systats

Go module to get linux system stats.

Provides following information on systems:

• System
  • Returns OS, Hostname, Kernel, Up time, last boot date, timezone, logged in users list
• CPU
  • CPU model, freq, load average (overall, per core), etc
• Memory/SWAP
• Disks
  • File system, type, mount point, usage, inodes
• Networks
  • Interface, IP, Rx/Tx
• Service status
  • Returns if given service is active or not
• Processes
  • Returns list of processes sorted by CPU/Memory usage (with PID, exec path, user, usage)

Usage

Import the module

import (
	"github.com/dhamith93/systats"
)

func main() {
    syStats := systats.New()
}

And use the methods to get the required and supported system stats.

System

Returns OS, Hostname, Kernel, Up time, last boot date, timezone, logged in users list

func main() {
	syStats := systats.New()
	system, err := systats.GetSystem()
}

CPU

CPU info and load avg info (overall, and per core)

func main() {
	syStats := systats.New()
	cpu, err := systats.GetCPU()
}

Memory

func main() {
	syStats := systats.New()
	memory, err := systats.GetMemory(systats.Megabyte)
}

SWAP

func main() {
	syStats := systats.New()
	swap, err := systats.GetSwap(systats.Megabyte)
}

Disks

func main() {
	syStats := systats.New()
	disks, err := syStats.GetDisks()
}

Networks

Interface info and usage info

func main() {
	syStats := systats.New()
	networks, err := syStats.GetNetworks()
}

Service status

Returns if service is running or not

func main() {
	syStats := systats.New()
	running := syStats.IsServiceRunning(service)
	if !running {
		fmt.Println(service + " not running")
	}
}

Running processes

Returns running processes sorted by CPU or memory usage

func main() {
	syStats := systats.New()
	procs, err := syStats.GetTopProcesses(10, "cpu")
	procs, err := syStats.GetTopProcesses(10, "memory")
}
