Using the System Navigator

Using the System Navigator

Introduction

The EPILOG system navigator helps you investigate bottlenecks easily and quickly. The following is a brief review of some of the basic types of EPILOG displays and how they interact:

Collection Options (O)

This display allows you to determine quickly which workload bottleneck information is being displayed for.

SUMMARY

This display produces a line of output for each interval or multi-interval showing the most significant bottleneck.

DETAIL

This display provides an in-depth breakdown of bottlenecks for a given interval or multi-interval.

Resources (Rccc commands)

These displays contain resource information extracted from RMF and EPILOG data sampling, such as CPU activity, DASD activity, and so on.

Each of these displays can use the collected data at two levels of summarization:

SINGLE

The data is shown either by the RMF interval or by your defined collection interval.

COMBINE

The data for more than one RMF interval is averaged in some meaningful fashion.

Combining these keywords yields the following basic types of panels. Multi-interval summary display. For example: DISPLAY GRP(2) TODAY SUMMARY COMBINE(1H) Multi-interval detail display. For example: DISPLAY GRP(2) TODAY COMBINE STIME(1100) ETIME(1200) Multi-interval resource displays. For example: DISPLAY RCPU TODAY COMBINE STIME(1100) ETIME(1200) Single-interval summary display. For example: DISPLAY GRP(2) TODAY SUMMARY STIME(1100) ETIME(1200) Single-interval detail display. For example: DISPLAY GRP(2) TODAY STIME(1115) ETIME(1130)
