Golang System Info Guide

To obtain system information, you can utilize the runtime package and os package in the Go language.

Here are some ways to obtain system information:

1. Obtain the name and architecture of the operating system:

package main

import (
	"fmt"
	"runtime"
)

func main() {
	fmt.Println("操作系统：", runtime.GOOS)
	fmt.Println("架构：", runtime.GOARCH)
}

1. Retrieve the number of CPU cores:

package main

import (
	"fmt"
	"runtime"
)

func main() {
	fmt.Println("CPU核心数：", runtime.NumCPU())
}

1. Get memory information.

package main

import (
	"fmt"
	"runtime"
)

func main() {
	var memStats runtime.MemStats
	runtime.ReadMemStats(&memStats)

	fmt.Println("总分配的内存：", memStats.TotalAlloc)
	fmt.Println("堆内存使用量：", memStats.HeapAlloc)
	fmt.Println("堆内存释放量：", memStats.HeapReleased)
	fmt.Println("堆内存对象数：", memStats.HeapObjects)
}

1. Accessing environmental variables:

package main

import (
	"fmt"
	"os"
)

func main() {
	envVars := os.Environ()
	for _, envVar := range envVars {
		fmt.Println(envVar)
	}
}

These methods can assist you in obtaining information about the operating system, hardware, and environment.
