Question

我今晚正在努力重新编写现有的服务器运行状况检查脚本，以将其值存储在哈希表中，并且该部分工作正常。但是，我希望结果转到CSV文件，并且该文件仅填充服务器，我将其标记为需要操作。目前，这些正在生成事件ID 7011，或者Test-Connection未通过ping测试。

以下代码：

$CheckServer = @{}
$Servers = (Get-Content $Dir\Test.txt)
foreach ($Server in $Servers) {
    $CheckServer.EventID7011 = Get-Eventlog -LogName System -ComputerName $Server -Newest 1 |
        Where-Object {$_.EventId -eq 7011} | select Message
    if ($CheckServer.EventID -ne $Null) {
        $CheckServer.Server = "$Server"
        $CheckServer.ActionReq = "Yes"
    }

    $CheckServer.Ping = Test-Connection -ComputerName $Server -Count 1 -Quiet
    if (! $CheckServer.Ping) {
        $CheckServer.Server = "$Server"
        $CheckServer.ActionReq ="Yes"
        $CheckServer.Ping = "Offline"
    } else {
        $CheckServer.Server = "$Server"
        $CheckServer.ActionReq = "No"
        $CheckServer.Ping = "Online"
    }

    New-Object -TypeName PSObject -Property $CheckServer |
        Export-Csv "ScanResults.csv" -NoTypeInformation -Append
}

我最后需要正确的代码，因为脚本可以正常收集/存储哈希表数组$CheckServer中的数据，但是我只想选择那些需要的服务器行动。因此，如果我正在扫描100台服务器，其中2台处于ping失败状态，我只想选择那些并发送到Export-Csv。

如果您只想要在输出中不响应Test-Connection的服务器，那么在服务器列表上使用Where-Object过滤器会简单得多：

Get-Content "$Dir\Test.txt" |
    Where-Object { -not (Test-Connection -Computer $_ -Count 1 -Quiet) } |
    Select-Object @{n='Server';e={$_}}, @{n='ActionReq';e={'Yes'}},
                  @{n='Ping';e={'Offline'}} |
    Export-Csv 'ScanResults.csv' -NoType -Append

您需要先将对象存储到列表中，然后才能过滤和导出它们。请参阅代码中带注释的行：

$CheckServer = @{}
$serverObjects = @() # create a list of server objects
$Servers = (get-content $Dir\Test.txt)
ForEach ($Server in $Servers) {

$CheckServer.EventID7011 = get-eventlog -LogName System -ComputerName
$Server -newest 1 | where-object {$_.eventID -eq 7011} |select message
If ($CheckServer.EventID -ne $Null) {
$CheckServer.Server="$Server"
$CheckServer.ActionReq = "Yes"}

$CheckServer.Ping = Test-Connection -ComputerName $Server -count 1 -quiet
if (! $CheckServer.Ping) {
    $CheckServer.Server="$Server"
    $CheckServer.ActionReq ="Yes"
    $CheckServer.Ping= "Offline"}

Else {
    $CheckServer.Server="$Server"
    $CheckServer.ActionReq ="No"
    $CheckServer.Ping= "Online"}

    # Add the server object to the list
        $serverObjects += New-Object -TypeName PSObject -Property $CheckServer 
    }
}
# now filter it:
$serverObjects | where ActionReq -eq "Yes" | Export-Csv -Path "...."
