# canonical sar command invocation
sar -f [FILE] [flags] [interval] [count]

# general purpose flags
# -f [FILE] refers to a file in /var/log/sa/saXX where XX is the day of month
# -o [FILE] capture all performance data in a binary file to be read with sar later
#           Note: *all* performance counters are captured by default
# -p flag will pretty print device names rather than using dev{m}-{n} format
# when [interval] is 0 sar will report statistics for time since boot
