Best Way to measure ZIIP Processor Usage - RMF or other?

  • 1.  Best Way to measure ZIIP Processor Usage - RMF or other?

    Posted Tue June 27, 2023 09:10 AM

    Hi,

    We're running ZOS 2.5 and have ZIIP processors and wanted to run some reports to determine overall ZIIP usage and by what jobs, started tasks, programs are using?  What is best way to report and measure on such usage of the ZIIP processors?

    Please advise.

    Thanks,

    Steve Estle

    Steve:

     

    RMF (or CMF) have lots of reports on zIIP usage. But if you are interested at the job level, I would suggest you download zBNA (and CP3KEXTR). CP3KEXTR will reduce your SMF data into a format which can be used by zPCR and zBNA. zBNA lets you look at job and dataset level info, including zIIP utilization by job or program.

     

    CP3KEXTR is at https://www.ibm.com/support/pages/zos-data-extraction-program-cp3kextr-zpcr-and-zbna

    zBNA is at https://www.ibm.com/support/pages/ibm-z-batch-network-analyzer-zbna-tool-0

    Agree on SMF 30 and zBNA, Jim. I'm not sure, though, it would handle SMF 30 Interval records (Subtypes 2 and 3). These would be important for eg long running tasks such as Db2 and CICS (Liberty Profile).

    Martin:


    According to the doc zBNA uses SMF Type 30 subtypes 2, 3, 4 and 5.

    All of the major (and minor) performance monitoring tools (Omegamon, Sysview, Mainview, TMON, et al) will give you many different slices at zIIP measurements (e.g. total use, use by address space/STC/job, use by enclave, zIIP eligible but not run on zIIP), it's just a matter of looking for the pages/panels that display what you want.

    Agree Scott. I'm glad you raised zIIP-on-GCP. This is visible in RMF (72-3) and SMF 30 (all subtypes). What ISN'T in these records is why. SMF 70 Subtype 1 gives much of the answer, though some WLM-related clues might appear in 72-3.

    "What ISN'T in these records..."

    Which is why I'd recommend that the customer use the tools they bought instead of inventing new ones... the likelihood of combining the records right the first (seventeenth?) time is ... unlikely.
