<# .SYNOPSIS Checks the ping latency .DESCRIPTION This PowerShell script measures the ping roundtrip times from the local computer to other computers (10 Internet servers by default). .PARAMETER hosts Specifies the hosts to check, seperated by commata (default is: amazon.com,bing.com,cnn.com,dropbox.com,github.com,google.com,live.com,meta.com,x.com,youtube.com) .EXAMPLE PS> ./check-ping.ps1 ✅ Online with 18ms latency average (13ms...109ms, 0/10 ping loss) .LINK https://github.com/fleschutz/PowerShell .NOTES Author: Markus Fleschutz | License: CC0 #> param([string]$hosts = "bing.com,cnn.com,dropbox.com,github.com,google.com,ibm.com,live.com,meta.com,x.com,youtube.com") try { $hostsArray = $hosts.Split(",") $parallelTasks = $hostsArray | foreach { (New-Object Net.NetworkInformation.Ping).SendPingAsync($_,750) } [int]$min = 9999999 [int]$max = [int]$avg = [int]$success = 0 [int]$total = $hostsArray.Count [Threading.Tasks.Task]::WaitAll($parallelTasks) foreach($ping in $parallelTasks.Result) { if ($ping.Status -ne "Success") { continue } $success++ [int]$latency = $ping.RoundtripTime $avg += $latency if ($latency -lt $min) { $min = $latency } if ($latency -gt $max) { $max = $latency } } [int]$loss = $total - $success if ($success -ne 0) { $avg /= $success Write-Host "✅ Online with $($avg)ms latency average ($($min)ms...$($max)ms, $loss/$total ping loss)" } else { Write-Host "⚠️ Offline ($loss/$total ping loss)" } exit 0 # success } catch { "⚠️ Error in line $($_.InvocationInfo.ScriptLineNumber): $($Error[0])" exit 1 }
