Interpretation and Analysis User Guide

This section is a guide to application performance management (APM) using the StrobeApplication Performance Measurement System, a product designed for use on IBM z/OS systems. It describes the benefits of using Strobeand explains its capabilities. It describes the set of reports that make up the StrobePerformance Profile reports, and presents a guide to interpreting the information shown in the Performance Profile.

How this space is organized

Overview describes the benefits of APM and presents an overview of the Strobesystem.

Interpreting the Strobe Performance Profile presents a general discussion of how to interpret the reports in the Performance Profile and then presents a case study with reports generated from a sample COBOL program.

Strobe Performance Profile describes each report in the StrobePerformance Profile. It explains report terminology and discusses fields within each report.

Program Structure and Strobe Pseudo-Entities presents a sample program structure and discusses the system modules whose activity Strobe compresses to make reports more concise.

Sample Program and Strobe Performance Profile presents a sample COBOL program and the StrobePerformance Profile that resulted from measuring and indexing the program.

How to use this space

To understand the benefits of Strobeand to determine which programs to measure, read Overview before you submit a measurement request. For help in interpreting a StrobePerformance Profile, read Interpreting the Strobe Performance Profile and Strobe Performance Profile.
