查看CPU的实时运行频率

1、启动ESXi ssh 服务；

 

2、使用ssh工具连接主机；

 

3、执行esxtop;

 

4、依次按p,f,f,回车

 

5、使用A/MPERF列数据*cpu基础频率得到的就是实际频率。例如：我的CPU是Intel Xeon Gold 6230 CPU @ 2.10GHz。cpu0实际频率=133.3%*2.10GHz=2.79GHz

6、说明：

ESXTOP -> P (Power) -> F (Fields) -> F (APerf)%

The %A/MPERF shows the % above base frequency that you are running at per core.

For example:

○ CPU Performance Profile - High Performance

○ E5-2699 v3 (18c) - base frequency 2300 MHz

○ 16vCPU CPUStress VM

Looking at ESXTOP, A/MPERF = 121.7% (per used core)

121.7% * 2300 = 2799.1
