[TOC] ## 概述 安裝 ``` go get github.com/shirou/gopsutil ``` ### 使用 #### CPU 采集CPU相關信息。 ``` import "github.com/shirou/gopsutil/cpu" // cpu info func getCpuInfo() { cpuInfos, err := cpu.Info() if err != nil { fmt.Printf("get cpu info failed, err:%v", err) } for _, ci := range cpuInfos { fmt.Println(ci) } // CPU使用率 for { percent, _ := cpu.Percent(time.Second, false) fmt.Printf("cpu percent:%v\n", percent) } } ``` 獲取CPU負載信息： ``` import "github.com/shirou/gopsutil/load" func getCpuLoad() { info, _ := load.Avg() fmt.Printf("%v\n", info) } ``` #### Memory ``` import "github.com/shirou/gopsutil/mem" // mem info func getMemInfo() { memInfo, _ := mem.VirtualMemory() fmt.Printf("mem info:%v\n", memInfo) } ``` #### Host ``` import "github.com/shirou/gopsutil/host" // host info func getHostInfo() { hInfo, _ := host.Info() fmt.Printf("host info:%v uptime:%v boottime:%v\n", hInfo, hInfo.Uptime, hInfo.BootTime) } ``` #### Disk ``` import "github.com/shirou/gopsutil/disk" // disk info func getDiskInfo() { parts, err := disk.Partitions(true) if err != nil { fmt.Printf("get Partitions failed, err:%v\n", err) return } for _, part := range parts { fmt.Printf("part:%v\n", part.String()) diskInfo, _ := disk.Usage(part.Mountpoint) fmt.Printf("disk info:used:%v free:%v\n", diskInfo.UsedPercent, diskInfo.Free) } ioStat, _ := disk.IOCounters() for k, v := range ioStat { fmt.Printf("%v:%v\n", k, v) } } ``` #### net IO ``` import "github.com/shirou/gopsutil/net" func getNetInfo() { info, _ := net.IOCounters(true) for index, v := range info { fmt.Printf("%v:%v send:%v recv:%v\n", index, v, v.BytesSent, v.BytesRecv) } } ``` #### 獲取本機IP的兩種方式 ``` func GetLocalIP() (ip string, err error) { addrs, err := net.InterfaceAddrs() if err != nil { return } for _, addr := range addrs { ipAddr, ok := addr.(*net.IPNet) if !ok { continue } if ipAddr.IP.IsLoopback() { continue } if !ipAddr.IP.IsGlobalUnicast() { continue } return ipAddr.IP.String(), nil } return } ``` 或： ``` // Get preferred outbound ip of this machine func GetOutboundIP() string { conn, err := net.Dial("udp", "8.8.8.8:80") if err != nil { log.Fatal(err) } defer conn.Close() localAddr := conn.LocalAddr().(*net.UDPAddr) fmt.Println(localAddr.String()) return localAddr.IP.String() } ```
