# gopsutil: psutil for golang

[![Test](https://github.com/shirou/gopsutil/actions/workflows/test.yml/badge.svg)](https://github.com/shirou/gopsutil/actions/workflows/test.yml) [![Coverage Status](https://coveralls.io/repos/github/shirou/gopsutil/badge.svg?branch=master)](https://coveralls.io/github/shirou/gopsutil?branch=master) [![Go Reference](https://pkg.go.dev/badge/github.com/shirou/gopsutil/v3.svg)](https://pkg.go.dev/github.com/shirou/gopsutil/v3) [![Go Documentation](https://godocs.io/github.com/shirou/gopsutil/v3?status.svg)](https://godocs.io/github.com/shirou/gopsutil/v3) [![Calendar Versioning](https://img.shields.io/badge/calver-vMAJOR.YY.MM-22bfda.svg)](https://calver.org/)

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

## v3 migration

From v3.20.10, gopsutil becomes v3 which breaks backwards compatibility.
See [v3Changes.md](_tools/v3migration/v3Changes.md) for more detailed changes.

## Tag semantics

gopsutil tag policy is almost same as Semantic Versioning, but
automatically increases like [Ubuntu versioning](https://calver.org/).

For example, v2.17.04 means

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

gopsutil aims to keep backwards compatibility until major version change.

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

## Available Architectures

- FreeBSD i386/amd64/arm
- Linux i386/amd64/arm(raspberry pi)
- Windows i386/amd64/arm/arm64
- Darwin amd64/arm64
- OpenBSD i386/amd64/armv7/arm64/riscv64 (Thank you @mpfz0r!)
- Solaris amd64 (developed and tested on SmartOS/Illumos, Thank you
  @jen20!)

These have partial support:

- CPU on DragonFly BSD (#893, Thank you @gballet!)
- host on Linux RISC-V (#896, Thank you @tklauser!)

All works are implemented without cgo by porting C structs to golang
structs.

## Usage

```go
package main

import (
    "fmt"

"github.com/shirou/gopsutil/v3/mem"
    // "github.com/shirou/gopsutil/mem"  // to use v2
)

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.

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

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

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

You can set an alternative location to `/` by setting the `HOST_ROOT`
environment variable.

You can set an alternative location to `/proc/N/mountinfo` by setting the
`HOST_PROC_MOUNTINFO` environment variable.

### Adding settings using `context` (from v3.23.6)

As of v3.23.6, it is now possible to pass a path location using `context`: import `"github.com/shirou/gopsutil/v3/common"` and pass a context with `common.EnvMap` set to `common.EnvKey`, and the location will be used within each function.

```
	ctx := context.WithValue(context.Background(), 
		common.EnvKey, common.EnvMap{common.HostProcEnvKey: "/myproc"},
	)
	v, err := mem.VirtualMemoryWithContext(ctx)
```

First priority is given to the value set in `context`, then the value from the environment variable, and finally the default location.

### Caching

As of v3.24.1, it is now possible to cached some values. These values default to false, not cached.

Be very careful that enabling the cache may cause inconsistencies. For example, if you enable caching of boottime on Linux, be aware that unintended values may be returned if [the boottime is changed by NTP after booted](https://github.com/shirou/gopsutil/issues/1070#issuecomment-842512782).

- `host`
  - EnableBootTimeCache
- `process`
  - EnableBootTimeCache

## Documentation

See https://pkg.go.dev/github.com/shirou/gopsutil/v3 or https://godocs.io/github.com/shirou/gopsutil/v3

## Requirements

- go1.18 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/Avg() (linux, freebsd, solaris)
  - 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 code is ported from Ohai. Many thanks.

## Current Status

- x: works
- b: almost works, but something is broken
- c: works in CGO only
