Collecting input data for group-scope reports

To produce group-scope reports, you need input data from all members of a group.

For regular monitoring, you most likely collect the performance data into SMF data sets. If all Db2 subsystems of the data sharing groups reside in the same OS/390® system, you can collect the data to one SMF data set. If the members of the group reside on different OS/390 systems, you have to concatenate the SMF data sets from all OS/390 systems before you can use the data as input for group-scope reports.

Similarly, if you have collected instrumentation data for the individual members in separate data sets (GTF data sets or data sets created by collected report data), you can concatenate these data sets to generate group-scope reports.
