Requesting a summary of the daily or volume statistics

You specify REPORT DAILY FUNCTION SUMMARY to get the summary totals of the daily statistics for all functions. You specify REPORT VOLUME FUNCTION SUMMARY to get the summary totals of the volume statistics for all volumes and all functions. You specify the VOLUMES parameter with a volume serial number to get summary statistics for only one volume. If you request a summary of specified functions, the summary contains the statistics totals for only the specified functions.

When you specify SUMMARY, you get only the summary report. If you do not specify SUMMARY, you get the statistics report you requested and a summary at the end of the report if DFSMShsm reports the statistics for more than one day. A sample of the summary statistics report is not shown because the information is in the same format as the summary information shown in Figure 1 and Figure 1.

Note: For an equivalent time period, it is possible that the number of data sets reported by the REPORT VOLUME command and the number of data sets reported by the REPORT DAILY command will not be the same on the summary page, under the heading "Number Datasets". Some functions (such as MIGRATION, RECALL, BACKUP, RECOVER, and SPILL) involve two volumes, while other functions do not. As each volume counts each data set action, some data set actions will be counted more than once.
