sa2(8) BSD System Manager's Manual sa2(8)
sa2 -- Generate a system activity daily report file.
/usr/lib/sa/sa2 [-dgpu] [-n mode] [-e time] [-f filename] [-i seconds] [-s time]
The sa2 command is a shell script used to invoke the system activity reporter sar for pur-
poses of generating the standard default daily report file. The report file generated is,
/var/log/sa/sardd where the dd represents the current day of the month. The sa2 options are
the same as those documented in sar(1).
When sa2 runs, it will also remove data and report files, found in /var/log/sa, that are
more than one week old.
The sa2 command is intended to be started by cron.
