Configuring the Collector does not cause it to collect data. You must also run your program in the Sun WorkShop debugger. See Running Your Program for more information
