CMF MONITOR similarities with IBM RMF

CMF MONITOR has many similarities with RMF, and some differences. This topic presents the compatibility issues of CMF MONITOR and RMF.

Similarities

  • CMF MONITOR produces SMF type 7x series records that are compatible with the latest release of RMF running on the IBM z/OS level where data is being extracted. You can use CMF MONITOR records with the RMF postprocessor, or you can use the CMF MONITOR Analyzer to process RMF-created records and produce reports.
  • CMF provides APIs (application programming interfaces) to integrate CMF data with other vendor products or user-written applications. CMF APIs allow you to retrieve the same data from CMF MONITOR as is available through RMF APIs.

Differences

CMF MONITOR can start and stop I/O monitoring of devices other than tape and DASD. When this feature is activated, CMF MONITOR makes sure that RMF control of the channel measurement blocks for nontape and non-DASD devices is maintained. RMF assumes that it has exclusive use of all nontape and non-DASD CMBs. CMF MONITOR does not perform start or stop I/O monitoring of this kind if RMF is active and sampling nontape and non-DASD device classes.

Note

CMF MONITOR device monitoring is controlled by the CLASS parameter of the Extractor DEVICE control statement. If SMF type 74 records that are compatible with those produced by RMF are desired, CLASS should be the only parameter used.

CMF MONITOR functions that are unavailable in RMF

CMF MONITOR provides the following Extractor functions that RMF does not have:

  • To reduce overhead, CMF MONITOR allows you to define individual sampling intervals for each sampler that is not event driven.
  • Through its Extractor utilities, CMF allows you to browse SYS1.MAN x data sets online without switching SMF recording to another data set before gaining access to view this data. For more information about Extractor utilities, see Using.
  • CMF MONITOR can run two Extractors from one monitor, one in CPM mode and one in IPM mode. RMF can run only one Extractor.
