This test tracks various statistics pertaining to the transactions executing on each logical partition of a DB2 database.

Measurement	Description	Measurement Unit	Interpretation
Commit_rate	Indicates the transaction throughput. This measure is the sum of the committed statements attempted on this logical partition and internal commits (total number of commits internally initiated by the database manager) per second.	Commits/Sec	A decrease in this measure during the monitoring period may indicate that the applications are not doing frequent commits. This may lead to problems with logging and data concurrency. The cause has to be probed in the application.
Rollback_rate	Indicates the rate of unit of work rollbacks.	Rollbacks/Sec	A high rollback rate is an indicator of bad performance, since work performed up to the rollback point is wasted. The cause of the rollbacks has to be probed in the application.
Transaction_rate	Indicates the rate of commits and rollbacks for the application using the DB2 Connect gateway.	Transactions/sec	A high transaction rate with high rollback rate indicates bad performance.
