DHCP Sensor



Hello I tried to activate the DHCP Sensor for the domain controller. But the Sensor is not available. There is the information: "To add these sensor types, select a device from the sample!"

What do I have to do in this case?

Hi tim589,

Please note that the DHCP Sensor can only be added to a Probe device. The Sensor works so that it sends a broadcast message to the network and waits for a DHCP server to respond. PRTG only uses the network card of the a Probe Server.

For more detailed information, please follow this link: - https://www.paessler.com/manuals/prtg/dhcp_sensor (below the point "Remarks")

Thank you in advance!

Best Regards, Moritz Heller
