【问题描述】：

我正在尝试获取有关 iis 请求的信息，但是当我尝试通过以下方式获取计数器性能时：

Get-WmiObject Win32_PerfRawData_ASP_ActiveServerPages

我收到以下错误：

Get-WmiObject : Invalid class
At line:1 char:21
+ $totob=Get-WmiObject <<<<  Win32_PerfRawData_ASP_ActiveServerPages
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

【参考方案1】：

性能计数器库可能会损坏并且必须重新构建。

这篇知识库文章描述了重建计数器库的过程。

【参考方案2】：

首先你在哪个系统上试验这个问题？

你可以试试：

Get-WMIObject -List| Where$_.name -match "^Win32_.*_ASP.*" | Sort Name | Format-Table name

这是我的 W2K8R2 服务器上的结果：

Win32_PerfFormattedData_ASP_ActiveServerPages
Win32_PerfFormattedData_ASPNET_ASPNET
Win32_PerfFormattedData_ASPNET_ASPNETApplications
Win32_PerfFormattedData_ASPNET2050727_ASPNETAppsv2050727

服务 W3SVC 未运行的地方。
