[ale] Lost sar data?

[Jim Kinney]

Yes and no. It's stored in memory until a process writes it to disk.
Basic sar data is really just reading /proc for numbers. But that is of
course just in memory data. To store it requires a system process that
collects it. That usually runs in cron or as a daemon.

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
