Monitoring IMS and participating z/OS components

With IBM® z/OS® Workload Interaction Correlator, IMS data is collected as part of unified workload insights across the entire z/OS middleware stack. The unified insights enable system administrators to reduce downtime without additional subject matter experts or specialized mainframe skills, which makes monitoring IMS less challenging and costly.

The collection of activities data can be summarized based on core type, job size, and job priory. This helps diagnose performance issues when underlying IMS problems are correlated with other z/OS components .

IMS registers with IBM z/OS Workload Interaction Correlator during initialization and delivers statistical data to it through a z/OS System Management Facility (SMF) exit. For every normally complete transaction, Message Processing Program (MPP) regions and Java message processing (JMP) regions record both elapsed time and CPU time in a standard form and in an IBM System z Integrated Information Processor (zIIP) form.

IBM z/OS Workload Interaction Correlator provides high-frequency IMS dependent region statistics. At each interval, activity statistics, and exceptional jobs and activities are recorded which you can use to further analyze performance and identify anomalies.
