PowerShellを使って、WMI経由でPingをたたく

WMIにはいくつか面白いオブジェクトがあるので使ってみる。

Win32_PingStatus : 指定されたアドレスにPingを飛ばして詳細な結果オブジェクトを返す

試しに www.google.com にPingを投げてみるには、

PS C:\Users\imksoo> $ping_status = Get-WmiObject -Namespace "root\cimv2" -Query "SELECT * FROM Win32_PingStatus WHERE Address='www.google.com'"

PS C:\Users\imksoo> $ping_status | Get-Member

1秒おきにPingを打ち続けるとかであれば、以下の様にFormat-Tableで現在時刻を付与しながら表示してあげると、後々整形しやすいかと。
(ExPingもどきを目指すのであれば、タイムアウト値とかをGet-WmiObjectコマンドレットでPingStatusオブジェクトを作るときに渡しておくとかでしょうか)

PS C:\Users\imksoo> while ( -not (Start-Sleep 1) ) {
>>  $ping_status = Get-WmiObject -Namespace "root\cimv2" -Query "SELECT * FROM Win32_PingStatus WHERE Address='www.googl
e.com'"
>>  $ping_status | Format-Table -AutoSize @{Label="Date";Expression={Get-Date -Format "G"}},Address,ResponseTime,Respons
eTimeToLive,IPV4Address,IPV6Address
>> }
