PRTG Manual: Sensor Settings
There is a dedicated section for every sensor with details about the available settings.
For more information, see section List of Available Sensor Types.
For sensor settings, multi-edit is also available. This enables you to change properties of many sensors at the same time. For more information, see section Multi-Edit.
To detect unexpected correlations between your network components, PRTG provides a similar sensors analysis.
Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.
