Performance Tools includes a variety of applications for collecting, analyzing, and reporting performance data. Knowing which functions are available, and which are best suited for a given task can be complex. This topic describes the functions included in this licensed program.
Performance Tools includes reports, interactive commands, and other functions. For example, Performance Tools includes the following:
| Tool | Description |
|---|---|
| Work with System Activity (WRKSYSACT) command | The Work with System Activity (WRKSYSACT) command allows you to work interactively with the jobs, threads and tasks currently running in the system. The WRKSYSACT command reports system resource utilization, including CPU utilization on a per-task basis for partitions that use a shared processing pool. |
| Display Performance Data | The Display Performance Data graphical user interface allows you to view performance data, summarize the data into reports, display graphs to show trends, and analyze the details of your system performance all from within iSeries™ Navigator. |
| Reports |  The reports organize Collection Services performance data
and trace data in a logical and useful format. The reports are discussed in
detail in the Performance Tools book. |
| Graphics function | The Performance Tools graphics function allows you to work with performance data in a graphical format. You can display the graphs interactively, or you can print, plot, or save the data to a graphics data format (GDF) file for use by other utilities. This tool is discussed in detail in the Performance Tools book. |
| Performance explorer | Performance explorer is a data collection tool that helps you identify the causes of performance problems that cannot be identified by sample data that was collected by Collection Services or by doing general trend analysis. Use performance explorer for detailed application analysis at a program, procedure, module, or method level. For example, you can collect trace data on an individual program or procedure CPU and I/O statistics or individual object I/O characteristics. This tool is discussed in detail in the Performance Tools book. |
