<dd>Identifies the ID of the partition on which the collection was run. This

change accommodates the logical partition implementation. Here are some of
|
||
|
|
the values that you might see: <ul><li>If your system is not partitioned (which is the default) or you used Collection
|
||
|
|
Services to collect and print the performance data for the primary partition
|
||
|
|
of a logical partition system, this value is 00.</li>
|

|
|
<li>If you collected data with the <span class="cmdname">Start Performance Monitor (STRPFRMON)</span> command
|
||
|
|
in a previous release, the value for the partition ID is 00.</li>
|
||
|
|
<li>If you used Collection Services to collect and print the performance data
|
||
|
|
in any secondary partition of a logical partition system, this value is the
|
||
|
|
same as the partition ID that is shown on the Work with System Partitions
|
||
|
|
display under the <span class="cmdname">Start Service Tools (STRSST)</span> command.</li>

<dt class="dlterm">Feature Code</dt>

|

<dt class="dlterm"> <span class="uicontrol">Int Threshold</span> </dt>
|
||
|
|
<dd>Indicates the percent of the total system CPU for interactive work that
|
||
|
|
was used during the collection period. The value is obtained from the QAPMCONF
|
||
|
|
file (GKEY IT) and reflects the configuration metric obtained when the collection
|
||
|
|
started. You should be aware that this value may change for each interval
|
||
|
|
within a collection period due to dynamic changes in logical partition configuration.</dd>
|
||
|
|
<dt class="dlterm">Virtual Processors</dt>
|
||
|
|
<dd>The number of virtual processors configured for the partition. The value
|
||
|
|
is obtained from the QAPMCONF file (GKEY 13)and reflects the configuration
|
||
|
|
metric obtained when the collection started. You should be aware that this
|
||
|
|
value may change for each interval within a collection period due to dynamic
|
||
|
|
changes in logical partition configuration.</dd>
|
||
|
|
<dt class="dlterm">Processor Units</dt>
|
||
|
|
<dd>The number of processor units allocated to the partition. The value is
|
||
|
|
obtained from the QAPMCONF file (GKEY PU) and reflects the configuration metric
|
||
|
|
obtained when the collection started. You should be aware that this value
|
||
|
|
may change for each interval within a collection period due to dynamic changes
|
||
|
|
in logical partition configuration. <p>Processing units are a unit of measure
|
||
|
|
for shared processing power across one or more virtual processors. One shared
|
||
|
|
processing unit on one virtual processor accomplishes approximately the same
|
||
|
|
work as one dedicated processor. One shared processing unit on two virtual
|
||
|
|
processors accomplishes approximately half the work of two dedicated processors.</p>

<dd>Each report also has several columns that make up the information of the

between reports. For short descriptions of these columns, see the Performance
