sysstat

sysstat

The sysstat utilities are a collection of open source performance monitoring tools for Linux. The utilities include mpstat, iostat, nfsiostat-sysstat, cifsiostat, pidstat, sar, sadc, sadf and sa tools.

  • iostat - reports CPU statistics and input/output statistics for devices, partitions and network filesystems
  • mpstat - reports individual or combined processor related statistics
  • pidstat - reports statistics for Linux tasks (processes) : I/O, CPU, memory, etc
  • sar - collects, reports and saves system activity information (CPU, memory, disks, interrupts, network interfaces, TTY, kernel tables, etc)
  • sadc - is the system activity data collector, used as a backend for sar
  • sa1 - collects and stores binary data in the system activity daily data file. It is a front end to sadc designed to be run from cron
  • sa2 - writes a summarized daily activity report. It is a front end to sar designed to be run from cron
  • sadf - displays data collected by sar in multiple formats (CSV, XML, etc.) This is useful to load performance data into a database, or import them in a spreadsheet to make graphs
  • nfsiostat-sysstat - reports input/output statistics for network filesystems (NFS)
  • cifsiostat - reports CIFS statistics

Features include:

  • Monitor:
    • Input / Output and transfer rate statistics (global, per device, per partition, per network filesystem and per Linux task / PID)
    • CPU statistics (global, per CPU and per Linux task / PID), including support for virtualization architectures
    • Memory, hugepages and swap space utilization statistics
    • Virtual memory, paging and fault statistics
    • Per-task (per-PID) memory and page fault statistics
    • Global CPU and page fault statistics for tasks and all their children
    • Process creation activity
    • Interrupt statistics (global, per CPU and per interrupt, including potential APIC interrupt sources, hardware and software interrupts)
    • Extensive network statistics: network interface activity (number of packets and kB received and transmitted per second, etc.) including failures from network devices; network traffic statistics for IP, TCP, ICMP and UDP protocols based on SNMPv2 standards; support for IPv6-related protocols
    • NFS server and client activity
    • Socket statistics
    • Run queue and system load statistics
    • Kernel internal tables utilization statistics
    • System and per Linux task switching activity
    • Swapping statistics
    • TTY device activity
    • Power management statistics (instantaneous and average CPU clock frequency, fans speed, devices temperature, voltage inputs, USB devices plugged into the system)
    • Filesystems utilization (inodes and blocks)
  • Average statistics values are calculated over the sampling period
  • Most system statistics can be saved in a file for future inspection
  • Allows to configure the length of data history to keep
  • On the fly detection of new devices (disks, network interfaces, etc.) that are created or registered dynamically
  • Support for UP and SMP machines, including machines with hyperthreaded or multi-core processors
  • Support for hotplug CPUs (it detects automagically processors that are disabled or enabled on the fly) and tickless CPUs
  • Works on many different architectures, whether 32- or 64-bit
  • Needs very little CPU time to run (written in C)
  • System statistics can be exported in various different formats (CSV, XML, JSON, etc.). DTD and XML Schema documents are included in sysstat package
  • Internationalization support
  • Many programs available on the internet to use sysstat's data to make graphs (one of them, isag, is included in sysstat)
