Unexpected Increase in CPU
The Unexpected Increase in CPU report set is useful when a CICSĀ® systems programmer sees a notification that some of the transactions on one or more CICS systems are experiencing increases in CPU time.
The increase in CPU time information was provided by the delivery manager from service level agreement (SLA) reports. The systems programmer wants to know which reports to run to determine the causes of the increase in CPU. Based on these reports and analysis, the systems programmer can then consider tuning options as well as further analysis and monitoring.
The report set produces the following reports:
- Monitoring Global Statistics
- Transaction Summary
To produce the reports, the following components are used:
Component name | Component type | Description |
