没事逛 github ，发现 python 上收集系统信息的著名模块 psutil 已经有 go 的版本，迫不及待下载下来把玩一下。

github 上的地址是 https://github.com/shirou/gopsutil

显示本机的一些基本信息package main import ( "fmt" "github.com/shirou/gopsutil/cpu" "github.com/shirou/gopsutil/disk" "github.com/shirou/gopsutil/host" "github.com/shirou/gopsutil/mem" ) func main() { v, _ := mem.VirtualMemory() c, _ := cpu.CPUInfo() d, _ := disk.DiskUsage("/") n, _ := host.HostInfo() fmt.Printf(" Mem : %v GB Free: %v MB Usage:%f%%\n", v.Total/4/1024/1024/1024/1024, v.Free/4/1024/1024/1024, v.UsedPercent) if len(c) > 1 { for _, sub_cpu := range c { modelname := sub_cpu.ModelName cores := sub_cpu.Cores fmt.Printf(" CPU : %v %v cores \n", modelname, cores) } } else { sub_cpu := c[0] modelname := sub_cpu.ModelName cores := sub_cpu.Cores fmt.Printf(" CPU : %v %v cores \n", modelname, cores) } fmt.Printf(" HD : %v GB Free: %v GB Usage:%f%%\n", d.Total/1024/1024/1024, d.Free/1024/1024/1024, d.UsedPercent) fmt.Printf(" OS : %v %v \n", n.OS, n.PlatformVersion) fmt.Printf(" Hostname : %v \n", n.Hostname) }

运行结果如下：

$ status Mem : 8 GB Free: 0 MB Usage:99.999886% CPU : Intel(R) Core(TM) i5-4278U CPU @ 2.60GHz 2 cores HD : 111 GB Free: 39 GB Usage:64.653732% Hostname : waitfishdeMacBook-Pro.local OS_Version: 14.1.0
