iostat is only real time view while you are running it.
sysstat collects long term data and keeps for weeks(cpu, disk,
network, and a lot of other things). I generally turn systat/sar down
to 1 minute so I have more detailed data. It is useful when
something odd happens to see what the system looked like.
