# Synopsis: Replacement for Sun's sar data collection scripts (/usr/lib/sa/sa1
8
# and /usr/lib/sa/sa2). It uses a month-by-month directory structure to allow
9
# it to keep more than one month's data; datafiles are named YYMMMM/saDD,
10
# and the script maintains links to these datafiles to mimic the standard sar
13
# The script does all of what sa1 does and most of what sa2 does, but it
14
# doesn't bother doing the sar data summarization that sa2 performs since that
15
# data can be generated easily if/when it's needed.
17
# Files are automatically compressed or deleted after specified periods.

# 5/24/2001: Modified to work with Redhat Linux + sysstat 4.0.0
