Command report
The Command report displays the memory usage statistics for the specified command names. To print the command report, specify the -C flag.
- Command
- Indicates the command name.
If processes running this command use pages of size other than the base 4KB page size, and the -O pgsz=on option is set, these statistics are followed by breakdown statistics for each page size. The metrics reported in this per-page size summary are reported in the page size unit by default.
Examples:
- To display memory statistics about the yes command, with breakdown
by process and categorized detailed statistics by segment, enter:

The report is divided in several sub-reports. The summary line for the command displays the Inuse memory, the Pin pages in memory, the paging space and virtual pages used by the command. The -O process=on option adds the process section, where we have the list of the processes for this command.
- To display memory statistics about the yes command, with
breakdown by process and statistics by segment including file names,
enter:
# svmon -C yes -O summary=basic,segment=on,pidlist=on,filename=onUnit: page =============================================================================== Command Inuse Pin Pgsp Virtual yes 14405 5492 0 14404 Vsid Esid Type Description PSize Inuse Pin Pgsp Virtual 502d d work shared library text m 502 0 0 502 Shared library text segment 2002 0 work kernel segment m 396 343 0 396 System segment 13722 2 work process private sm 19 4 0 19 pid(s)=397566 1a72b f work shared library data sm 17 0 0 17 pid(s)=397566 1b70a 1 clnt code,/dev/hd2:338 s 1 0 - - /usr/bin/yes pid(s)=397566, 295038, 217212This report displays for each segment its list of pids when the segment is in a process address space. It also displays the filename of all client and persistent segments.
- To display memory statistics about the init command, with
breakdown by process, enter:
# svmon -@ -C init -O commandline=on,segment=off,process=on# svmon -@ -C init -O commandline=on,segment=off,process=on Command line : svmon -@ -C init -O commandline=on,segment=off,process=on Unit: page =============================================================================== Command Inuse Pin Pgsp Virtual init 18484 8900 0 18469 ------------------------------------------------------------------------------- Pid Command Inuse Pin Pgsp Virtual 1 init 18494 8900 0 18477 WPAR=Global 159976 init 18484 8900 0 18469 WPAR=wp1 233722 init 18484 8900 0 18469 WPAR=wp2 180562 init 18484 8900 0 18469 WPAR=wp0 -------------------------------------------------------------------------------In a WPAR context, the -@ flag combined with the -O process=on flag, adds WPAR information in the report. This example shows which init process belongs to which WPAR.
