PowerShell Mass Test-Connection


I am attempting to put together a simple script that will check the status of a very large list of servers. in this case we’ll call it servers.txt. I know with Test-Connection the minimum amount of time you can specify on the -count switch is 1. my problem with this is if you ended up having 1000 machines in the script you could expect a 1000 second delay in returning the results. My Question: Is there a way to test a very large list of machines against test-connection in a speedy fashion, without waiting for each to fail one at a time?

current code:


Test-Connection has a -AsJob switch which does what you want. To achieve the same thing with that you can try:

Get-Content -path C:\Utilities\servers.txt | ForEach-Object { Test-Connection -ComputerName $_ -Count 1 -AsJob } | Get-Job | Receive-Job -Wait | Select-Object @{Name='ComputerName';Expression={$_.Address}},@{Name='Reachable';Expression={if ($_.StatusCode -eq 0) { $true } else { $false }}} | ft -AutoSize

Hope that helps!
