This is a port of psutil(http://pythonhosted.org/psutil/). This
challenges porting all psutil functions on some architectures.
Available archtectures
------------------------------------
- FreeBSD/amd64
- Linux/amd64
- Linux/arm (raspberry pi)
- Windows/amd64
(I do not have a darwin machine)
All works are implemented without cgo by porting c struct to golang struct.
Usage
---------
::
import (
"fmt"
"github.com/shirou/gopsutil"
)
func main() {
v, _ := gopsutil.VirtualMemory()
// almost every return value is 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(d)
}
The output is below.
::
Total: 3179569152, Free:284233728, UsedPercent:84.508194%
{"total":3179569152,"available":492572672,"used":2895335424,"usedPercent":84.50819439828305, (snip)}

More info
--------------------
To becomes more useful, add more information.
- Hostinfo() (linux)
- OS
- Platform ex: ubuntu, arch
- Platform family ex: debian
- Platform Version ex: Ubuntu 13.10
- CPUInfoStat() (linux, freebsd)
- Processer
- Vendor ID

Some codes are ported some functions from Ohai. very thanks.
