This is a port of psutil (http:https://pythonhosted.org/psutil/). The challenge is porting all psutil functions on some architectures...

Breaking Changes will comes!

We introduced versioning by using gopkgin. And breaking changes will be introduced at v2. See issue 174 .

• 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.

Note: gopsutil.v2 breaks compatibility. If you want to stay with compatibility, please use gopkg.in/shirou/gopsutil.v1.

import (
     "fmt"

 mem "gopkg.in/shirou/gopsutil.v2/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 /proc by setting the HOST_PROC environment variable. You can set an alternative location to /sys by setting the HOST_SYS environment variable. You can set an alternative location to /etc by setting the HOST_ETC environment variable.

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
• 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.

• x: work
• b: almost work but something broken

• future work
  • process_iter
  • wait_procs
  • Process class
    • as_dict
    • wait

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

My English is terrible, so documentation or correcting comments are also welcome.
