關于擷取windows系統參數方法

  前一陣寫了一個擷取網絡内主機類型的腳本，沒有寫任何解釋類的說明直接發上來造成好多兄弟們有很多疑問。今天就揀幾個有特點的功能說明一下。

   擷取windows系統或者性能參數。

   在powershell出現之前系統管理者習慣用VB來實作擷取以上參數的功能（當然現在也可以），但本次文章的重點主是說powershell怎麼實作擷取以上參數資訊，Powershell提供了很多擴充的功能可以直接通路.net架構，WMI，COM自動化和API的調用等。

   下面我們舉例說明一哈通過WMI擷取主機的記憶體資訊：

   1擷取本地主機空餘記憶體大小：

1

2

<code>[PS]</code> <code>C:\&gt;(GWMI win32_OperatingSystem).FreePhysicalMemory</code>

<code>1245384</code>

   2擷取本地主機的總記憶體大小：

<code>[PS]</code> <code>C:\&gt;(GWMI win32_OperatingSystem).TotalVisibleMemorySize</code>

<code>4166596</code>

   3如果我們想檢視還能檢視還有哪些類可以擷取，按如下操作就可以看到：

  4 如果我們想擷取遠端主機的參數應該怎麼操作呢隻需加上-computer參數比如：

<code>[PS]</code> <code>C:\&gt;(GWMI</code> <code>-computer</code> <code>bjexfe01  win32_OperatingSystem).TotalVisibleMemorySize</code>

<code>33543988</code>
