2.4.8.1 Standard Output

FICON Channel Performance Analysis provides a simple graphic
and a series of summary and detail level reports that display
both performance and resource usage metrics.  Examples of
each are included in this section.

The Processor Complex & Channel Configuration report provides
a listing of all CECs, LPARs and related FICON channel
definitions for the input data.  This report can be used to
determine the identity of the CECs for later use in data
filtering and to better understand which channels are both
defined and active on their respective LPARs.

The Channel Service Time graphs are produced for each
selected channel and provide a visual analysis of channel
service time versus both Open Exchanges and Credits.  This
permits the analyst to quickly understand the macro-level
performance of each channel and to determine if any specific
problem areas exist.

The Channel Resource Summary Usage report is used to
summarize all performance and resource measurements for each
selected channel across the specified time intervals, and
additionally to demonstrate the contribution of each LPAR to
the overall channel workload. This format allows the analyst
to understand the overall performance of each channel and how
each LPAR affects the channel performance. A typical use of
this report would be to first identify one or more peak times
and then execute this report, selecting those time intervals
as a follow on to the Channel Service Time graphs discussed
above.

The Channel Resource Usage Detail report produces a composite
of performance and resource data for each RMF interval for
each selected channel.  This report can be used to identify
periods where a channel is performing poorly.

The sample output below is printed at the beginning of each
of the reports and graphs, and depicts the data selection
criteria that was specified during query composition.  The
categories are common to most of the Performance Management
product and are not discussed in detail here.

The CEC (Processor Complex) entry refers to the serial number
of up to six processor complexes to be selected.  The
Channels entry is a list of up to eight channels to be
selected.

Leaving an entry blank results in a default selection of
"ALL", indicating that no filtering is being performed.
