Sources of CICS data


The primary sources of CICS performance data are the IBM CICS Monitor Program (CMP), the BMC AMI Ops Monitor for CICS product, and ASG Technologies' ASG-TMON for CICS TS for z/OS (TMON for CICS).

CMP, BMC AMI Ops Monitor for CICS, or TMON for CICS gather data that reflect the use of system resources during user-specified operating intervals and write the information to an output data set.

From CMP, BMC AMI Ops Monitor for CICS, or TMON for CICS data, UIE derives the following information:

  • Transaction count
  • Application CPU usage per transaction
  • Average response time
  • Total I/O count per transaction

By default, UIE processes the IBM 110 data for each CICS region for which 110 data is found. However, before processing any CICS data, UIE checks for the presence of BMC AMI Ops Monitor for CICS and TMON for CICS data sets. If either BMC AMI Ops Monitor for CICS or TMON for CICS data is found, the following actions occur:

  • If only BMC AMI Ops Monitor for CICS data is found, processing of 110 data is turned off for all systems and the BMC AMI Ops Monitor for CICS data is considered the only CICS data source.
  • If only TMON for CICS data is found, processing of 110 data is turned off for all systems and the TMON for CICS data is considered the only CICS data source.
  • If both BMC AMI Ops Monitor for CICS and TMON for CICS data are found, processing of 110 data and TMON for CICS data are turned off for all systems and BMC AMI Ops Monitor for CICS is considered the only CICS data source.

If you want to process a mixture of CICS data sources, you can use the APPLControl command to indicate which data source should be processed for a specific system or CICS region. For more information about the APPLControl command, see APPLCONTROL.

Important

  • If you have multiple CICS regions executing in the same service class, and you only input CICS monitor data for some of those CICS regions, you need to create a separate suite for each CICS region for which you have provided CICS monitor data. For more information, see the last note about the SUITE DETAIL parameter in SUITE.
  • In addition to transaction performance data, UIE also processes the statistics data that is created by CICS. CICS statistics data contains information about performance and resource usage throughout the CICS system.
