使用PowerShell获取特定进程的CPU％

Question

我想使用powershell命令获取特定进程的CPU使用率％（而不是处理器时间）。

示例：（Windows 8任务管理器）

我希望用命令获取2.9%。

Answer 1

以下是支持案例的正确答案，那么您有多个具有相同名称的进程https://stackoverflow.com/a/34844682/483997

# To get the PID of the process (this will give you the first occurrance if multiple matches)
$proc_pid = (get-process "slack").Id[0]

# To match the CPU usage to for example Process Explorer you need to divide by the number of cores
$cpu_cores = (Get-WMIObject Win32_ComputerSystem).NumberOfLogicalProcessors

# This is to find the exact counter path, as you might have multiple processes with the same name
$proc_path = ((Get-Counter "\Process(*)\ID Process").CounterSamples | ? {$_.RawValue -eq $proc_pid}).Path

# We now get the CPU percentage
$prod_percentage_cpu = [Math]::Round(((Get-Counter ($proc_path -replace "\\id process$","\% Processor Time")).CounterSamples.CookedValue) / $cpu_cores)

Answer 2

Get-Process -Name PowerShell | Select CPU

这是你要找的吗？ 还是更基于监控的东西？

param
(
   [String]
   [Parameter(Mandatory)]
   $Title
)

do
{
   $process = Get-Process -Name $Title
   $process
   Start-Sleep -Seconds 1
} while ($process)

Answer 3

Get-Process -Name系统|选择CPU

获取2实例的cpu时间为（cpu2-cpu1）/（t2-t1）* 100。您将获得％的CPU值。
