以下PowerShell脚本在重新启动后监视服务器列表,并在它可以附加到Get-Service后立即通知服务器。PowerShell脚本的实时表格输出

#start all jobs here 
get-job | stop-job 
get-job | remove-job 

$servers = ("localhost", "127.0.0.1", "badserver") 

function Ping-Service($myservers,[int]$timeout=60, [int]$waitbetweentrys=1){ 
    $myservers| %{ 
    $computername = $_ 
    start-job -scriptblock { 
        param(
       [string]$computername, 
       [int]$maxwait, 
       [int]$waitbetween 
       ) 
       $status = "Fail" 
       $StartTime = Get-Date 
       $duration = 0 
       do 
       { 
       #if successful, break out 
       try {$gs = Get-Service -ComputerName $computername -ErrorAction Stop;$status = "Success";break} catch {start-sleep $waitbetween}        
       $duration = (New-TimeSpan $StartTime $(Get-Date)).Seconds 
       } while ($duration -lt $maxwait) 
       $hash = [ordered]@{"Computername" = $computername; "Type" = "Service";"Status"=$status;"Done"=$(Get-Date);"Duration"=$duration}  
       $hash 
      } -ArgumentList ($computername, $timeout, $waitbetweentrys) 
} 
} 
Ping-Service -myservers $servers -timeout 10 

#loops through jobs and check for completed ones 
do 
    { 
     #process jobs that are done 
     $jobsdone = Get-Job | where State -eq 'Completed' 
     $joboutput = $jobsdone | Receive-Job 

     $joboutput | %{New-Object PSObject -Property $_ } |ft -AutoSize 

     #remove jobs once we get the output 
     $jobsdone | Remove-job 

     #See if there are any jobs left  
     $jobsleft = Get-Job 

     #wait 5 seconds before checking jobs 
     if ($jobsleft -ne $null) {start-sleep 5} 

    } while ($jobsleft -ne $null) #continue loop while there are jobs left 

它运作良好,但输出不格式化我怎么会喜欢它:

Duration Status Computername Done    Type 
-------- ------ ------------ ----    ---- 
     0 Success localhost 5/7/2013 4:09:30 PM Service 



Duration Status Computername Done    Type 
-------- ------ ------------ ----    ---- 
     0 Success 127.0.0.1 5/7/2013 4:09:31 PM Service 



Duration Status Computername Done    Type 
-------- ------ ------------ ----    ---- 
     10 Fail badserver 5/7/2013 4:09:42 PM Service 

我想它看起来就像这样:

Duration Status Computername Done    Type 
-------- ------ ------------ ----    ---- 
     0 Success localhost 5/7/2013 4:09:30 PM Service 
     0 Success 127.0.0.1 5/7/2013 4:09:31 PM Service 
     10 Fail badserver 5/7/2013 4:09:42 PM Service 

但是,关键是要实时显示每个结果。具有讽刺意味的是,脚本顶部的开始输出正是我想要的。

如果您在循环中的每个对象上调用Format-Table,它将单独显示它们。输出orginial对象和PowerShell将做到这一点。顺便说一句,你为什么要一个对象)作业输出),并创建一个包含它的新对象? :S

尝试用

$joboutput 

或者也可以简单更换

$joboutput | %{New-Object PSObject -Property $_ } |ft -AutoSize 

,下降$joboutput。更换

$joboutput = $jobsdone | Receive-Job 
$joboutput | %{New-Object PSObject -Property $_ } |ft -AutoSize 

$jobsdone | Receive-Job

我想加在一起所有的输出为对象,所以我可以将该值传递给另一个脚本。如果我按照你的建议修改输出,它将输出一个带有两列的列表视图。 – user2359792 2013-05-08 14:01:33

我没有看到问题。样本是否不完整(在其他地方是否使用了$ jobsdone)?如果是这样,请使用我答案的第一部分来仅修复可见输出。我删除的唯一东西是不必要的对象创建和'format-table'(BY THE WAY,销毁你刚刚创建的对象)。 – 2013-05-08 16:02:28

只是为了澄清更多。如果将代码保存为脚本并运行它,它将返回对象的ARRAY,您可以将其存储和/或传递给另一个cmdlet/function/script。因此,如果默认视图是列表视图,请运行'myscript.ps1 |“之类的东西format-table -autosize'。只记得不要在代码中使用'format -...'cmdlet,因为它返回一个特殊的formatobject,而不是原始的数据对象本身。 – 2013-05-08 18:02:10
