z/TPF software profiler

The z/TPF software profiler is a performance measurement tool that collects and analyzes data for external interrupt (EI) analysis, ECB entry analysis (EA), macro analysis (MA), page range (PR) analysis, and resource consumption (RC).

The z/TPF software profiler consists of two components:

An online z/TPF software profiler command called ZTRAP, which collects performance data by taking samples at timed intervals and writing the data to a file system file or tape for offline processing.
A z/TPF software profiler offline program that selects data runs from the file system file or tape and reduces, formats, and reports the data based on the control option information that you specify to the offline program.
