检查多台服务器上的服务状态

Question

我需要一个脚本，它可以检查具有凭据的多个服务器的特定服务状态。我面临的主要问题是每台服务器的服务列表不同。例如，在一个服务器中它是 web 服务，而在另一个数据库服务等中。我想在第一列中保留一个带有服务器名称的 csv 文件，在另一列中保留其相关服务。脚本需要对此进行验证并运行。此外，预期的输出是 CSV。到现在为止我做了这么多，卡住了..希望有人可以帮助我。

$CSVData = import-csv ".\Service.csv"
$Servernames = $CSVData.Servername | sort -unique

$Cred = Get-Credential

foreach ($server in $Servernames) {

$Services = $CSVData | Where {$_.Servername -eq $Server} | Select service
foreach ($Service in $Services) {
    write-host $Server
    $Serv = $Service.service
    Get-WMIObject -computer $server -credential $cred -Query "Select * From Win32_Service WHERE Name Like '$Serv'" | select Name, state
}

}

有什么建议吗？还有助于将输出格式化为 csv

Answer 1

$CSVData = import-csv ".\Service.csv"
$Servernames = $CSVData.Servername | sort -unique
$output = @()

$Cred = Get-Credential

foreach ($server in $Servernames) {

$Services = $CSVData | Where {$_.Servername -eq $Server} | Select service
foreach ($Service in $Services) {
    write-host $Server
    $Serv = $Service.service
    #$ServStat = Get-WMIObject -computer $server -credential $cred -Query "Select * From Win32_Service WHERE Name Like '$Serv'" | select displayname, state
    $ServStat = Get-WMIObject -Query "Select * From Win32_Service WHERE Name Like '$Serv'" | select displayname, state
    $Info =New-object -Typename PSObject
    $Info | Add-Member -MemberType NoteProperty -Name "Hostname" -value $Server
    $Info | Add-Member -MemberType NoteProperty -Name "ServiceName" -value $ServStat.DisplayName
    $Info | Add-Member -MemberType NoteProperty -Name "ServiceStatus" -value $ServStat.state
    $Output +=$Info
}
}

$Output | export-csv ".\Result.csv" -notype

这是我找到的解决方案，如果有改进的余地，请提出建议

有多种方法可以做到这一点。

您可以从包含您的服务器名称和服务的 machines.csv 文件开始：

server,service
server1,WinRM
server2,WinRM
...

然后您可以使用Import-CSV 导入此 CSV 文件：

$computers = Import-Csv -Path .\machines.csv

然后在带有Invoke-Command的远程机器上运行Get-Service检查服务状态：

foreach ($computer in $computers) {
    $cred = Get-Credential -Message "Enter username and password for $($computer.Server)"
    Write-host "$($computer.Service) Service checking on $($computer.Server)" -b "green" -foregroundcolor "red"

    $serviceParams = @{
        "ComputerName" = $computer.Server
        "Command" = {Get-Service -Name $using:computer.Service}
        "Credential" = $cred
    }

    $service = Invoke-Command @serviceParams

    Write-Host "$($computer.Service) Service on $($computer.Server) : $($service.Status)" -b "green" -foregroundcolor "red"
}
