In z/OS V2.1, these RMF enhancements are planned:

• RMF will be designed to offload a portion of its processing to zIIP processors, when zIIP processors are installed and configured in the LPAR.
• A new interrupt delay time measurement is available on IBM zEnterprise EC12 (zEC12) servers. With z/OS V2.1, or z/OS V1.12 or V1.13 and the PTF for APAR OA39993, RMF is designed to report on interrupt delay time to help you determine whether I/O processing delays are occurring. This new measurement is designed to measure the time between when primary status is presented to the channel subsystem and when the operating system clears the primary status to begin processing the interrupt. RMF is also designed to write this information to new fields in SMF type 74 subtype 1 and SMF 79 subtype 9 records, and to display averaged interrupt delay times in the Postprocessor Device Activity report.
• RMF will be designed to provide additional information about Global Mirror collisions in RMF Monitor I and in SMF 74 subtype 5 records. A Global Mirror collision happens when a consistency group is in the process of being mirrored and an update to one of the volumes occurs. The update must sometimes wait for the original data to be mirrored, which can cause I/O write delays. This support is also available on z/OS V1.12 and z/OS V1.13 with the PTF for APAR OA40376.
• New RMF function is planned to allow the Monitor I Postprocessor Coupling Facility Activity report and the Monitor III CFSYS report to be used to provide additional information about the coupling facility and CF links. This design extends both to indicate channel path details for each of the Coupling over InfiniBand (CIB) link types, including:
  • Indication whether the CHPID is running in a "degraded" status
  • Channel path type
  • HCA adapter and port number
  • Calculated length of each of the links
    This information is intended to help with monitoring and tuning of the Parallel Sysplex . This support is also available on z/OS V1.12 and z/OS V1.13 with the PTF for APAR OA37826.
• With z/OS V1.13 and z/OSMF V1.13, RMF provided CIM-based performance data gatherers for Linux on System z , Linux on System x , and AIX systems to provide a consistent monitoring solution for zEnterprise ensembles. Along with the Resource Monitoring plug-in for the z/OS Management Facility, first made available with z/OSMF V1.12, this function is intended to display performance metrics from those platforms and combine them with z/OS metrics in common graphic views. In z/OS V2.1, this capability is planned to be extended by providing new SMF 104 Records to provide performance-related information about Linux on System z , and also about Linux on System x , AIX , and Windows Server 2008 operating systems running on zBX blades. This is intended to help provide the basis of performance and capacity planning management for these operating systems on zBX blades in addition to the support already provided by z/OS related SMF records. Windows Server support is planned to require the Standards Based Linux Instrumentation for Manageability CIM client API, which is part of the IBM Systems Director Platform Agent for Windows . This function is planned to be available to be downloaded from
