Go语言 获取服务器资源磁盘Disk情况

 1、获取整个磁盘的总量、已使用量、使用率

package mainimport ("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 uint64var used uint64for _, 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.Totalused += 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)}
