在powershell中按CPU使用百分比列出进程 [英] Listing processes by CPU usage percentage in powershell

问题描述

如何通过将 Get-Process 的输出传送到 Where-Object 来列出使用 CPU > 1% 的进程?

How does one lists the processes using CPU > 1% by piping the output from Get-Process to Where-Object?

我能想到的完全是powershell的初学者

Complete beginner to powershell all i can think is something like this

Get-Process | Where-Object { CPU_Usage -gt 1% }

推荐答案

如果你想要 CPU 百分比，你可以使用 Get-Counter 来获取性能计数器，Get-Counter 可以为所有进程运行.因此，要列出 CPU 使用率超过 5% 的进程:

If you want CPU percentage, you can use Get-Counter to get the performance counter and Get-Counter can be run for all processes. So, to list processes that use greater than say 5% of CPU use:

(Get-Counter '\Process(*)\% Processor Time').CounterSamples | Where-Object {$_.CookedValue -gt 5}

这将列出在采样实例中使用超过 5% CPU 的进程.希望这会有所帮助！

This will list the processes that was using >5% of CPU at the instance the sample was taken. Hope this helps!
