I know the sensor is in beta. That said, I noticed that when a device does not report data for a channel in the sensor PRTG records the value as 0 instead of null. This greatly affect number averaging. In the HTTP PUSH DATA ADVANCE sensor, it does handle lack of data in this manner.

Thanks. Dwight.

Dear antinymldyls9e

The historic database of PRTG has no data value of null. If a sensor scan fails, the datapoint is not written at all, implying a null for the according scan. It is not possible to just set individual channels to null. Instead, zero is used.

I understand that this is how it currently works. That's why I titled this as a feature request. The sensor factory sensor handles compiling null data in this matter, but I presume it has significantly different underlying process.

Allow me to be honest: Due to the architecture of the PRTG database, this feature request has no chance of getting implemented in the foreseeable future.

PRTG cannot write a partial sensor result into the data base. The sensor factory has no historic data of its own, the aggregated data is generated on demand.
