Requesting a report of the daily statistics for all functions

You specify REPORT DAILY to get a report of the daily statistics. Table 1 shows the output headings for the daily statistics report.

Note: If you specify selected functions such as REPORT DAILY FUNCTION BACKUP or REPORT DAILY FUNCTION RECOVER, then line 5 is output only if BACKUP is requested and line 6 is output only if RECOVER is requested.

DAILY STATISTICS REPORT
FOR YY/MM/DD

 When you specify REPORT DAILY, this line contains today's date. When you specify REPORT DAILY FROMDATE(yyyy/mm/dd) TODATE(yyyy/mm/dd), this line contains the first date you specify. DFSMShsm reports all statistics for the first date, then reports the daily statistics for the second day, and so forth.
2 STARTUPS=xxx This field shows how many times DFSMShsm was started on the specified day.
2 SHUTDOWNS=xxx This field shows how many times DFSMShsm was stopped on the specified day.
2 ABENDS=xxx This field shows how many times DFSMShsm abnormally ended for the specified day.
2 WORK ELEMENTS PROCESSED=xxxxxx This field shows how many management work elements DFSMShsm processed for the specified day. If DFSMShsm is reporting daily statistics for all functions, this field means how many management work elements DFSMShsm processed.
2 BKUP VOL RECYCLED=xxxxx This field shows how many tape backup volumes DFSMShsm recycled for the specified day.

6 xxxxx FAILED This field shows how many of the full-volume restores failed.
6

DATASET RESTORES =

9 FAST REPLICATION VOLUME BACKUP=xxxxxxxx REQUESTED, xxxxxxxx FAILED This field shows the number of fast replication backup versions that were requested and how many of the fast replication backups failed.
10 FAST REPLICATION VOLUME RECOVER=xxxxxxxx REQUESTED, xxxxxxxx FAILED This field shows the number of fast replication recoveries that were requested and how many of the fast replication recoveries failed.
11 DATA SET CLASS TRANSITION=xxxxxxxx REQUESTED, xxxxxxxx FAILED This field shows the number of class transitions that were requested and how many of the class transitions failed.
12 and 13 HSM FUNCTION This field contains the names of the functions DFSMShsm processed. When you specify REPORT DAILY FUNCTION, DFSMShsm reports the daily statistics in the following order:
  1. MIGRATION

    The category SUBSEQUENT MIGS reflects all movements of data sets from ML1 to ML1, ML1 to ML2, and ML2 to ML2. This includes FREEVOL moves but does not include RECYCLE moves. The PRIMARY to LEVEL2 category includes data set migrations by reconnection.

  2. RECALL
  3. DELETE

    Deletion of migrated data sets include only those deleted by the DELETEBYAGE (DBA) or DELETEBACKEDUP (DBU) functions from migration volumes, generation data sets that have been rolled-off from migration volumes, and migrated data sets that have expired by date or MCLASS attributes.

    Deletion of primary data sets include only those deleted by the DELETEBYAGE (DBA) or DELETEBACKEDUP (DBU) functions, generation data sets that have been rolled-off from primary volumes, and primary data sets that have expired by date or MCLASS attributes.

    The DBA and DBU functions apply only to non-SMS data sets.

  4. BACKUP
    SUBSEQUENT BACKUP results from command backup, daily backup, FREEVOL processing and is the combined total of the following:
    • Data sets moved from backup volumes to spill volumes
    • Data sets moved from ML1 volumes to backup volumes
    DELETE BACKUP results from command backup, daily backup, BDELETE and EXPIREBV processing and is the combined total of the following:
    • Backup volumes deleted after DFSMShsm processes the EXPIREBV command
    • Deletion of excessive incremental backups
    • Data sets deleted after DFSMShsm processes the BDELETE command
  5. RECOVER
  6. RECYCLE
  7. CLASS TRANSITION

You can also choose to ask DFSMShsm to report statistics for specific DFSMShsm functions. For example, when you specify REPORT DAILY FUNCTION RECYCLE(ALL), DFSMShsm prints a daily statistics report of the number of tape backup and ML2 volumes DFSMShsm recycled during the time period you specified.

Note: MIGRATION and RECALL statistics do not include amounts for extent reductions.
12 and 13 NUMBER DATASETS This field shows how many data sets DFSMShsm processed for each function.
12 and 13

      ------READ------
TRK/BLK   BYTES

 This field shows how many tracks or blocks DFSMShsm read when processing the specific function. For data movement involving DASD, the first part of the field contains the number of tracks. For recycle, the first part of the field contains the number of 16K tape blocks. The last part of the field contains the number of kilobytes DFSMShsm read when processing the specific function.
12 and 13

     -----WRITTEN-----
TRK/BLK   BYTES

 This field shows how many tracks or blocks DFSMShsm wrote when processing the specific DFSMShsm function. For data movement involving DASD, the first part of the field contains the number of tracks. For recycle, the first part of the field contains the number of 16K tape blocks. The last part of the field contains the number of kilobytes DFSMShsm wrote when processing the specific function.
12 and 13

       -----REQUESTS-----
SYSTEM  USER  FAILED

 This field shows how many requests came from DFSMShsm during its automatic processing, how many came from the user, and how many of the total requests failed.
12 and 13 AVERAGE AGE This field contains the average age of the data sets that each function processed. For the MIGRATION and DELETE functions, this is the age of the average data set since it was last referred to. It is calculated by subtracting the date last referred to from the age of migration and dividing the result by the total number of data sets processed. For the RECALL function, this age is how long the average data set has been migrated. For the BACKUP, SPILL, and RECOVER functions, this age is the last time DFSMShsm made a backup version of the data set. The average age does not apply to the RECYCLE function.
12 and 13

-----AVERAGE TIME-----
QUEUED WAIT PROCESS TOTAL

 This field shows the average time in seconds that the request for each data set was waiting to be processed, the time spent allocating and opening each data set, and the time spent processing each data set. TOTAL shows the average time it took DFSMShsm to process each data set request. For the SUMMARY, the time for each day is accumulated prior to calculating the daily average. The AVERAGE TIME field is the total time for all days divided by the total number of data sets, giving the average time per data set.

If you specify the FROMDATE and TODATE parameters, DFSMShsm prints a summary of all the daily statistics after it prints the daily statistics for each day you specified. If you have requested statistics for specific functions, the report contains statistics for only those functions.

Note: If the letter K, M, G, or T follows any field, then the reported number is represented to the nearest kilobyte (kilotrack), megabyte, gigabyte, or terabyte, respectively. All output will be reported to the smallest possible unit measure. For example: 
    1 KILOBYTE  = 1024 bytes
    1 KILOTRACK = 1024 tracks
    1 MEGABYTE  = 1,048,576 bytes
    1 GIGABYTE  = 1,073,741,824 bytes
    1 TERABYTE  = 1,099,511,627,776 bytes.

   999,945,993,123 will be represented as 976509759K.
   103,999,945,993,123 will be represented as 99182077M.
   112,103,999,945,993,123 will be represented as 104404986G.
   4,112,103,999,945,993,123 will be represented as 3739937T.

The maximum reportable number is 4 611 686 018 427 387 904 or 4194304T. After this value is exceeded, the output reported resets and begins at zero. If it is suspected that this condition exists, rerun the report with a closer specified FROMDATE/TODATE.

Figure 1 is a sample of a daily statistics report that you get when you specify REPORT DAILY FUNCTION FROMDATE(2002/08/19) TODATE(2002/08/20). Therefore, you have the daily statistics for each day and then you have a summary report for the two days.
