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]
The sa2 command is a shell script used to invoke the system activity
reporter sar for purposes of generating the standard default daily report
file. The report file generated is, /var/log/sa/sardd where the dd rep-
resents 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.
