| + | 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; | ||
| + | - tapestat: reports statistics for tapes connected to the system; | ||
| + | - mpstat: reports global and per-processor statistics; | ||
| + | - pidstat: reports statistics for Linux tasks (processes); | ||
| + | - sadf: displays data collected by sar in various formats; | ||
| + | - cifsiostat: reports I/O statistics for CIFS filesystems. | ||
| + | . | ||
| + | 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. | ||
