The z/OS workload manager (WLM) and CICS monitoring facility (CMF)

Managing and monitoring your CICS® workload is important to help you to achieve performance goals.

Workload management is the process of defining performance goals for the items of work in a system (such as a z/OS® sysplex or a CICSplex). By using a workload manager (such as z/OS Workload Manager) to adjust resource allocations or work routing in the system in order to meet those performance goals. The z/OS workload manager (WLM) provides transaction activity reporting by service class, report class, or both, based on transaction response time information.

For more information, see The z/OS Workload Manager.

Monitoring data provides information which can be used to assess performance. You can analyze monitoring data reports to choose or adjust performance goals for the system, tackle any performance problems through tuning activities, and make decisions about your future strategy and investments. The CICS monitoring facility collects data about all transactions in the CICS region during online processing for later offline analysis.
