powershell - Powershell 的 get-counters cmdlet 中返回的 "cooked value"是什么？

Question

我正在使用 Powershell 返回某些性能计数器的值，并且在显示信息时我看到它指的是“Cookedvalues”。我正在寻找要单独报告的每个计数器命中，因此我可以进行分析，例如查看第 90 个百分位值或最大值/最小值，因此我需要知道它是如何达到熟值的。这是我目前正在使用的代码:

$computer         = $ENV:Computername 
$instance         = "_total" 

@("\\$Computer\PhysicalDisk(*)\Current Disk Queue Length", 
  "\\$Computer\PhysicalDisk(*)\% Disk Time", 
  "\\$Computer\PhysicalDisk(*)\Avg. Disk Queue Length", 
  "\\$Computer\PhysicalDisk(*)\Avg. Disk Read Queue Length", 
  "\\$Computer\PhysicalDisk(*)\Avg. Disk Write Queue Length", 
  "\\$Computer\PhysicalDisk(*)\Avg. Disk sec/Transfer" 
  "\\$Computer\PhysicalDisk(*)\Avg. Disk sec/Read", 
  "\\$Computer\PhysicalDisk(*)\Avg. Disk sec/Write") |% { 
    (Get-Counter $_.replace("*",$instance)).CounterSamples } | 
    Select-Object Path,CookedValue | 
    Format-Table -AutoSize 


#   Retrieve the current Processor performance counter information. 
$computer         = $ENV:Computername 
$instance         = "_total" 
@("\\$Computer\Processor(*)\% Processor Time", 
  "\\$Computer\Processor(*)\% User Time", 
  "\\$Computer\Processor(*)\% Privileged Time", 
  "\\$Computer\Processor(*)\Interrupts/sec", 
  "\\$Computer\Processor(*)\% DPC Time", 
  "\\$Computer\Processor(*)\DPCs Queued/sec" 
  "\\$Computer\Processor(*)\% Idle Time", 
  "\\$Computer\Processor(*)\% Interrupt Time") |% { 
    (Get-Counter $_.replace("*",$instance)).CounterSamples } | 
    Select-Object Path,CookedValue | 
    Format-Table -AutoSize 

# Retreive the current Memory counter information 
$computer         = $ENV:Computername 
$instance         = "_total" 
@("\\$Computer\Memory\Page Faults/sec", 
  "\\$Computer\Memory\Available Bytes", 
  "\\$Computer\Memory\Committed Bytes", 
  "\\$Computer\Memory\Commit Limit", 
  "\\$Computer\Memory\Pages/sec", 
  "\\$Computer\Memory\Free System Page Table Entries" 
  "\\$Computer\Memory\Pool Paged Resident Bytes", 
  "\\$Computer\Memory\Available MBytes") |% { 
    (Get-Counter $_.replace("*",$instance)).CounterSamples } | 
    Select-Object Path,CookedValue | 
    Format-Table -AutoSize

根据 https://blogs.technet.com/b/nexthop/archive/2011/06/02/gpsperfcounters.aspx ，“CookedValue”是:

performance counters typically have raw values, second values, and cooked values. The raw values and second values are the raw ingredients used by the performance counter, and the "cooked value" is the result of "cooking" those ingredients into something for human consumption.

显然， CookedValue 是组合计数器的原始数据以获得您可以理解和使用的可用值的结果。
