<# .SYNOPSIS Checks the ping latency .DESCRIPTION This PowerShell script measures the ping roundtrip times from the local computer to 10 Internet servers. .PARAMETER hosts Specifies the hosts to check, seperated by commata (default is: amazon.com,bing.com,cnn.com,dropbox.com,facebook.com,github.com,google.com,live.com,twitter.com,youtube.com) .EXAMPLE PS> ./check-ping ✅ Ping latency is 29ms average (13ms...109ms, 0 loss) .LINK https://github.com/fleschutz/PowerShell .NOTES Author: Markus Fleschutz | License: CC0 #> param([string]$hosts = "amazon.com,bing.com,cnn.com,dropbox.com,facebook.com,github.com,google.com,live.com,twitter.com,youtube.com") try { Write-Host "✅ Ping latency is" -noNewline $hostsArray = $hosts.Split(",") $t = $hostsArray | foreach { (New-Object Net.NetworkInformation.Ping).SendPingAsync($_, 250) } [Threading.Tasks.Task]::WaitAll($t) [int]$min = 9999999 [int]$max = [int]$avg = [int]$successCount = [int]$lossCount = 0 foreach($ping in $t.Result) { if ($ping.Status -eq "Success") { [int]$latency = $ping.RoundtripTime if ($latency -lt $min) { $min = $Latency } if ($latency -gt $max) { $max = $Latency } $avg += $latency $successCount++ } else { $lossCount++ } } $avg /= $successCount Write-Host " $($avg)ms average ($($min)ms...$($max)ms, $lossCount loss)" exit 0 # success } catch { "⚠️ Error in line $($_.InvocationInfo.ScriptLineNumber): $($Error[0])" exit 1 }
