将停止和启动服务的时间戳打印到 .txt 文件中

Question

I want timestamp when services is stopped/restarted then output to file. The file will become as attached and send to support.

I cannot output to file as my below query seems got error.

$hostname = $env:computername
$smtpServer = 'smtpServer' 
$from = "from" 
$recipients = 'recipients'
$Subject = "Services Restarted Successfully on $hostname $ipv4" 
$body = "This mail confirms that the service on $hostname $ipv4 is now running." 
$ipv4 = (Test-Connection -ComputerName $env:computername -count 1).ipv4address.IPAddressToString
$natip = Invoke-WebRequest ifconfig.me
$timestamp = (Get-Date)
$output = D:\Testing\Restart.txt
$attachment = $output
$service = 'Apache' 

Stop service

Stop-Service -name $service -Verbose 

do { 
    Start-sleep -s 5 | Write-Output "$timestamp Services is stopped" | Out-file $output
    }  
        until ((get-service $service).Status -eq 'Stopped') 

Start service

    start-Service -name $service -Verbose 
do { 
    Start-sleep -s 5 | Write-Output "$timestamp Services is restarted" | Out-file $output
    }  
        until ((get-service $service).Status -eq 'Running') 

Send confirmation that service has restarted successfully

Start-Sleep -s 5 

Send-MailMessage -To $recipients -Subject $Subject -Body $body ((gsv Apache) | out-string) -From $from -SmtpServer $smtpServer -Attachments $attachment

As stated in above comments, change your code to

Stop-Service -name $service -Verbose
do { 
      Start-sleep -s 5 
      Write-Output "$timestamp Services is stopped" | Out-file $output 
  } until ((get-service $service).Status -eq 'Stopped')

Actually your Start-Sleep cmledt calls output is sent to the pipeline ( Start-sleep - s 5 |... ). My guess is that Start-sleep doesn't returns anything, so nothing is send to the pipeline. Based on that Write-Output is not called.

Antoher guess: Assignment to $output fails since your path is not a string, Powershell may interpret the assignment in command mode. Change it to:

  $output = "D:\Testing\Restart.txt"
