Merge pull request #1205 from mmorel-35/master enable more linters, report coverage and cache mods
This is a port of psutil (https://github.com/giampaolo/psutil). The challenge is porting all psutil functions on some architectures.
from v3.20.10, gopsutil becomes v3 which breaks backwards compatiblity. See v3Changes.md more detail changes.
gopsutil tag policy is almost same as Semantic Versioning, but automatically increase like Ubuntu versioning.
for example, v2.17.04 means
gopsutil aims to keep backwards-compatiblity until major version change.
Tagged at every end of month, but if there are only a few commits, it can be skipped.
These have partial support:
All works are implemented without cgo by porting C structs to golang structs.
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.

Several methods have been added which are not present in psutil, but will provide useful information.
Some code is ported from Ohai. many thanks.
