Only one report is printed, -after the last file is processed. -.Pp -The labels used in the output indicate the following, except -where otherwise specified by individual options: -.Bl -tag -width k*sec -.It Dv avio -Average number of I/O operations per execution -.It Dv cp -Sum of user and system time, in minutes -.It Dv cpu -Same as -.Dv cp -.It Dv k -CPU-time averaged core usage, in 1k units -.It Dv k*sec -CPU storage integral, in 1k-core seconds -.It Dv re -Real time, in minutes -.It Dv s -System time, in minutes -.It Dv tio -Total number of I/O operations -.It Dv u -User time, in minutes -.El -.Pp -The options to -.Nm sa -are: -.Bl -tag -width Ds -.It Fl a -List all command names, including those containing unprintable -characters and those used only once. By default, -.Nm sa -places all names containing unprintable characters and -those used only once under the name ``***other''. -.It Fl b -If printing command statistics, sort output by the sum of user and system -time divided by number of calls. -.It Fl c -In addition to the number of calls and the user, system and real times -for each command, print their percentage of the total over all commands. -.It Fl d -If printing command statistics, sort by the average number of disk -I/O operations. If printing user statistics, print the average number of -disk I/O operations per user. -.It Fl D -If printing command statistics, sort and print by the total number -of disk I/O operations. -.It Fl f -Force no interactive threshold comparison with the -.Fl v -option. -.It Fl i -Do not read in the summary files. -.It Fl j -Instead of the total minutes per category, give seconds per call. -.It Fl k -If printing command statistics, sort by the cpu-time average memory -usage. If printing user statistics, print the cpu-time average -memory usage. -.It Fl K -If printing command statistics, print and sort by the cpu-storage integral. -.It Fl l -Separate system and user time; normally they are combined. -.It Fl m -Print per-user statistics rather than per-command statistics. -.It Fl n -Sort by number of calls. -.It Fl q -Create no output other than error messages. -.It Fl r -Reverse order of sort. -.It Fl s -Truncate the accounting files when done and merge their data -into the summary files. -.It Fl t -For each command, report the ratio of real time to the sum -of user and system cpu times. -If the cpu time is too small to report, ``*ignore*'' appears in -this field. -.It Fl u -Superseding all other flags, for each entry -in the accounting file, print the user ID, total seconds of cpu usage, -total memory usage, number of I/O operations performed, and -command name. -.It Fl v Ar cutoff -For each command used -.Ar cutoff -times or fewer, print the command name and await a reply -from the terminal. If the reply begins with ``y'', add -the command to the category ``**junk**''. This flag is -used to strip garbage from the report. -.El -.Pp -By default, per-command statistics will be printed. The number of -calls, the total elapsed time in minutes, total cpu and user time -in minutes, average number of I/O operations, and CPU-time -averaged core usage will be printed. If the -.Fl m -option is specified, per-user statistics will be printed, including -the user name, the number of commands invoked, total cpu time used -(in minutes), total number of I/O operations, and CPU storage integral -for each user. If the -.Fl u -option is specified, the uid, user and system time (in seconds), -CPU storage integral, I/O usage, and command name will be printed -for each entry in the accounting data file. -.Pp -If the -.Fl u -flag is specified, all flags other than -.Fl q -are ignored. If the -.Fl m -flag is specified, only the -.Fl b , -.Fl d , -.Fl i , -.Fl k , -.Fl q , -and -.Fl s -flags are honored. -.Pp -The -.Nm sa -utility exits 0 on success, and >0 if an error occurs. -.Sh FILES -.Bl -tag -width /var/account/usracct -compact -.It Pa /var/account/acct -raw accounting data file -.It Pa /var/account/savacct -per-command accounting summary database -.It Pa /var/account/usracct -per-user accounting summary database -.El -.Sh SEE ALSO -.Xr ac 8 , -.Xr acct 5 , -.Xr accton 8 , -.Xr lastcomm 1 -.Sh BUGS -The number of options to this program is absurd, especially considering -that there's not much logic behind their lettering. -.Pp -The field labels should be more consistent. -.Pp -NetBSD's VM system does not record the CPU storage integral. -.Sh CAVEATS -While the behavior of the options in this version of -.Nm sa -was modeled after the original version, there are some intentional -differences and undoubtedly some unintentional ones as well. In -particular, the -.Fl q -option has been added, and the -.Fl m -option now understands more options than it used to. -.Pp -The formats of the summary files created by this version of -.Nm sa -are very different than the those used by the original version. -This is not considered a problem, however, because the accounting record -format has changed as well (since user ids are now 32 bits). -.Sh HISTORY -.Nm Sa -was written for -.Nx 0.9a -from the specification provided by various systems' manual pages. -Its date of origin is unknown to the author. -.Sh AUTHOR -.Bl -tag -Chris G.
