How do I calculate average ping response time in Powershell using Test-Connection?

Question

I am new to PS scripting. I am in need of help with my code. purpose: ping a list of IP's from a .txt file and output the result in csv format. Here is my code thus far.

$Iplist = Get-Content ips.txt
$group = $()
foreach ($ip in $Iplist)
{
   $status = @{ "ServerIP Name" = $ip; "TimeStamp" = (Get-Date -f s) }
   if (Test-Connection $ip -Count 4 -ea 0 | measure-Object -Property ResponseTime -Average)
   {
        $status["Results"] = "Up"
   }
   else
   {
        $status["Results"] = "Down"
   }
   New-Object -TypeName PSObject -Property $status -OutVariable serverStatus
   $group += $serverStatus
}
$group | export-csv c:\ping\results.csv -NoTypeInformation

Test-Connection returns a Win32_PingStatus object.

To see what else is available on this object in PowerShell type:

$ping = Test-Connection www.google.com #or insert favorite url here
$ping | Format-List | Out-String

Test-Connection doesn't just return a bool. You're really close but you have to assign the return value in order to calculate the average on success:

$Iplist = Get-Content ips.txt
$group = @()
foreach ($ip in $Iplist) {
  $status = @{ "ServerIP Name" = $ip; "TimeStamp" = (Get-Date -f s) }
  $pings = Test-Connection $ip -Count 4 -ea 0
  if ($pings) {
    $status["AverageResponseTime"] =
        ($pings | Measure-Object -Property ResponseTime -Average).Average
    $status["Results"] = "Up"
  }
  else {
    $status["Results"] = "Down"
  }

  New-Object -TypeName PSObject -Property $status -OutVariable serverStatus
  $group += $serverStatus
}

$group | Export-Csv c:\ping\results.csv -NoTypeInformation
