Performance class data is detailed transaction-level information, such as the processor and elapsed time for a transaction, or the time spent waiting for I/O. At least one performance record is written for each transaction that is being monitored. Performance class data provides detailed, resource-level data that can be used for accounting, performance analysis, and capacity planning. This data contains information relating to individual task resource usage, and is completed for each task when the task terminates.
The Monitoring Control Table (MCT) controls the CMF performance data that is collected. The performance class data records are not fixed format, instead the format is described in associated CMF dictionary records.
All the CMF performance class data fields are described in this section. Each data field is listed by Field ID within Owner as defined in the monitoring dictionary record.
For a complete description of the fields and to understand how the fields are collected, see the CICS® Performance Guide.
