Performance Collector APIs

This section discusses the AS/400 performance collector APIs and exit program.

The APIs are presented here in alphabetical order and are followed by the exit program.

The performance collector APIs are:

List Performance Data (QPMLPFRD) returns data from the data collector to the user space specified in the Work with Collector API.
Work with Collector (QPMWKCOL) controls the starting and stopping of collections of information for certain types of resources. This API allows you to change the way data about a certain resource is collected.

Note:

The Work with Collector API must be used before using the List Performance Data API.

Performance Collector Exit Program

Performance Monitor exit program: processes the performance data that is collected by the performance monitor as the monitor ends.
