This is a port of psutil (https://github.com/giampaolo/psutil). The challenge is porting all
psutil functions on some architectures.

Breaking Changes! golang 1.8 is required

After v2.17.04, golang 1.8 is required to build.

Tag semantics

gopsutil tag policy is almost same as Semantic Versioning, but automatically increase like Ubuntu versioning.

for example, v2.17.04 means

  • v2: major version
  • 17: release year, 2017
  • 04: release month

gopsutil aims to keep backwards-compatiblity until major version change.

Taged at every end of month, but there are only a few commits, it can be skipped.

Available Architectures

  • FreeBSD i386/amd64/arm
  • Linux i386/amd64/arm(raspberry pi)
  • Windows/amd64
  • Darwin i386/amd64
  • OpenBSD amd64 (Thank you @mpfz0r!)
  • Solaris amd64 (developed and tested on SmartOS/Illumos, Thank you @jen20!)

All works are implemented without cgo by porting c struct to golang struct.

Usage

Note: gopsutil v2 breaks compatibility. If you want to stay with compatibility, please use v1 branch and vendoring.

.. code:: go

package main

import (
"fmt"

   "github.com/shirou/gopsutil/mem"

)

func main() {
v, _ := mem.VirtualMemory()

   // almost every return value is a struct
   fmt.Printf("Total: %v, Free:%v, UsedPercent:%f%%\n", v.Total, v.Free, v.UsedPercent)

   // convert to JSON. String() is also implemented
   fmt.Println(v)

}

The output is below.

::

Total: 3179569152, Free:284233728, UsedPercent:84.508194%
{"total":3179569152,"available":492572672,"used":2895335424,"usedPercent":84.50819439828305, (snip...)}

You can set an alternative location to :code:/proc by setting the :code:HOST_PROC environment variable.

You can set an alternative location to :code:/sys by setting the :code:HOST_SYS environment variable.

You can set an alternative location to :code:/etc by setting the :code:HOST_ETC environment variable.

You can set an alternative location to :code:/var by setting the :code:HOST_VAR environment variable.

You can set an alternative location to :code:/run by setting the :code:HOST_RUN environment variable.

You can set an alternative location to :code:/dev by setting the :code:HOST_DEV environment variable.

Requirements

  • go1.7 or above is required.

More Info

Several methods have been added which are not present in psutil, but will provide useful information.

  • host/HostInfo() (linux)

    • Hostname
    • Uptime
    • Procs
    • OS (ex: "linux")
    • Platform (ex: "ubuntu", "arch")
    • PlatformFamily (ex: "debian")
    • PlatformVersion (ex: "Ubuntu 13.10")
    • VirtualizationSystem (ex: "LXC")
    • VirtualizationRole (ex: "guest"/"host")

  • IOCounters

    • Label (linux only) The registered device mapper name <https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-block-dm>_

  • cpu/CPUInfo() (linux, freebsd)

    • CPU (ex: 0, 1, ...)
    • VendorID (ex: "GenuineIntel")
    • Family
    • Model
    • Stepping
    • PhysicalID
    • CoreID
    • Cores (ex: 2)
    • ModelName (ex: "Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz")
    • Mhz
    • CacheSize
    • Flags (ex: "fpu vme de pse tsc msr pae mce cx8 ...")
    • Microcode

  • load/LoadAvg() (linux, freebsd)

    • Load1
    • Load5
    • Load15

  • docker/GetDockerIDList() (linux only)

    • container id list ([]string)

  • docker/CgroupCPU() (linux only)

    • user
    • system

  • docker/CgroupMem() (linux only)

    • various status

  • net_protocols (linux only)

    • system wide stats on network protocols (i.e IP, TCP, UDP, etc.)
    • sourced from /proc/net/snmp

  • iptables nf_conntrack (linux only)

    • system wide stats on netfilter conntrack module
    • sourced from /proc/sys/net/netfilter/nf_conntrack_count

Some codes are ported from Ohai. many thanks.
