 +== PowerShell Measure Command Time ==
 +
 +Sometimes it's useful to measure how long a command takes. I create the snippet below to measure the amount of time a Test-NetConnection commando took and used it to replicate a sort of ping utility.
 +
 +<code powershell>
 +$counter = 0
 +while ($true){
 +  $timer = [Diagnostics.Stopwatch]::StartNew()
 +  Test-NetConnection kv-shift-001.privatelink.vaultcore.azure.net -port 443 -InformationLevel Quiet
 +  $timer.Stop()
 +  $elapsed = $timer.elapsed
 +  $counter ++
 +  Write-Host "Counter: $counter; in $elapsed seconds"
 +  Sleep 1
 +}
