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.
