CICS functions for monitoring and gathering performance data

You can use CICS® statistics, monitoring, and trace facilities to gather and monitor performance data to help you tune your CICS system optimally.

CICS statistics

CICS statistics are the simplest and the most important tool to monitor a CICS system permanently. They collect information about the CICS system as a whole, without regard to tasks.

For more information, see Introduction to CICS statistics.

CICS monitoring

CICS monitoring collects data about the performance of all user and CICS transactions during online processing for later offline analysis.

For more information, see Introduction to CICS monitoring.

CICS trace

For the more complex problems that involve system interactions, you can use the CICS trace to record the progress of CICS transactions through the CICS management modules.

CICS trace provides a history of events leading up to a specific situation.

The CICS trace facilities can also be useful for analyzing performance problems such as excessive waiting on events in the system, or constraints resulting from inefficient system setup or application program design.

For more information, see CICS trace.
