The Sysplex XCF Channel Activity report allows you to track
the utilization of the XCF channels linking multiple systems
through the coupling facility. A sample report is shown in
Figure 2-213.
REPORT OPTIONS
The Sysplex XCF Channel Activity report supports standard
time selection options, as well as SYSID and/or XCF System
selection. These selection options are discussed in
Sections 2.8.5 and 2.8.5.4.
DATA ELEMENTS
The elements reported are divided into two categories:
o Channel Requests
o CF Channels
CHANNEL REQUESTS
The Channel Requests elements describe the level of
request activity occurring on the reported coupling facility
from the perspective of the reporting system (that is, as
recorded by RMF running on the reporting system).
TOTAL The total number of XCF Channel requests
REQUESTS: from the reported system to the coupling
facility during the time period shown:
CFPTOREQ
TOT The total number of unsuccessful XCF
UNSUCCESSFUL Channel requests from the reported system
REQS: to the coupling facility during the time period
shown: CFPTOURQ
REQUESTS/ The average number of requests per second from
SECOND: the reported system to the coupling facility
during the time period shown: CFPPSREQ
UNSUCCESS The average number of unsuccessful requests per
REQS/SECOND: second from the reported system to the coupling
facility during the time period shown. This is
calculated as CFPTOURQ/DURATION.
AVG UNSUC The average service time, in microseconds,
REQS SVC TM: spent during the reported time period servicing
unsuccessful requests.
CF CHANNELS
These elements display path and subchannel availability
measures. These items should be relatively static from one
time period to the next unless some sort of reconfiguration
activity has occured.
AVG PATHS The average number of paths available to the
AVAILABLE: coupling facility during the reported period:
CFPAVPTH.
AVG The average number of subchannels that are
SUBCHANNEL available for use during the reported period:
LIMIT: CFPAVSCL
AVG The average number of subchannels defined (via
SUBCHANNELS the IOGEN) during the reported time period:
DEF: CFPAVSCG.
AVG The average number of subchannels that are
SUBCHANS actually in use during the reported period:
IN USE: CFPAVSCU.
