如何使用 PsCustomObject 获取计算机名称？

Question

我目前有一个脚本可以 ping 服务器列表并检查每个服务器上的服务运行的状态。我想写信给 log.csv.

我想显示哪些计算机处于离线状态并显示哪些服务处于停止状态。

如何使用 PSCustumObject 获取计算机或机器名称？ CSV 输出只有一行显示离线，但没有在其前面列出计算机名称。

$serviceList = Get-Content C:\services.txt

$results = Get-Content C:\servers.txt | ForEach-Object {
    if (Test-Connection -ComputerName $_ -BufferSize 16 -Count 1 -EA 0 -Quiet) {
        foreach ($service in $serviceList) {
            if ($s=get-service -computer $_ -name $service -ErrorAction SilentlyContinue)
            {
                $s | select MachineName, ServiceName, Status, StartType
            } else {
                # "$_ - Service '$service' does not exist."
            }
        }
    } else {
        $status = Write-Output "Offline"
    }

    [pscustomobject][ordered]@{
        Machine = $_
        Status = $status
    }
}

$results | Export-CSV C:\log.csv -notypeinformation -Append

Answer 1

当您从 Get-Service 输出结果时，您选择 MachineName:

$s | select MachineName, ServiceName, Status, StartType

然后对于离线计算机，您正在使用 Machine:

构建一个对象

[pscustomobject][ordered]@{
    Machine = $_
    Status = $status
}

您需要将自定义对象更新为 MachineName，以便它与您在上面选择的属性相匹配。

它也需要移动到else{}（替换$status = Write-Output "Offline"）所以它只在计算机离线时调用。

然后您将得到您期望的输出：

MachineName ServiceName    Status StartType
----------- -----------    ------ ---------
localhost   spooler       Running Automatic
localhost   DusmSvc       Running Automatic
localhost   DeviceInstall Stopped    Manual
noname                    Offline

更新代码，对不存在的服务进行奖励更新：

$serviceList = Get-Content C:\services.txt

$results = Get-Content C:\servers.txt| ForEach-Object {
    if (Test-Connection -ComputerName $_ -BufferSize 16 -Count 1 -EA 0 -Quiet) {
        foreach ($service in $serviceList) {
            if ($s = get-service -computer $_ -name $service -ErrorAction SilentlyContinue) {
                $s | select MachineName, ServiceName, Status, StartType
            }
            else {
                [pscustomobject][ordered]@{
                    MachineName = $_
                    ServiceName = $service
                    Status  = "NotFound"
                } 
            }
        }
    }
    else {
        [pscustomobject][ordered]@{
            MachineName = $_
            Status  = "Offline"
        } 
    }
}

$results | Export-CSV C:\log.csv -notypeinformation -Append
