KM5 storage summary history attributes

The historical storage summary attribute group displays historical information about virtual memory.

Average High Virtual Shared Backed In Central (RMF metric) The average number of high virtual shared storage pages backed in central storage (in units of 4 KB). Valid value is a 4-byte integer.

Average 1 Meg Pages Backed in Central (RMF metric) The average number of 1 MB pages backed in central storage. Valid value is a 4-byte integer.

Average Memory Objects High Virtual Common (RMF metric) The average number of high virtual common memory objects that are allocated in the system. Average total number of memory objects allocated in the high virtual common storage of the system. This value includes the memory objects that cannot be attributed to an address space. Valid value is a 4-byte integer.

Average Memory Objects High Virtual Shared (RMF metric) The average number of high virtual shared memory objects that are allocated in the system. Valid value is a 4-byte integer.

Average 1 Meg LFAREA Frames Used For 1 Meg Pages (RMF metric) The average number of 1 MB frames in the Large frame area (LFAREA) that were used to satisfy 1 MB pageable page requests. Valid value is a 4-byte integer.

Average 1 Meg Pages Failed Requests (RMF metric) The average number of failed 1 MB pageable pages that were requested. Valid value is a 4-byte integer.

Average 1 Meg Pages Demoted Converted Requests (RMF metric) The average number of demoted 1 MB pageable pages that were converted from 1 MB pages to 4K pages. Valid value is a 4-byte integer.

Percent 1 Meg Frames Used By Memory Objects (RMF metric) The percentage of 1 MB frames used by pageable/disabled reference (DREF) memory objects. Valid value is a 4-byte integer.

Average Pageable 1 Meg Frames Available To Memory Objects (RMF metric) The average number of 1 MB frames that can be used by pageable/disabled reference (DREF) memory objects. This value is calculated by the system at Initial Program Load (IPL) time. Valid value is a 4-byte integer.

High Virtual Shared Percent In Use (RMF metric) The percentage of high virtual shared memory in use by the system. Valid value is a 4-byte integer.

High Virtual Common Average Auxiliary Slots (RMF metric) The average number of high virtual common memory auxiliary storage slots (DASD and SCM). Valid value is a 4-byte integer.

High Virtual Common Average In Use (RMF metric) The average number of high virtual common memory pages that are backed in central storage (in units of 4KB). Valid value is a 4-byte integer.

High Virtual Common Percent In Use (RMF metric) The percentage of high virtual common memory in use by the system. Valid value is a 4-byte integer.

High Virtual Common Average Fixed Frames (RMF metric) The average number of high virtual common memory pages that are fixed in central storage. This value includes the pages that cannot be attributed to an address space or have not been freed during address space termination. Valid value is a 4-byte integer.

High Virtual Shared Average Auxiliary Slots (RMF metric) The average number of high virtual shared memory auxiliary storage slots (DASD and SCM). Valid value is a 4-byte integer.

Managed System A z/OS operating system in your enterprise that is being monitored by an IBM Z OMEGAMON Monitor for z/OS agent. Valid value is a character string with a maximum length of 32 bytes.

Percent 1 Meg Frames Used By Memory Objects (RMF metric) The percentage of 1 MB frames used by memory objects. Valid value is a 4-byte integer.

Percent 1 Meg Frames Used In LFAREA (RMF metric) The percentage of 1 MB frames that are used in the Large frame area (LFAREA). This metric is regardless of whether the frames are actually used for 1 MB pages or used to satisfy 4 KB space requests on a constrained system. Valid value is a 4-byte integer.
