+# Golang 获取硬件参数及 CPU/内存/硬盘 的使用率
+
+## 1. 安装软件包
+
+```bash
+go get github.com/tklauser/go-sysconf
+go get golang.org/x/sys/unix
+go get github.com/shirou/gopsutil
+```
+
+## 2. 示例代码
+
+```go
+package main
+
+import (
+	"fmt"
+	"time"
+
+	"github.com/shirou/gopsutil/cpu"
+	"github.com/shirou/gopsutil/disk"
+	"github.com/shirou/gopsutil/mem"
+)
+
+func GetCoreCount() int {
+	cpuInfo, _ := cpu.Info()
+	return len(cpuInfo)
+}
+
+func GetModelName(idx int) string {
+	cpuInfo, _ := cpu.Info()
+	return cpuInfo[idx].ModelName
+}
+
+func GetCpuPercent() float64 {
+	percent, _ := cpu.Percent(time.Second, false)
+	return percent[0]
+}
+
+func GetMemPercent() float64 {
+	memInfo, _ := mem.VirtualMemory()
+	return 100.0 * float64(memInfo.Total-memInfo.Available) / float64(memInfo.Total)
+}
+
+func GetDiskPercent() float64 {
+	diskInfo, _ := disk.Usage("/")
+	return diskInfo.UsedPercent
+}
+
+func main() {
+	fmt.Println("Model Name: ", GetModelName(0))
+	fmt.Println("Core count: ", GetCoreCount())
+	for {
+		fmt.Println("CPU: ", GetCpuPercent())
+		fmt.Println("Mem: ", GetMemPercent())
+		fmt.Println("Dsk: ", GetDiskPercent())
+		time.Sleep(1 * time.Second)
+	}
+}
+```
