Performance Reporting

Performance Reporting

Introduction

You can use EPILOG for basic performance reporting tasks. All EPILOG displays are available both interactively (under TSO) and in batch. Under TSO the reporter takes advantage of the full-screencapabilities of an IBM® 3270 family terminal; it provides scrolling and highlighting of important information. Extended color support is available with 3279s that have this feature.

You can request EPILOG information panels using simple yet powerful commands. For example, the command

DISPLAY SUMMARY GRP(3) STIME(10) ETIME(12) SDATE(01/02/97) EDATE(01/02/97)

results in the following display:

The report above shows the main IMS wait reason for PSB Group 3 for each 15-minute interval during the day. For instance, for the 10:45-s11:00 period, the main IMS wait reason was the database DB PMFG021.

There are four basic EPILOG displays: Summary display (Figure 2 on page 28).

Detailed bottleneck display which divides a thread into its component execution states and wait reasons (see Figure 8 on page 66).
