gopsutil: psutil for golang
==============================
.. image:: https://drone.io/github.com/shirou/gopsutil/status.png
:target: https://drone.io/github.com/shirou/gopsutil
.. image:: https://coveralls.io/repos/shirou/gopsutil/badge.png?branch=master
:target: https://coveralls.io/r/shirou/gopsutil?branch=master
This is a port of psutil (http://pythonhosted.org/psutil/). The challenge is porting all
psutil functions on some architectures...
.. highlights:: Package Structure Changed!
Package (a.k.a. directory) structure has been changed!! see `issue 24 <https://github.com/shirou/gopsutil/issues/24>`_
.. highlights:: golang 1.4 will become REQUIRED!
Since syscall package becomes frozen, we should use golang/x/sys of golang 1.4 as soon as possible.
Available Architectures
------------------------------------
- FreeBSD i386/amd64
- Linux i386/amd64/arm(raspberry pi)
- Windows/amd64
- Darwin/amd64
All works are implemented without cgo by porting c struct to golang struct.
Usage
---------
.. code:: go
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)}
Documentation
------------------------
see http://godoc.org/github.com/shirou/gopsutil
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")
- 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 ...")
- 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
Some codes are ported from Ohai. many thanks.
