sautility reports on, cleans up, and generally maintains system accounting files. See accton(8) for details on enabling system accounting.
sa is able to condense the information in
/var/account/acct into the summary files
/var/account/usracct, which contain system
statistics according to command name and login ID, respectively. This
condensation is desirable because on a large system,
/var/account/acct can grow by hundreds of blocks per
day. The summary files are normally read before the accounting file, so that
reports include all available information.
If file names are supplied, they are read instead of /var/account/acct. After each file is read, if the summary files are being updated, an updated summary will be saved to disk. Only one report is printed, after the last file is processed.
The labels used in the output indicate the following, except where otherwise specified by individual options:
The options are as follows:
saplaces all names containing unprintable characters and those used only once under the name “***other”.
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
-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
-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.
-u flag is specified, all flags
-q are ignored. If the
-m flag is specified, only the
-s flags are
sautility exits 0 on success, and >0 if an error occurs.
sawas written for NetBSD 0.9A from the specification provided by various systems' manual pages. Its date of origin is unknown to the author.
sawas modeled after the original version, there are some intentional differences and undoubtedly some unintentional ones as well. In particular, the
-qoption has been added, and the
-moption now understands more options than it used to.
The formats of the summary files created by this version of
sa are very different than 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
The field labels should be more consistent.
OpenBSD's VM system does not record the CPU storage integral.
