Real storage utilization history attributes

The historical real storage utilization attribute group provides information about the real storage allocated to an address space in terms of various types of frame counts and slot counts, as well as the management status of a given address space.

1 Meg Frames In Real (RMF metric) The number of 1 Megabyte frames backed in real storage.

Active Frames (RMF metric) The number of active frames occupied by the address space.

The average number of frames held by the job while it was active. This value represents the average number of active central storage frames the job used during the report interval.
ACTIVE = SUM Central Srorage Frames / # Samples

Active Frames DIV (RMF metric) The number of active Data-in-Virtual frames actively used by the address space.

The number of central storage frames used by DIV. This count is accumulated only for jobs, not for service classes. A service class displayed on the report may not be the same as where the job was running when the DIV sample was taken.
DIV = SUM DIV Frames / # DIV Samples

Active Frames Fixed (RMF metric) The number of fixed frames actively used by the address space.

The average number of fixed frames the job used during the report interval including frames both above and below the 16 megabyte line. While a user is swapped in, it is the number of fixed frames being used. While a user is swapped out, it is the number of fixed frames that will be used when the user is swapped back in.
FIXED = SUM Fixed Frames / # Samples

Active Frames Working Set (RMF metric) The number of active frames contained in the working set.

The working set value represents the average amount of storage (in frames) a user occupied while in central and expanded storage (not swapped), including dataspaces and hiperspaces. Shared page counts are not included in working set.

ASID The address space ID of the job (hexadecimal format). The address space id of a Job, TSO Userid, started task or UNIX System Services address space.

Auxiliary Storage Slots (RMF metric) The number of auxiliary storage slots occupied by this address space. Valid value is a 4-byte integer.

Idle Frames (RMF metric) The number of idle frames occupied by the address space.

The average number of frames held by the job while it was idle. This value represents the average number of central storage frames the jobs used when it was idle during the report interval.
IDLE = SUM Central Storage Idle Frames / # Samples

Job Name (RMF metric) The name of the Job, the TSO Userid, the name of the started task or the name of an UNIX System Services address space. Valid value is a string, with a maximum of eight characters.

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

Memory Objects Allocated The number of memory objects allocated by this address space. Valid value is a 4-byte integer.

Page-In Rate (RMF metric) Page-In rate (Page-ins per second).

The average number of page-ins per second for an address space.
PAGE IN RATE = SUM Page-in Counts for Group / Resident Time
The calculation is the total number of non-swap page-ins (including VIO page-ins, hiperspace page-ins, shared page group page-ins, and page-ins caused by page faults) during the range period divided by the total time an address space was swapped-in (resident time) in seconds.

Recording End Time Time at the end of the RMF reporting interval for the current row of near-term historical data. The valid format is yy/mm/dd hh:mm:ss.

Recording Start Time Time at the start of the RMF reporting interval for the current row of near-term historical data. The valid format is yy/mm/dd hh:mm:ss.

RMF Status Status indications for availability of RMF and lock data.

Sample Period Sample period in seconds.

Service Class The service class name. Valid value is a string, with a maximum of eight characters. This field displays unavailable if the system is in compatibility mode. If a job changes its service class during the report interval, RMF displays eight asterisks (********) instead of the service class name. If the service class is not available, RMF displays eight dashes (--------).

Shared Page-In Rate (RMF metric) Shared page-in rate from auxiliary storage (Page-ins per second).

Shared storage page-in rate from auxiliary storage. The page-in rate is calculated by dividing the total number of shared pages brought in from auxiliary storage by the resident time. (The resident time is the total time an address space was swapped-in in seconds).

Shared Pages Total Views (RMF metric) The total shared page views. Valid value is a 4-byte integer.

Shared Pages Total Valid (RMF metric) The total valid shared pages. Valid means that the page is brought into central storage and is made addressable for the address space.

Shared Pages Validation Rate (RMF metric) The shared page validation rate of the address space.

Total Frames (RMF metric) The total number of frames occupied by the address space. The sum of the ACTIVE and IDLE frames. The shared page counts are not included in TOTAL.

SMF IDSMF ID as defined in the IEASYM or IEASYS PARMLIB members.
