-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.
