用Java查找Windows计算机的平均CPU使用率 [英] Finding the average CPU usage for Windows machine in Java

问题描述

我已经在互联网上搜索了大约两天。我发现了很多有关如何使用VB和.NET框架中的内容查找CPU使用率的信息。我感觉我没有使用.NET框架，所以它们是无关紧要的。

我真正需要的是与 CPU使用情况部分中显示的结果相似的结果。 性能选项卡下的Windows任务管理器。如果我能找到一种模仿该计算的方法，那正是我所寻找的。我需要CPU使用率的百分比。

显然，Java不是查找计算机CPU使用率的理想语言，但这是我和我正在使用的语言。

我正在使用Windows 7和Java 7更新21。Eclipse是我的IDE。

这是我第一次在此处发布问题，因此，如果我遗漏了任何东西或有不清楚的地方，请询问，我将尽力解释更多信息

解决方案

有两种方法可以做到这一点。一种是运行命令行工具并解析输出。在Windows 7上，您可以运行

  c：\Windows\system32\typeperf \processor（_total）＼ processor％的处理器时间 
  

尝试一下-打印几行采样的CPU负载数据。 / p>

另一种方法是使用 OperatingSystemMXBean 。

I have searched all over the internet for about two days now. I have found a lot about how to find the CPU usage using VB and anything in the .NET framework. I am not using the .NET framework so these are irrelevant, I feel.

What I really need is results similar to the ones shown in the "CPU Usage" section in a Windows Task Manager under the "Performance" tab. If I could find a way to mimic that calculation, then that is exactly what I am looking for. I need the percentage of CPU Usage.

Obviously, Java is not the ideal language for finding the CPU usage of a computer, but that is the language I am using and I have been able to get everything else I need about the computer except this.

I am using Windows 7 with Java version 7 update 21. Eclipse is my IDE.

This is my first time posting a question on here, so if I have left anything out or something is not clear, please ask and I will do my best to explain more of what I mean.

解决方案

There are a couple of ways to do this; one is to run a command-line tool and parse the output. On Windows 7, you can run

c:\Windows\system32\typeperf "\processor(_total)\% processor time"

Try it -- it prints a few lines of sampled CPU load data.

Another way is to use OperatingSystemMXBean .
