GO语言本身拥有极强的性能,非常适合做一些后端的数据采集管理以及运维系统。
其中会面临对当前系统信息的采集,我在这里使用的是GO的工具包 gopsutil
贴出一套测试代码,抛砖引玉:
import ( "fmt"
"time"
"github.com/shirou/gopsutil/cpu"
"github.com/shirou/gopsutil/disk"
"github.com/shirou/gopsutil/host"
"github.com/shirou/gopsutil/mem"
"github.com/shirou/gopsutil/net")
func collet() {
v, _ := mem.VirtualMemory()
c, _ := cpu.Info()
cc, _ := cpu.Percent(time.Second, false)
d, _ := disk.Usage("/")
n, _ := host.Info()
nv, _ := net.IOCounters(true)
boottime, _ := host.BootTime()
btime := time.Unix(int64(boottime), 0).Format("2006-01-02 15:04:05")
fmt.Printf(" Mem : %v MB Free: %v MB Used:%v Usage:%f%%\n", v.Total/1024/1024, v.Available/1024/1024, v.Used/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(" Network: %v bytes / %v bytes\n", nv[0].BytesRecv, nv[0].BytesSent)
fmt.Printf(" SystemBoot:%v\n", btime)
fmt.Printf(" CPU Used : used %f%% \n", cc[0])
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) %v \n", n.Platform, n.PlatformFamily, n.PlatformVersion)
fmt.Printf(" Hostname : %v \n", n.Hostname)
}
代码中还包含CPU使用率采集,可用内存采集以及网络数据包收发采集,目前网络数据采集尚不稳定。
