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{})// 获取主机相关信息hostInfo, _ := host.Info()hostMap := make(map[string]interface{})hostMap["uptime"] = hostInfo.Uptime                   //运行时间hostMap["bootTime"] = hostInfo.BootTime               //启动时间hostMap["procs"] = hostInfo.Procs                     //进程数hostMap["os"] = hostInfo.OS                           //操作系统hostMap["platform"] = hostInfo.Platform               //平台hostMap["platformVersion"] = hostInfo.PlatformVersion //平台版本hostMap["kernelArch"] = hostInfo.KernelArch           //内核hostMap["kernelVersion"] = hostInfo.KernelVersion     //内核版本statMap["hosts"] = hostMap// 获取内存信息memInfo, _ := mem.VirtualMemory()memMap := make(map[string]interface{})memMap["total"] = memInfo.Total             //总内存memMap["available"] = memInfo.Available     //可用内存memMap["used"] = memInfo.Used               //已使用内存memMap["free"] = memInfo.Free               //剩余内存memMap["usedPercent"] = memInfo.UsedPercent //百分比memMap["buffers"] = memInfo.Buffers         //缓存memMap["shared"] = memInfo.Shared           //共享内存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ioInfo, _ := net.IOCounters(false)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"] = diskMapArrutil.R(c, nil, statMap)})}

调用接口，查看接口响应数据
