Hello, I need to change the channel on my sensor report, right now I only can see the % and I need the total Memory Mb channel, how I can do that?

the lastvalue property is always the one of the primary channel. You can change that channel in the PRTG interface, using the small pin icon.

As alternative, you can query all channels for each sensor:


Of course, "1002" is just an example ID. One can read channels only per single sensor. You can get that ID with the column "objid".
