Collection of performance monitoring tools for Linux
http://sebastien.godard.pagesperso-orange.fr
The sysstat package contains the sar, sadf, mpstat, iostat, tapestat,
pidstat, cifsiostat and sa tools for Linux.
The sar command collects and reports system activity information.
The information collected by sar can be saved in a file in a binary
format for future inspection. 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.
The sadf command may be used to display data collected by sar in
various formats (CSV, PCP, XML, etc.).
The iostat command reports CPU utilization and I/O statistics for disks.
The tapestat command reports statistics for tapes connected to the system.
The mpstat command reports global and per-processor statistics.
The pidstat command reports statistics for Linux tasks (processes).
The cifsiostat command reports I/O statistics for CIFS file systems.
