Performance Tools concepts

Describes a variety of tools to help you collect and analyze performance information. Find detailed information about exactly which tools perform which functions and how they work.

The Performance Tools for iSeries™ licensed program analyzes two distinct types of performance data: sample data and trace data. Collection Services collects sample data, which is summary data that is captured at regular time intervals. You collect sample data for trend analysis and performance analysis. The data relates to things such as storage pools and response times. However, Collection Services does not support the collection of trace data. Trace data is detailed data that you collect to gain additional information about specific jobs and transactions. To collect trace data, you can use either the Start Performance Trace (STRPFRTRC) command or performance explorer.
