SMF 110 data

System Management Facilities (SMF) record type 110 data is generated by CICS® Transaction Server for z/OS® for monitoring region-wide transaction statistics, transaction-level statistics, and storage exceptions. This data highlights potential problems in CICS system operation and can help you identify system constraints that affect the performance of your transactions.

SMF 110 data generation

When it sends data to IBM Z Operations Analytics, the IBM Z Common Data Provider System Data Engine collects only a subset of the SMF record type 110 data that is generated by CICS Transaction Server for z/OS. For example, the following data is some of the data that is collected from SMF record type 110:
  • Monitoring exceptions data for CICS Transaction Server for z/OS from SMF type 110 subtype 1 records, with a class where data = 4.

    The SMF110_E record type contains this data.

  • Global transaction manager statistics data for CICS Transaction Server for z/OS from SMF type 110 subtype 2 records, with a class where STID = 10

    The SMF110_S_10 record type contains this data.

To enable the generation of SMF record type 110 data, you must include the SMF 110 record type in the single SMF log stream that the System Data Engine processes. You must also define the following CICS Transaction Server for z/OS initialization parameters in the SYSIN data set of the CICS startup job stream:

STATRCD=ON,              Interval statistics recording
STATINT=001000,          Interval definition
MN=ON,                   Turn monitoring on or off
MNEXC=ON,                Exceptions monitoring
MNRES=ON,                Resource monitoring

For more information about enabling the generation of SMF record type 110 data, see Specifying system initialization parameters before startup in the CICS Transaction Server for z/OS Version 5.3 documentation.

Important:

For the IBM Z Operations Analytics machine learning system, SMF type 110 subtype 2 records must be generated in 10-minute intervals.
