Users concerned about system performance data (and who isn't?) will find Sandra Henry-Stocker's post on Getting started with sar a helpful guide. She shares her experience of using yum install sysstat to install sysstat (the package that contains the sar components) on a Fedora 17 system. (She recommends apt-get install sysstat as an alternative.) With sar installed, Henry-Stocker's Fedora 17 is enabled to collect performance data every ten minutes -- every day of the week -- with daily summaries available shortly before midnight (11:53 PM). But, wait; there's more: Along with sar comes the sadc component, which collects performance data and stores it in a binary data file and the sa1 component, a wrapper for sadc that works in cron jobs, as well as the sa2 script, which gets sar to print a report in ASCII format from the binary information that sadc has stored. Henry-Stocker also writes about how users can get sar (installed by default) up and running on Solaris.
