KM5 StorageClassMemory Summary attributes

This attribute group monitors an LPAR's usage of Storage Class Memory (SCM).

1 Megabyte Writes Demoted The number of 1 megabyte pages written to Storage Class Memory (SCM) that were demoted to discontiguous 4K blocks. A valid value is an integer. A value of -1 indicates "Unavailable".

Active I/O Threshold This is the count of active Storage Class Memory (SCM) I/O output requests at which paging to local paging datasets (DASD) is considered as an alternative to SCM. For example, if the count of active SCM I/O output requests is greater than this value, then DASD is added to the selection criteria when deciding where to send new SCM I/O output requests. A valid value is an integer. A value of -1 indicates "Unavailable".

Backed 64-Bit Common Pages The number of 64-bit common pages backed by Storage Class Memory (SCM). A valid value is a long long integer. A value of -1 indicates "Unavailable".

Backed 64-Bit Shared Pages The number of 64-bit shared pages backed by Storage Class Memory (SCM). A valid value is a long long integer. A value of -1 indicates "Unavailable".

Backed Shared Groups The number of Shared Page Groups backed by Storage Class Memory (SCM). A valid value is a long long integer. A value of -1 indicates "Unavailable".

Blocks In Error The number of Storage Class Memory (SCM) 4K blocks that are "in error" and cannot be used. A valid value is a long long integer. A value of -1 indicates "Unavailable".

Deferred Non Fault Pages/Sec The count of SCM I/O output requests representing other than page-faults that are deferred to Local Page datasets (DASD). A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Deferred Page Fault Pages/Sec The count of SCM I/O output requests representing page-faults that are deferred to local page datasets (DASD). A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Local Paging Service Time The lowest recent service time for Local Paging Dataset requests, in microseconds, displayed as seconds to 6 decimal places. A valid value is a number to six decimal places accuracy.

LPAR Name The name of the logical partiation (LPAR). If z/OS is running as a guest under VM, this field contains the VM user ID. A valid value is a string of up to 8 characters.

Managed System The z/OS operating system in your enterprise that an OMEGAMON for z/OS agent is monitoring. A valid value is a string of up to 32 characters.

Measurement Interval The time, in seconds to thousandth of a second, over which this observation is calculated. A valid value is a number to three decimal places accuracy.

Percent Used The percentage of Storage Class Memory (SCM) blocks configured to the LPAR currently in use, to hundredths of a percent. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

SCM Local Paging Percent Used The combined Storage Class Memory (SCM) and local page dataset percentage utilized. A valid value is a number to two decimal places accuracy.

SCM Service Time The lowest recent service time for Stroage Class Memory (SCM) requests, in microseconds, displayed as seconds to 6 decimal places. A valid value is a number to six decimal places accuracy.

SMFID The System Management Facility (SMF) identifier for the z/OS system where the OMEGAMON for z/OS monitoring agent collected the data. A valid value is a string of up to 4 characters.

System Name The name of the z/OS image. A valid value is a string of up to 8 characters.

Total 1M Page-Ins/Sec The total number of 1 megabyte page-ins per second. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Total 1M Page-Outs/Sec. The total number of 1 megabyte page-outs per second. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Total 1M Reqs Completed/Sec The total number of 1 megabyte Storage Class Memory (SCM) requests completed per second. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Total 1M Writes Completed/Sec The total number of 1 megabyte Storage Class Memory (SCM) writes completed per second. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Total 4K Reqs Completed/Sec The total number of 4K Storage Class Memory (SCM) requests completed per second. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Total 4K Writes Completed/Sec The total number of 4K Storage Class Memory (SCM) writes completed per second. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".

Total Allocation The total number of 4K SCM Blocks configured to the LPAR. A valid value is a long long integer. A value of -1 indicates "Unavailable".

Total In-Use The total number of 4K Storage Class Memory (SCM) Blocks currently in use by the LPAR. A valid value is a long long integer. A value of -1 indicates "Unavailable".

Total Page-Ins/Sec The total number of 4K page-ins per second. 1 megabyte pages are counted as 256 4K pages. A valid value is a number to two decimal places accuracy. A value of -1 indicates "Unavailable".
