Each report, regardless of the type or section, contains information
in the header of the report that identifies characteristics of the data. Look
here for descriptions of the header information.
- Report title
- Identifies the type of performance report on the first line. The second
line identifies the section of the report.
- Current date and time
- Indicates the date and time the report was printed.
- Report page number
- Identifies the page of the report.
- Perf data from time to time at interval
- Indicates the time period over which the data was collected and at what
interval.
- User-selected report title
- Indicates the name assigned to the report by a user.
- Member
- Indicates the performance data member used in the report. This name corresponds
to the name used on the MBR parameter of the Create Performance data (CRTPFRDTA)
command.
- Library
- Identifies the library where the performance data used for a particular
report is located.
- Model/Serial
- Indicates the model and serial number of the server on which the performance
data for the report was collected. The serial number can be 10 characters.
- Main storage size
- Indicates the size of the main storage on the server on which the performance
data was collected.
- Started
- Indicates the date and time Collection Services started collecting performance
data for the report. Depending on whether or not you select specific intervals
or a specific starting time, you could see the following:
- Stopped
- The date and time Collection Services stopped collecting performance data
for this report. Depending on whether or not you select specific intervals
or a specific ending time, you could see the following:
- System name
- Indicates the name of the server on which the performance data was collected
for the report.
- Version/Release level
- x/ x.0 indicates which version and release level of the
operating system the server was running at the time the performance data was
collected.
- Partition ID
- 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:
- 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.
- If you collected data with the Start Performance Monitor (STRPFRMON) command
in a previous release, the value for the partition ID is 00.
- 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 Start Service Tools (STRSST) command.
- Feature Code
- Identifies the Interactive feature code value for the server.
- Int Threshold
- 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.
- Virtual Processors
- 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.
- Processor Units
- 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.
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.
- Column headings
- Each report also has several columns that make up the information of the
report. Some are specific to a particular report and others are consistent
between reports. For short descriptions of these columns, see the Performance
Report columns page.
