Record Type 74 (4A) — RMF Activity of Several Resources

For information on using RMF™, see z/OS RMF User's Guide.

For information on Monitor I, II, and III, see z/OS RMF Report Analysis.

Record type 74 has the following subtypes:
  • Subtype 1 — Device Activity
    The record is written for all devices specified in the DEVICE option for a Monitor I session. It contains entries for all devices that have been online at least once since RMF was started. The entry for any device that was offline at the end of the reporting interval, or for any device that was taken offline during the interval, does not contain data.
    Device Control data section
    Contains general information on the number of devices and types.
    Device data section
    Contains the volume serial number for tape and direct access devices, number of requests on the device, total active, pending and connect time to service those requests, the number of requests enqueued for the device and the device number, class and type and other data collected about the device. RMF produces one or more type 74 records for the classes requested by the installation, and one Device data section for each device.
  • Subtype 2 — XCF Activity
    Monitor III Cross-System Coupling Facility (XCF) measurement writes this subtype, only if the Monitor III data gatherer is on.
    Control data section
    Contains control information for splitting and reassembling of the XCF records.
    System data section
    Describes the message traffic between the local system (where RMF is running) and the remote systems on a system level.
    Path data section
    Describes the message traffic broken down by signalling paths connecting the local system with the remote systems.
    Member data section
    Describes the message traffic on a member basis for members on the local system and members communicating with the local system.
  • Subtype 3 — OMVS Kernel Activity
    Monitor III Data Gatherer collects z/OS UNIX System Services measurement data that are input for the RMF Postprocessor to create the OMVS Kernel Activity report.
    Control data section
    Contains various z/OS UNIX System Services measurement data.
  • Subtype 4 — Coupling Facility Activity

    One record is written for each coupling facility by each member in the sysplex.

    Local Coupling Facility data section
    One per record; contains path and subchannel data collected from each local system.
    Connectivity data section
    One per sysplex member connected to the coupling facility. This member list is used by the Postprocessor to verify that it has a complete set of SMF records for creating sysplex-level reports for this coupling facility.

    This section is gathered on only one system in the sysplex (RMF's sysplex master gathering) and is available only if the status flag R744FFLG in the Local Coupling Facility data section indicates that the coupling facility was connected to the system at the end of the interval.

    Storage Coupling Facility data section
    One per record; contains global data that is only collected once for the sysplex.
    Structure data section
    One for each structure allocated in this facility.

    This section is gathered on only one system in the sysplex (RMF's sysplex master gathering) and is available only if the status flag R744FFLG in the Local Coupling Facility data section indicates that the coupling facility was connected to the system at the end of the interval.

    Request data section
    One for each structure in this facility if the structure has had an active connection at some time during the interval.
    Processor Utilization data section
    One for each processor (CP, not IOP) within the respective coupling facility.
    Cache data section
    Several sections for each Request data section are possible, depending on applications using the coupling facility.
    Remote Facility data section
    One section for each duplexing coupling facility with various signal counters.
    Channel Path data section
    One section for each channel path of type CIB, CFP, or CS5CIB, CFP, or CS5 associated with a local or remote coupling facility, containing channel path attributes. There can be up to eight Channel Path data sections per coupling facility. Start of changeThere can be up to eight sender and eight receiver Channel Path data sections per remote coupling facility. End of change
    Storage Class Memory data section
    One section for each structure in this coupling facility that is allocated with storage class memory and has had an active connection at some time during the interval.
    Start of changeAsynchronous CF Duplexing data sectionEnd of change
    Start of changeOne section for each asynchronously duplexed structure in the coupling facility.End of change
  • Subtype 5 — Cache Subsystem Device Activity
    One or several records (depending on the number of devices attached to the control unit) are written for each cache subsystem. The header section of each record contains an individual header extension for subtype 5.
    Cache control section
    Contains control information and return codes from interfaces.
    Cache Device data section
    Contains cache statistics for each device.
    Cache Device data extension section
    This extension applies only to control unit types 3990-03 and 3990-06. It is collected by RMF to provide the same data as in the corresponding CRR record.

Note:
  1. All fields with format s_float have the type short format floating point.
  2. All fields with format l_float have the type long format floating point.

Each subtype contains a header section, the individual header extension (which contains offset/length/number triplets to address record parts following the RMF Product section) and the RMF Product section.

Macro to Symbolically Address Record Type 74: The SMF record mapping macro for all records produced by RMF is ERBSMFR. Its format is ERBSMFR (n1,n2,...) where n1,n2, ... are the SMF record types you want to map. Note that the parentheses are required only when two or more record types are specified. The mapping macro resides in SYS1.MACLIB.
