addresses a few things: - Windows has a concept of both a network "interface" and an "adapter" - These are almost always a one-to-one relationship, though there can be esoteric instances where they are not. - I believe the gopsutil NetIOCounters function should only return on a per-interface level, since this is the behavior on linux/darwin. Previously, the plugin was basically ignoring the actual interfaces returned from net.Interfaces(). Instead, it was looping over the net adapters for each interface, somewhat uselessly. FWIW, the code for getAdapterList() doesn't exist in the Go standard lib anymore. closes #245 |

This is a port of psutil (http://pythonhosted.org/psutil/). The challenge is porting all
psutil functions on some architectures.
.. highlights:: Breaking Changes!
Breaking changes is introduced at v2. See `issue 174 <https://github.com/shirou/gopsutil/issues/174>`_ .
Migrating to v2
-------------------------
On gopsutil itself, `v2migration.sh <https://github.com/shirou/gopsutil/blob/v2/v2migration.sh>`_ is used for migration. It can not be commonly used, but it may help you with migration.
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
---------
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.
Documentation
------------------------
see http://godoc.org/github.com/shirou/gopsutil
Requirements
-----------------
- go1.5 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")
- 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.
