PowerShell中调用，RestMethod问题，需要确定堆内存

在使用代码：https://www.reddit.com/r/PowerShell/comments/3iced0/gettomcat_status/PowerShell中调用，RestMethod问题，需要确定堆内存

如果我们调用以下网址：http://RemoteServer/manager/status?XML=true

我们看到下面的堆内存：

  • 名称：PS Eden Space
  • 产品名称：PS Old Gen
  • 产品名称：PS Survivor Space

我遇到的问题是将所有这三个用于二手和最大似乎是关闭（方式太高）。

每个都有堆内存。这是否意味着堆内存是附加的或者包含所有这三个？

让我们展示一些代码：

    Add-Content $fileName "<td align='center'> $requestInfoprocessingTime </td>" 
Add-Content $fileName "</tr>" 

    #Return $output 
}

的一部分是给我一个困难时期是：

    $memoryEdenUsed = $MemoryEden.usageUsed 
    $memoryOldGenUsed = $MemoryOldGen.usageUsed 
    $memorySurvivorUsed = $MemorySurvivor.usageUsed 
    $memoryHeapUsed = $memoryEdenUsed + $memoryOldGenUsed + $memorySurvivorUsed 
    $memoryHeapUsed = $memoryHeapUsed/1MB 
    $memoryHeapUsed = $memoryHeapUsed.ToString("00.00") 
    Add-Content $fileName "<td align='center'> $memoryHeapUsed MB</td>" 

    $memoryEdenMax = $MemoryEden.usageMax 
    $memoryOldGenMax = $MemoryOldGen.usageMax 
    $memorySurvivorMax = $MemorySurvivor.usageMax 
    $memoryHeapMax = $memoryEdenMax + $memoryOldGenMax + $memorySurvivorMax

我想我想通了..

阅读。

堆内存：JVM使用该存储器来存储对象。这种记忆又分为两个不同的领域，称为“年轻一代空间”和“终身空间”。

年轻一代：年轻一代或新空间被分成两部分，分别叫做“伊甸园空间”和“幸存者空间”。

伊甸园空间：当我们创建一个对象时，内存将从伊甸空间分配。

读这个，我们需要删除： 幸存者和旧 而我们看到有利的结果。

下面是完成代码：

function Get-TomcatStatus{ 
    param(
    $fileName, 
     $tomcatserver ,
