Question

我有一个文件，其中包含具有服务器名称及其sqlserver实例名称的记录。我想为每个记录读取配置的作业及其上次运行的状态。

我设置了凭据，然后定义脚本以收集信息，最后调用Invoke-Command。我的问题是，我希望找到收集的信息，我只是得到了属性的名称。

这是我的剧本：

$a = Get-Credential

$scriptBlock={ 
  param($server,$instance) $OFS=","

  import-module sqlps
  SQLSERVER:
  cd SQL\$server\$instance\JobServer\Jobs
  foreach($CurJob in (ls)){
    write-output "$CurJob.DisplayName`n    Last Run: $CurJob.LastRunDate`n    Ultima Last Run Otcome:$CurJob.LastRunOutcome`n    Next Run: $CurJob.NextRunDate"
  }
}

Import-Csv -Header Server, Instance -Delimiter "|" .\servers_with_jobs.txt | %{
  write-output "Inovoking with server: $_.Server/$_.Instance"

  $JobNumber=Invoke-Command -AsJob -ComputerName $_.Server -Credential $a -ScriptBlock $scriptBlock -ArgumentList $_.Server, $_.Instance

  Wait-Job $JobNumber

  $JobResult = Receive-Job $JobNumber
  $JobResult
}

当我跑步时，我得到以下内容：

Inovoking with server: @{Server=server01.company.net; Instance=INST1}.Server/@{Server=server01.company.net; Instance=INST1}.Instance

Id     Name            PSJobTypeName   State         HasMoreData     Location             Command
--     ----            -------------   -----         -----------     --------             -------
148    Job148          RemoteJob       Completed     True            server01.e...  ...
WARNING: The names of some imported commands from the module 'sqlps' include unapproved verbs that might make them less discoverable. To find the commands with
unapproved verbs, run the Import-Module command again with the Verbose parameter. For a list of approved verbs, type Get-Verb.
ReplicationJob1.DisplayName
    Last Run: ReplicationJob1.LastRunDate
    Ultima Last Run Otcome:ReplicationJob1.LastRunOutcome
    Next Run: ReplicationJob1.NextRunDate
ReplicationJob2.DisplayName
    Last Run: ReplicationJob2.LastRunDate
    Ultima Last Run Otcome:ReplicationJob2.LastRunOutcome
    Next Run: ReplicationJob2.NextRunDate

似乎脚本将作业名称解析为ToString方法。即使我尝试打印$ CurJob对象的类型，但它显示类似于运行Get-Member的输出：

PSComputerName            : server01.company.net
RunspaceId                : 547127ac-ae58-4144-b769-507c6cf18b2e

您需要在字符串评估中评估参数调用。我没有对此进行测试，但我认为这个例子可以解决这个问题。

实施例

$a = Get-Credential

$scriptBlock={ 
  param($server,$instance) $OFS=","

  import-module sqlps
  SQLSERVER:
  cd SQL\$server\$instance\JobServer\Jobs
  foreach($CurJob in (ls)){
    write-output "$($CurJob.DisplayName)`n    Last Run: $($CurJob.LastRunDate)`n    Ultima Last Run Otcome:$($CurJob.LastRunOutcome)`n    Next Run: $($CurJob.NextRunDate)"
  }
}

Import-Csv -Header Server, Instance -Delimiter "|" .\servers_with_jobs.txt | %{
  write-output "Inovoking with server: $($_.Server)/$($_.Instance)"

  $JobNumber=Invoke-Command -AsJob -ComputerName $_.Server -Credential $a -ScriptBlock $scriptBlock -ArgumentList $_.Server, $_.Instance

  Wait-Job $JobNumber

  $JobResult = Receive-Job $JobNumber
  $JobResult
}

更好的方式

使用-f格式化字符串，而不是使用字符串评估。

实施例

'Inovoking with server: {0}/{1}' -f $_.Server, $_.Instance

使用Invoke-Command，在脚本中，方法和属性不起作用
