Input for reports
The Db2 trace facility, also called the DB2 instrumentation facility, gathers information about the system. After Db2 has collected and externalized this data, you can use it to generate reports and data sets.
An easy way to prepare a Db2 trace command is to use the Traces function of the Performance Expert Client. You can use this facility to create and manage Db2 traces. You can specify what types of reports you want to produce and how and when the traces should start and stop.
