工业制造领涉及的8大常见管理系统，如mes、scada、aps、wms等

 1、获取整个磁盘的总量、已使用量、使用率

package main

import (
	"fmt"
	"github.com/shirou/gopsutil/disk"
	"log"
)

func main() {
	// 获取所有挂载点的磁盘使用率信息
	partitions, err := disk.Partitions(false)
	if err != nil {
		log.Fatalf("Error getting partitions: %v", err)
	}

	var total uint64
	var used uint64

	for _, partition := range partitions {
		usage, err := disk.Usage(partition.Mountpoint)
		if err != nil {
			log.Printf("Error getting usage for %s: %v", partition.Mountpoint, err)
			continue
		}

		total += usage.Total
		used += usage.Used
	}

	// 计算总使用率
	usagePercent := float64(used) / float64(total) * 100

	// 打印总磁盘使用率信息
	fmt.Printf("Total Disk Usage: %.2f%%\n", usagePercent)
	fmt.Printf("Total: %v GB\n", total/1024/1024/1024)
	fmt.Printf("Used: %v GB\n", used/1024/1024/1024)
	fmt.Printf("Free: %v GB\n", (total-used)/1024/1024/1024)
}

2、获取某个目录的空间总量、剩余量、使用量、使用率

比如：下面的查询根目录的空间大小、剩余空间、使用空间、使用绿

	package main

	"github.com/shirou/gopsutil/disk"
	)

	func main() {
		// 获取磁盘使用率信息
		usage, err := disk.Usage("/")
		if err != nil {
			fmt.Printf("Error getting disk usage: %v\n", err)
			return
		}

		// 打印磁盘使用率信息
		fmt.Printf("Disk Usage of /:\n")
		fmt.Printf("Total: %v GB\n", usage.Total/1024/1024/1024)
		fmt.Printf("Free: %v GB\n", usage.Free/1024/1024/1024)
		fmt.Printf("Used: %v GB\n", usage.Used/1024/1024/1024)
		fmt.Printf("Used Percent: %.2f%%\n", usage.UsedPercent)
	}
