RMF zSeries Common Information Model (CIM) monitoring

z/OS CIM implements the CIM server that is based on the OpenPegasus open source project. A CIM monitoring client invokes the CIM server that, in turn, collects z/OS metrics from the system and returns them to the calling client.

To get the z/OS metrics, the CIM server invokes the z/OS RMF monitoring provider that retrieves the metrics associated with z/OS system resources.

The z/OS RMF monitoring provider uses existing and extended RMF Monitor III performance data. The metrics that are obtained by this new API are common across  platforms, so you can use it to create end-to-end monitoring applications.

Monitoring zFS UNIX file system activity
Two new Monitor III reports provide overview and performance information about zFS activity:

• The zFS Summary Report helps to control the zFS environment and I/O balancing.
• The zFS Activity Report measures zFS activity on the basis of single file systems, for example, a file system’s performance and DASD utilization.

Monitoring storage group and disk space
Two new Monitor III reports support disk space monitoring at the storage group level as well as at the volume level:

• The Storage Space Report displays information about capacity and available space for defined storage groups.
• The Disk Space Report provides capacity and space information for volumes that belong to the defined storage groups.

Support for IBM System z9 processors
On z900 and z990 processors, special purpose processors IFLs (Integrated Facility for Linux®) and IFAs (Integrated Facility for Applications) are reported as ICFs (Internal Coupling Facility). Starting with IBM System z9 (z9109) processors, IFLs, IFAs and ICFs are reported separately in the
Postprocessor Partition Data Report and the Monitor III CPC Report.

Support of Crypto Express2 hardware
RMF has enhanced the Crypto Hardware Activity Report to support the new Crypto Express2 Coprocessor crypto card.

Preferred Paths Support
For control units supporting path attributes for connected channel paths, RMF has enhanced the I/O Queuing Activity Report, so that it now shows these attributes, if applicable, for CHPIDS that are connected to these eligible control units.

Monitor III Data Reporter Tables
Two new tables have been introduced to support monitoring of zFS UNIX® file system activity:

• Table ERBZFST3 is available for the new Monitor III zFS Summary Report that helps to control the zFS environment and delivers information about which tuning possibilities of zFS could be applied.
• Table ERBZFAT3 is available for the new Monitor III zFS Activity Report that measures zFS activity on the basis of single file systems, for example, a file system’s performance and DASD utilization.

Two new tables have been introduced to support disk space monitoring:

• Table ERBSPDT3 is available for the new Monitor III Disk Space Report that provides information about capacity and available space for defined storage groups.
• Table ERBSPGT3 is available for the new Monitor III Storage Space Report that provides capacity and space information for volumes that belong to the defined storage groups.

Queue length distribution in the CPU Activity Report
The presentation of the queue length distribution in the System Address Space Analysis section of the CPU Activity Postprocessor report has been changed to reflect the higher number of CPUs available per MVS image.
