PowerShell:Start-Job,Receive-Job:没有返回值

Question

好的,这是我的脚本

$server=@("SERVER1","SERVER2")
$A=@()

foreach($srv in $server){
    start-job -scriptblock {Get-AppHangs $srv}}

while (Get-Job -State "Running"){}

foreach($JB in Get-Job){$A+=Receive-Job $JB}

Remove-Job *

$A|Out-GridView


function Get-AppHangs($srv){
    $A=@()
    $XX=Get-EventLog -ComputerName $srv -LogName "application" | Where-Object {$_.InstanceID -ge 1000 -and $_.InstanceID -lt 1005} | select -First 5

    foreach($x in $XX){
        $time = $_.Time.ToString()
        $obj=New-Object PSObject
        $obj|Add-Member -MemberType "NoteProperty" -Name Server -Value $srv
        $obj|Add-Member -MemberType "NoteProperty" -Name Index -Value $x.Index
        $obj|Add-Member -MemberType "NoteProperty" -Name Time -Value $x.Time -SecondValue System.string
        $obj|Add-Member -MemberType "NoteProperty" -Name EntryType -Value $x.EntryType
        $obj|Add-Member -MemberType "NoteProperty" -Name Source -Value $x.Source
        $obj|Add-Member -MemberType "NoteProperty" -Name InstanceID -Value $x.InstanceID
        $obj|Add-Member -MemberType "NoteProperty" -Name Message -Value $x.Message
        $A+=$obj
    }
    $obj3=New-Object PSObject
    $A+=$obj3
    return $A
}

我的问题是我期待$ A | Out-GridView这一行产生一些有意义的东西.但是gridview甚至没有弹出.

因此,如果我看不起这个剧本,我看不到任何刺眼的东西,但我希望有一双新的眼睛可以复习......

此脚本的目的是能够在事件查看器中找到一组服务器的所有Application Hang ID,并显示在一个漂亮的gridview中...

如果我删除了启动工作和接收工作业务,我能够看到gridview,但我想让这个运行更快,更高效.

heeeeelp;)提前致谢!此外,我无法弄清楚如何将Time属性放入我的自定义对象...如果你有一个提示,那也是惊人的.

更新脚本:

    $server=@("SERVER1","SERVER2")
    $A=@()

    foreach($srv in $server)
    {
        start-job -scriptblock {
                                $A=@()
                                $XX=Get-EventLog -ComputerName $srv -LogName "application" | Where-Object {$_.InstanceID -ge 1000 -and $_.InstanceID -lt 1005} | select -First 5

                                foreach($x in $XX){
                                    $obj=New-Object PSObject
                                    $obj|Add-Member -MemberType "NoteProperty" -Name Server -Value $srv
                                    $obj|Add-Member -MemberType "NoteProperty" -Name Index -Value $x.Index
                                    $obj|Add-Member -MemberType "NoteProperty" -Name EntryType -Value $x.EntryType
                                    $obj|Add-Member -MemberType "NoteProperty" -Name Source -Value $x.Source
                                    $obj|Add-Member -MemberType "NoteProperty" -Name InstanceID -Value $x.InstanceID
                                    $obj|Add-Member -MemberType "NoteProperty" -Name Message -Value $x.Message
                                    $A+=$obj}

                                $obj3=New-Object PSObject
                                $A+=$obj3

                                return $A
                                }
    }
    while (Get-Job -State "Running"){}
    foreach($JB in Get-Job){$A+=Receive-Job $JB}
    Remove-Job *
    $A|Out-GridView

您必须传入服务器参数.作业在单独的进程中运行,$srv如果您不将其作为参数传递,则无法访问您的字符串.在PS3.0中,您可以使用"使用"范围(例如$using:srv),但在PS2.0中,您需要在脚本块param(..)中使用并-Argumentlist发送对象.试试这个:

$server=@("SERVER1","SERVER2")

foreach($srv in $server)
{
    Start-Job -scriptblock {
        param($serv)
        $out=@()
        $XX=Get-EventLog -ComputerName $serv -LogName "application" | Where-Object {$_.InstanceID -ge 1000 -and $_.InstanceID -lt 1005} | select -First 5

        foreach($x in $XX){
            $obj=New-Object PSObject
            $obj|Add-Member -MemberType "NoteProperty" -Name Server -Value $srv
            $obj|Add-Member -MemberType "NoteProperty" -Name Index -Value $x.Index
            $obj|Add-Member -MemberType "NoteProperty" -Name EntryType -Value $x.EntryType
            $obj|Add-Member -MemberType "NoteProperty" -Name Source -Value $x.Source
            $obj|Add-Member -MemberType "NoteProperty" -Name InstanceID -Value $x.InstanceID
            $obj|Add-Member -MemberType "NoteProperty" -Name Message -Value $x.Message
            $out += $obj
        }
        $out
    } -ArgumentList $srv
}

$A = Get-Job | Wait-Job | Receive-Job
$A | Out-GridView

如果要排除runspaceid(start-job添加的属性之一以指定创建对象的位置),请尝试以下操作:

$A | Select-Object -Property * -ExcludeProperty RunspaceID | Out-GridView
