wmic cpu get LoadPercentage始终返回空值 [英] wmic cpu get LoadPercentage always returns empty value

问题描述

我正在使用wmic命令获取当前的CPU使用率，该命令是:

I'm use wmic command to get current CPU utilization, the command are:

wmic cpu get LoadPercentage /value

起初它可以正常工作，但是不知何故它没有显示LoadPercentage，但总是返回空结果，如:

It's works fine at first, but somehow it doesn't shows the LoadPercentage, but always returns with empty result like:

C:\Users\Administrator>wmic cpu get LoadPercentage /value


LoadPercentage=

这太奇怪了，我很确定结果与taskmgr.exe不匹配.我也尝试了不带/value的此命令，结果仍然相同.

It's so weird and I'm pretty sure that the result don't match with the taskmgr.exe. I also tried this command without /value, the result is still the same.

我已经在服务器中复制了一个大文件，而TaskManager和wmic中的CPU使用情况如下:

I have copy a large file in my server, and the CPU usage in TaskManager and wmic is like:

无论TaskManager中的值是多少，wmic始终返回空值.

no matter what value is in TaskManager, the wmic always return empty value.

推荐答案

我了解这是对死灵文章的回答.但是由于我在这里看不到任何正确的答案，解决方案是lodctr /R.此命令将重新加载计数器.必须使用大写字母R，小写字母"r"返回错误.还要记住管理员权限.

I understand that this is an answer for a necro post. But as I can't see any correct answer here, the solution is lodctr /R . This command will reload counters. Must use a capital R, lower case 'r' returns an error. Remember Admin Privs as well.
