Filtering data

You can limit the amount of data to be processed by filtering the input data. You can specify filters in the GLOBAL command and in the REDUCE, REPORT, TRACE, and FILE subcommands.

Specify the filters in GLOBAL whenever you can, because only the data that passes through the GLOBAL filters is processed further. The less data OMEGAMON for Db2 Performance Expert needs to process, the better the performance.

However, ensure that you do not exclude records that are needed in OMEGAMON for Db2 Performance Expert processing.
