Installation guide

If you invoke the sa command with no options, the default output consists
of six unheaded columns. Certain command options allow you to expand
the six columns to include more information. You can specify options to
change the format and to output additional information that includes an
identifying suffix. Refer to the sa
(8) reference page for information on the
command options.
The following example shows the default format of the output of the sa
command:
# /usr/sbin/sa

1 Shows information about the number of command executions. An
additional column is added to show the command percentage if you
specify the −c option.
2 Shows information about the amount of real time used. An additional
column is added to show the real-time percentage if you specify the −c
option.
3 Shows information about CPU time used. Depending on the options
specified, the column can show the total system and user CPU time,
the user CPU time, the system CPU time, or the ratio of user CPU
time to system CPU time. An additional column is added to show the
real-time percentage if you specify the −c option. Also, an additional
column is added to show the ratio of real time to total user and system
CPU time if you specify the −t option.
4 Shows information about disk I/O operations, either the average
number of I/O operations or the total number of I/O operations.
5 Shows information about kiloblocks (number of blocks multiplied by
1024) used or the memory time integral.
6 Shows the command name.
The following example adds three columns to the default format to display
the following percentages:
# /usr/sbin/sa -c
