使用

#下载包
go get github.com/shirou/gopsutil/v3/cpu
go get github.com/shirou/gopsutil/v3/disk
go get github.com/shirou/gopsutil/v3/host
go get github.com/shirou/gopsutil/v3/mem
go get github.com/shirou/gopsutil/v3/net

使用gin定义接口

hostRouters := r.Group("/host", func(context *gin.Context) {})
	{
		hostRouters.GET("stats", func(c *gin.Context) {
			statMap := make(map[string]interface{})

			hostMap["kernelArch"] = hostInfo.KernelArch           //内核
			hostMap["kernelVersion"] = hostInfo.KernelVersion     //内核版本

			// 获取内存信息

			memMap["cached"] = memInfo.Cached           //缓冲区
			statMap["mems"] = memMap

			// 获取CPU信息
			cpuInfo, _ := cpu.Info()
			var cpuMapArr []map[string]interface{}
			for _, c := range cpuInfo {
				cpuMap := make(map[string]interface{})
				cpuMap["cpu"] = c.CPU + 1         //第几个CPU 从0开始的
				cpuMap["cores"] = c.Cores         //CPU的核数
				cpuMap["modelName"] = c.ModelName //CPU类型
				cpuMapArr = append(cpuMapArr, cpuMap)
			}
			statMap["cpus"] = cpuMapArr

			// 获取IO信息

			var ioMapArr []map[string]interface{}
			for _, i := range ioInfo {
				ioMap := make(map[string]interface{})
				ioMap["ioName"] = i.Name             //网口名
				ioMap["bytesSent"] = i.BytesSent     //发送字节数
				ioMap["bytesRecv"] = i.BytesRecv     //接收字节数
				ioMap["packetsSent"] = i.PacketsSent //发送的数据包数
				ioMap["packetsRecv"] = i.PacketsRecv //接收的数据包数
				ioMapArr = append(ioMapArr, ioMap)
			}
			statMap["ios"] = ioMapArr

			// 获取磁盘信息
			partitions, _ := disk.Partitions(false)
			var diskMapArr []map[string]interface{}
			for _, partition := range partitions {
				diskMap := make(map[string]interface{})
				usage, _ := disk.Usage(partition.Mountpoint)
				diskMap["disk"] = partition.Mountpoint     //第几块磁盘
				diskMap["total"] = usage.Total             //总大小
				diskMap["free"] = usage.Free               //剩余空间
				diskMap["used"] = usage.Used               //已使用空间
				diskMap["usedPercent"] = usage.UsedPercent //百分比
				diskMapArr = append(diskMapArr, diskMap)
			}
			statMap["disks"] = diskMapArr

			util.R(c, nil, statMap)
		})
