View Process Statistics with an Emphasis on Memory Metrics

The following report example illustrates the process statistics section with a focus on process memory related metrics. Some relevant UAF parameters are also displayed. The example uses the default primary and secondary keys of IMAGENAME and USERNAME. This format of the report is obtained by using the qualifier /PROCESS_STATISTICS=FOCUS=MEMORY_RELATED. To view the report with a different orientation, provide your choice of sort keys. For example, the following syntax presents the statistics by user with a breakdown by image:

/PROCESS_STATISTICS=(FOCUS=MEMORY_RELATED,PRIMARY_KEY=USERNAME,SECONDARY_KEY=IMAGENAME)

The following statements describe the columns in the previous example:

• Primary/Secondary Key-This column lists the primary and secondary key identifiers for the process detail lines. The keys may be Mode, Username, Imagename, Processname, Account, UIC group, Workloadname, or PID.
• SftFlt /Sec-This column provides the average soft pagefault rate per second for the process or processes.
• HrdFlt /Sec-This column provides the average hard pagefault rate per second for the process or processes.
• Ave Private-This column provides the average number of private workingset pages for the process. For more than one process, the value is an average weighted by the processes uptime.
• Ave Global-This column provides the average number of global workingset pages for the process. For more than one process, the value is an average weighted by the processes uptime.
• Ave VA Spac-This column provides the average number of process virtual pages for the process. For more than one process, the value is an average weighted by the processes uptime.
• Obs PFW-This column is set to a Y if the process was observed by the data collector in the pagefault wait scheduler state (PFW).
• Max VA Spac-This column provides the maximum number of virtual address space pages for any one process, for any one recording example.
• Max WSsize-This column provides the maximum working set size (private pages + global pages) of any one process, for any one recording example.
• Ave WSsize-This column provides the average working set size (private pages + global pages) for the process. For more than one process, the value is an average weighted by the processes uptime.
• Ave WSlist-This column provides the average working set list size for the process. For more than one process, the value is an average weighted by the processes uptime.
• WS Default-This column provides the WSDEFAULT value for the process. For more than one process, the value is an average weighted by the processes uptime.
• WS Quota-This column provides the WSQUOTA value for the process. For more than one process, the value is an average weighted by the processes uptime.
• WS Extent-This column provides the WSEXTENT value for the process. For more than one process, the value is an average weighted by the processes uptime.
• Uptime (min)-This column provides the total amount of wall-clock time during which the process(es) were resident on the system, in minutes.
