Both "sar" and "iostat" are part of the sysstat package.

Description: sar, iostat and mpstat - system performance tools for Linux
The sysstat package contains the following system performance tools:
* sar - collects and reports system activity information;
* iostat - reports CPU utilization and I/O statistics for disks;
* mpstat - reports global and per-processor statistics;
* pidstat - reports statistics for Linux tasks (processes);
* sadf - displays data collected by sar in various formats.
.
The statistics reported by sar concern I/O transfer rates,
paging activity, process-related activities, interrupts,
network activity, memory and swap space utilization, CPU
utilization, kernel activities and TTY statistics, among
others. Both UP and SMP machines are fully supported.
