Inverse Ping-Funktion in PRTG

Viele Nutzer von PRTG Network Monitor verwenden das Werkzeug zur Prüfung, ob ein Host mittels Ping erreichbar ist. Was manchen IT-Profis aber fehlt, ist so etwas wie ein invertierter Ping-Sensor – er liefert den Status "OK" zurück, wenn es keine Antwort auf den Ping-Befehl gibt, und "Fehler", sobald sich ein Gerät auf den Ping rückmeldet. Dies lässt sich jedoch mit wenigen Handgriffen und dem Sensor "Ping v2" realisieren.
