Real Storage Utilization History attributes

This table 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 that are owned by the address space. A valid value is an integer. A value of -1 indicates "Unavailable".

Active Frames (RMF metric) The average number of frames held by the job while it was active. The average number of active central storage frames the job used during the report interval.

ACTIVE = SUM Central Srorage Frames /
    # Samples
A valid value is an integer. A value of -1 indicates "Unavailable".

Active Frames DIV (RMF metric) The number of Data-in-Virtual (DIV) 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
A valid value is an integer. A value of -1 indicates "Unavailable".

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
A valid value is an integer. A value of -1 indicates "Unavailable".

Active Frames Working Set (RMF metric) The number of active frames actively used by the address space. 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 the working set. A valid value is an integer. A value of -1 indicates "Unavailable".

ASID The address space identifier of the job, in hexadecimal. The address space id of a Job, TSO Userid, started task or UNIX System Services address space. A valid value is an integer, displayed as a hexadecimal string.

Auxiliary Storage Slots (RMF metric) The number of auxiliary storage slots occupied by the address space. A valid value is an integer. A value of -1 indicates "Unavailable".

Fixed 2GB Pages In Central Storage (RMF metric) The average number of 2 GB pages fixed in central storage. A valid value is an integer. A value of -1 indicates "Unavailable".

Freemained Frames (RMF metric) The average number of freemained frames. A valid value is an integer. A value of -1 indicates "Unavailable".

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 
A valid value is an integer. A value of -1 indicates "Unavailable".

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. 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.

Memory Objects 2GB Fixed (RMF metric) The average number of fixed memory objects that are backed in 2 GB frames. A valid value is an integer. A value of -1 indicates "Unavailable".

Memory Objects Allocated (RMF metric) The number of memory objects allocated by the address space. A valid value is an integer. A value of -1 indicates "Unavailable".

Page-In Rate (RMF metric) The average number of page-ins per second for an address space. 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.

PAGE IN RATE = SUM Page-in
    Counts for Group / Resident Time
A valid value is an integer. A value of -1 indicates "Unavailable".

Recording End Time (RMF metric) The time at the end of the RMF reporting interval for the current row of near-term historical data. This time is displayed in the following format:

mm/dd/yy hh:mm:ss (Tivoli Enterprise Portal) or yy/mm/dd hh:mm:ss (3270)

Where:

This time is stored as a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:

Recording Start Time (RMF metric) The time at the start of the RMF reporting interval for the current row of near-term historical data. This time is displayed in the following format:

mm/dd/yy hh:mm:ss (Tivoli Enterprise Portal) or yy/mm/dd hh:mm:ss (3270)

Where:

This time is stored as a string no longer than 16 characters in the format CYYMMDDHHMMSSmmm (as in 1020315064501000 for 03/15/02 06:45:01) where:

RMF Status Status indications for availability of RMF report data. A valid value is an integer. Values appear on the workspace as follows:

Sample Period Sample period in seconds. A valid value is an integer.

Service Class (RMF metric) The service class name. unavailable is displayed when the system is in compatibility mode. If a job changes its service class during the report interval, eight asterisks (********) are displayed instead of the service class name. When the service class is not available, eight dashes (--------) are displayed. A valid value is a string of up to 8 characters.

Shared Page-In Rate (RMF metric) The number of shared storage page-ins per second from auxiliary storage. The shared storage 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. A valid value is an integer. A value of -1 indicates "Unavailable".

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. A valid value is an integer. A value of -1 indicates "Unavailable".

Shared Pages Total Views (RMF metric) The total shared page views for the address space. A valid value is an integer. A value of -1 indicates "Unavailable".

Shared Pages Validation Rate (RMF metric) The shared page validation rate of the address space. A valid value is an integer. A value of -1 indicates "Unavailable".

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.

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 the total. A valid value is an integer. A value of -1 indicates "Unavailable".
