Question

使用以下代码：https://www.reddit.com/r/PowerShell/comments/3iced0/gettomcat_status/

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

我们在下面看到堆内存：

姓名：PS Eden Space
姓名：PS Old Gen
姓名：PS Survivor Space

我遇到的问题是为Used和Maximum添加所有这三个似乎都是关闭的（方式太高）。

每个人都有堆内存。这是否意味着堆内存是附加的还是包含所有这三个？

让我们展示一些代码：

Add-Content $fileName "</tr>"

     #Return $output

给我带来困难的部分是：

    $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

我想我想出来了..

读。

堆内存：JVM使用此内存来存储对象。这种记忆又分为两个不同的区域，称为“年轻代空间”和“终身空间”。

年轻一代：年轻一代或新太空被分为两个部分，称为“伊甸园空间”和“幸存者空间”。

Eden Space：当我们创建一个对象时，内存将从Eden Space中分配。

阅读本文，我们需要删除：幸存者和老人我们看到了有利的结果。
