Sar (Unix)

Sar was originally developed for the Unix System V operating system; it is available in AIX, HP-UX, Solaris and other System V based operating systems but it is not available for macOS or FreeBSD. Prior to 2013 there was a bsdsar tool, but it is now deprecated. Most Linux distributions provide sar utility through the sysstat package. == Syntax ==

The default is the current daily data file /var/adm/sa/sadd. ; : time Selects data up to time. The default is 18:00. ; : sec Selects data at intervals as close as possible to sec seconds. == Example ==
