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 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 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 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 SCM. A valid value is a long long integer. A value of -1 indicates "Unavailable".
Blocks In Error The number of 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). A valid value is a string of up to 8 characters.
Managed System 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 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 SCM and Local Page Dataset percentage utilized, to 2 decimal places. A valid value is a number to two decimal places accuracy.
SCM Service Time The lowest recent service time for SCM (Storage Class Memory) 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 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 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 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 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 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 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".
