Create a sensor that monitors the total of Multiple Groups

I've looked at both Business Process and Sensor Factory Sensors. Neither appears to work for what I need.

I have a group of several devices (Access Points) for our Local Probe, and a similar group of devices for one of our Remote Probes.

I want to be able to display the total amount of sensors -and their UP/DOWN value- for these 2 groups (one local, one remote) in ONE object on our PRTG Map. Otherwise I would need to place two separate group objects (one local, one remote) on our Map.

Is there any formula for the Sensor Factory, similar to status(sensorID), but instead being something like status(groupID) ??

I was able to add the two group objects within a "Business Process" sensor, but that only gives me the UP/DOWN value....and not a total count of the devices across the two groups. I would like to find a way to display both.

groups sensor values

Hello,

counting sensors is outside the scope of the factory or business process sensors, but you can use a trick with the factory sensors to at least count down sensors, as their status() function returns the value of 10000 if it is down. Adding those, and multiplying by 0.0001 gives you the number of down sensors.

To compute the number of app sensors, you have to manually provide the value of the total sensors.

In order to actually count sensors per devices, a custom script is necessary using the PRTG API. This however it not trivial to implement. I recommend to first play around with the API calls manually using the web browser URL.
