5.1 Flags

The availability of these program options depends on your operating system. In specific, the members that appear in the struct acct of your system's process accounting header file (usually acct.h) determine which flags will be present. For example, if your system's struct acct doesn't have the ac_mem field, the installed version of sa will not support the --sort-cpu-avmem, --sort-ksec, -k, or -K options.

In short, all of these flags may not be available on your machine.


Force sa not to sort those command names with unprintable characters and those used only once into the `***other' group.


Sort the output by the sum of user and system time divided by the number of calls.


Print percentages of total time for the command's user, system, and real time values.


Sort the output by the average number of disk I/O operations.


Print and sort the output by the total number of disk I/O operations.


When using the --threshold option, assume that all answers to interactive queries will be affirmative.


Don't read the information in savacct.


Instead of printing total minutes for each category, print seconds per call.


Sort the output by cpu time average memory usage.


Print and sort the output by the cpu-storage integral.


Print separate columns for system and user time; usually the two are added together and listed as cpu.


Print the number of processes and number of CPU minutes on a per-user basis.


Sort the output by the number of calls. This is the default sorting method.


Print the number of minor and major pagefaults and swaps.


Print the number of minor and major pagefaults and swaps divided by the number of calls.


Sort output items in reverse order.


Merge the summarized accounting data into the summary files savacct and usracct.


For each entry, print the ratio of real time to the sum of system and user times. If the sum of system and user times is too small to report--the sum is zero--*ignore* will appear in this field.


For each command in the accounting file, print the userid and command name. After printing all entries, quit. Note: this flag supersedes all others.

-v num
--threshold num

Print commands which were executed num times or fewer and await a reply from the terminal. If the response begins with y, add the command to the **junk** group.


It really doesn't make any sense to me that the stock version of sa separates statistics for a particular executable depending on whether or not that command forked. Therefore, GNU sa lumps this information together unless this option is specified.


Sort the output by the "real time" (elapsed time) for each command.

--ahz hz

Use this flag to tell the program what AHZ should be (in hertz). This option is useful if you are trying to view an acct file created on another machine which has the same byte order and file format as your current machine, but has a different value for AHZ.


Print verbose internal information.


Print sa's version number.


Print sa's usage string and default locations of system files to standard output.

Note: if more than one sorting option is specified, the list will be sorted by the one specified last on the command line.
