sar: System statistics

Sar is a utility that will grab cpu, disk i/o, memory, and network statistics on a 10 minute interval. Sar is great for grabbing system statistics quickly; I use sar whenever I'm doing any kind of performance tuning or troubleshooting. To use sar all you need to do is install the sysstat package. The package will install a cron in /etc/cron.d that will kick off a sar capture every 10 minutes....
