WMI查询 - 多个处理器 - 寻找单个结果 [英] WMI Query - Multiple Processors - Looking for a Single Result

问题描述

大家好， 

Hi all,  

我正在开发一个powershell脚本来提取远程机器信息并将其转储到Excel工作表（用于资产管理/收集）。  道歉有一个冗长的解释，但这是我的思考过程。

I'm working on a powershell script to pull remote machine information and dump it to an Excel worksheet (for asset management/collection).  Apologies for a lengthy explanation, but this is my thought process.

当我查询具有多核/多个cpus的机器时，我遇到的一个错误。

A bug I've run into rears its head when I query a machine with multi-core / multiple-cpus.

如果我这样做：

[math]::Round(((Get-WmiObject win32_processor -ComputerName <computername>).MaxClockSpeed * .001),1)

我收到错误"无法找到"Round"的过载和参数计数："2"。

I get an error "Cannot find an overload for "Round" and the argument count: "2".

我已经确定（这可能有缺陷），这可能是因为查询结果我试图在一行上舍入产生2个单独的值：

I've determined (this may be flawed) that this is likely because the query results I'm attempting to round on a single line produces 2 separate values:

2800

< span class ="x_x_Apple-tab-span"style ="white-space：pre"> 2800

2800
2800

事实上，机器注册了2个CPU，CPU0和CPU1。请参阅以下结果 

The machine in fact registers with 2 CPU's, CPU0 and CPU1. See below the results of 

Get-WmiObject win32_processor -ComputerName <computername>

我试图通过流水线"Where-Object"来减少结果的数量。像这样（我不包括圆形声明，认为在尝试对它运行数学之前获得单个数字结果会更好。）

I attempted to lessen the number of results with a pipelined "Where-Object" like this (I am not including the round statement, figuring that it'd be better to get a single numeric result before attempting to run the math against it).

(Get-WmiObject win32_processor -ComputerName <computername>).MaxClockSpeed | Where-Object {$_.DeviceID -like 'CPU0'}

不幸的是，当我运行它时，而不是从标识为DeviceID"CPU0"的处理器获取MaxClockSpeed结果我什么都没得到。

Unfortunately, when I run this, instead of getting the MaxClockSpeed result from the processor identified as DeviceID "CPU0", I get nothing at all.

我认为这可能是因为我在Where-Object语句中使用了错误的限定符（我试过-eq而不是-like），但是还没有能够超越这一点。

I thought this might be because I'm using the wrong qualifier in the Where-Object statement (I tried -eq instead of -like), but haven't been able to get past this point.

建议，帮助和指针总是*赞赏。

Suggestions, help and pointers are *always* appreciated.

谢谢，

Ben

推荐答案

我想我找到了解决办法。  我管道它并使用select-object指定使用第一个结果。

I think I found my solution.  I pipe it and use select-object specifying to use the first result.

感谢您的观点！  如果您想出一个更优雅的解决方案，请随时回复。

Thanks for the views!  If you come up with a more elegant solution feel free to reply.
