KM5 Top Consumers attribute group

The KM5 Top Consumers attribute group provides information on top consumers of various resources, including CPU, storage, I/O, enqueue conflicts, and Performance Index, for all LPARs in the central processing complex (CPC) or Sysplex.

% of Total CSA Percentage of total common service area (CSA) storage in use by this job. Valid value is a number in the range 0 - 100.

ASID The address space ID in hexadecimal. The address space ID is a unique number assigned to an address space when it is created. It is used by z/OS as an index to find the main control bock of the address space or to differentiate between address spaces.

Central Frame Count The total number of central storage frames, including any frames that are backing user data spaces. Valid value is a 4-byte integer.

CPC Model Number The model number of the central processing complex (CPC) where the LPAR is running.

CPC Serial Number The 6-character central processing complex (CPC) serial number.

CPU Percent The percentage of CPU utilized by the address space over the current interval. The value can exceed 100%. The maximum value is n 00%, where n represents the number of processors (CPUs) assigned to the LPAR or image.

CSA in Use Amount of common service area (CSA) storage in use by this address space, in bytes. Valid value is a numeric value in the range 1 - 2147483647.

CSA Orphaned Indicates whether or not the storage is currently owned. Valid values are:

Not available

Address space did not allocate CSA storage

Yes

CSA storage was orphaned by this address space and is currently unowned

No

Address space is active and this CSA storage is owned

I/O Rate The average number of reads and writes (I/Os) per second during the last sample interval, to one decimal place. (By default, the sample interval is 2.3 seconds.)

Job Name The name of the job, started task, TSO user, APPC address space, and so on, consuming CPU cycles. Valid value is a string, with a maximum of eight characters.

LPAR Name Name of the LPAR For this row of data.

Major Name The major name (qname) of the resource. Valid format is a simple text string of from 1 through 8 characters; for example, SYSDSN.

Managed System A z/OS operating system in your enterprise that is being monitored by an OMEGAMON XE on z/OS agent. The name takes the form: <SYSPLEX>:<SYSPLEX>:PLEXVIEW.

Max Enqueue Wait Time Longest time, in seconds, that the task has been waiting for a resource. Valid value is an integer in the range of 0 through 2147483647, and can include the use of the *AVG, *MAX, *MIN, or *SUM functions. An example is 45.

Owning Job Name Name of the job containing the task that owns the resource. Valid format is a simple text string from 1 through 8 characters; for example, PRODJOB1. The column is blank for a waiting address space entry.

Performance Index Performance index for the host; a measure of how well a service class period is performing relative to its goal. Valid value is a 4-byte integer in the range 0.00 - 100.00. A performance index of less than 1 indicates that the period is performing better than its goal. A performance index of 1 indicates the period is meeting its goal. A performance index greater than 1 indicates the period is performing worse than its goal.

Average and percentile response time performance indexes are calculated by dividing the actual values by the goal values. The velocity performance index is calculated by dividing the goal value by the actual value.

Service Class The name of the service class being reported on. Valid value is a simple text string of from 1 through 8 characters; for example, TSO. A service class represents a uniquely-named group of work having common performance requirements such as similar performance goals, availability requirements, resource requirements, or business importance.

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

Sysplex Name The name of the Sysplex into which this system has been defined.

Sysplex Node The thrunode of the parent system that collects data from the agent. This is the name ofTivoli Enterprise Monitoring Server specified during configuration of the agent.

Sysplex Originnode The origin node of the parent system that collects data from the agent. The name takes the form: <PLEXNAME>:<SMFID>:MVSSYS.

System Name Name of the z/OS image.

Top Consumer Key Key field identifying the top consumer category of the top or highest consumers of interest. The possible values are: CPU, STORAGE, IO, ENQUEUE, or WLM. For example: SELECT CPUPCT FROM KM5TOPC WHERE TOPCKEY = 'CPU';

Total Fixed The total amount of fixed storage, in megabytes, for the address space. Valid value is a 4-byte integer.

Total Virtual The total amount of allocated virtual storage, in megabytes, for the address space. Valid value is a 4-byte integer.

VM User ID The z/VM user ID in which the guest MVS system is running.

Working Set Size The number of frames of real storage an address space has in use. Often defined as the minimum number of pages that an application needs to do work. With expanded storage installed, working set size also includes the number of expanded storage frames that the user owns. In systems with expanded storage, the working set is divided into three parts. The primary working set consists of LSQA pages, fixed pages, and at least one page per segment. The secondary working set is all other referenced pages. The remaining, unreferenced pages are contained in the nonworking set.
