Description: 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 disk I/O statistics;
– 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 deal with 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.
