This report produces a tabular listing of channel activity by CHPID for the duration of the period specified in the run- time execution parameters. The percent busy and the percent of system values represent an average for the period covered by report. INTENDED USE: Allows analysis of CHPIDs that are being heavily used. Such a report might be used to detect channels that are being over-utilized or under-utilized, and to detect the proportionate share of all channel activity being handled by a given channel. FORMAT: A tabular report in ascending order of CHPID, where each column represents a different measurement associated with a given CHPID. An example of this report is shown in Figure 3-4. INQUIRY ID: Tabular Report: VMXTX2 DATA SOURCE (File/Timespan): VMXCHC01 - DETAIL DATA ELEMENTS USED: CHCHPID - Channel Path ID VMXHFSAM - High Frequency Sample Count CHCPCBSY - Percent CHPID Busy CALCULATIONS: SYSBUSY, the percentage of all channel activity handled by a given channel, is obtained by adding up the summarized percent channel busy values for all CHPIDs, and placing this value in a temporary element named BUSYTOT. The percentage workload held by each channel path is then computed as follows: SYSBUSY = CHCPCBSY / BUSYTOT*100; USAGE CONSIDERATIONS: The Channel Path Contention Data File (VMXCHC) is created from the 0/09 monitor records. With the introduction of z990 processor, the 0/09 no longer contains valid channel path information. It is recommended that the 0/18 or 0/20 monitor records be used for valid channel path information. See report VMXLS1 (VM Channel Path Load Analysis).
