  • 1.  Real memory consumption variable

    Posted Nov 19, 2020 10:15 AM
    I miss a variable for tracking physical memory consumption allocated in an LPAR.

    Using the RMSTG command, I found the measurements "RealStg" and "FreRStg". If I don't get it wrong, with the information from these two columns (subtracting "FreRStg" from "RealStg") I get the actual allocated memory consumption for that specific LPAR.

    Is there another command that brings me this information without having to perform this calculation?

    Still, there is the suggestion to include a column that displays the actual memory consumption information allocated from that LPAR.

    With that same intention, I tried to find some variable that gives me this information, but the closest I found were the variables "STGREAL", "STGREALT" and "STGREALU", but I didn't find a variable that brings me the information in the column "FreRStg "from the RMSTG command.

    If this variable does not exist, here is the suggestion for developing it and another one that brings the consumption information of REAL MEMORY ALLOCATED in percentage and in Megabytes.

    Hi Felix,

    Please check the STORAGE display in CA Sysview.. 
    The STORAGE command displays a summary of system storage statistics that have been collected by the MVS data collector.
    At this screen all kind of storage of your MVS system is displayed...

    Further, if you enter MVSVAR you see all MVS variables and one of the is Group SYSTEM Subgroup STORAGE.. 
    Here are all kind of variable you can use for the thresholds..
    See if one of these gives you the required information.

    Best regards,
    Hennie Hermans

    Good morning Henny,

    The STORAGE command, brings less information than the RMSTG command and also does not bring the information I specified.

    I had already checked the variables in the VARs command and found no variables that showed me the actual memory consumption allocated to a partition.

    Variable STGAFQA 'Available frame queue average' would be similar to FreRStg on RMSTG.  This is the number of available frames, so multiply by 4096 for bytes.

    To request RMSTG be enhanced to show a field like UsdRStg and/or additional metrics to show this value, please submit your request in the Ideation section of Communities.

    Thanks for the guidance Douglas. I submitted my request for analysis. https://community.broadcom.com/participate/ideation-home/viewidea?IdeationKey=9ebb13f1-ee75-4a45-b553-56f0dff38417
