超时 Get-WMIObject cmdlet [英] Timeout Get-WMIObject cmdlet

问题描述

我运行了一个执行许多 WMI 查询的脚本 - 但如果服务器没有回答，cmdlet 就会挂起.如果 X 秒过去了，我有什么办法可以使这个(或任何其他与此相关的 cmdlet)超时并退出?

I run a script which performs many WMI-querys - but the cmdlet hangs if the server doesn't answer.. Is there any way I can make this (or any other cmndlet for that matter) timeout and exit if X seconds has passed?

编辑

感谢 mjolinor 的提示，解决方案是将其作为 -asjob 运行并在 while 循环中设置超时.但这已经从作业中运行(从 Start-Job 开始).那么我怎么知道我正在控制正确的工作?

Thanks to a tip from mjolinor the solution is to run this as -asjob and set a timeout in a while loop. But this is run from within a job already (started with Start-Job). So how do I know I am controlling the correct job?

这是我已经开始的工作中的代码:

This is my code from inside my already started job:

Get-WmiObject Win32_Service -ComputerName $server -AsJob

$Complete = Get-date

While (Get-Job -State Running){
    If ($(New-TimeSpan $Complete $(Get-Date)).totalseconds -ge 5) {
        echo "five seconds has passed, removing"
        Get-Job  | Remove-Job -Force
    }
    echo "still running"
    Start-Sleep -Seconds 3
}

PS:我从 Start-Jobs 开始的工作已经处理好了..

PS: My jobs started with Start-Jobs are already taken care of..

推荐答案

对于这个问题，我见过的仅有的两个解决方案是:

The only two solutions I've seen for this problem are:

1. 将查询作为后台作业运行并为其设置计时器，然后停止/删除运行时间过长的作业.

1. Run the queries as background jobs and put a timer on them, then stop/remove the jobs that run too long.

修复您的服务器.
