All other sensors like numeric SNMP values show up the tree view below the green badge. How do I make a custom readout to show up there as well. I have a sensor that reurns a firmware release string like "5.2.200" and I'd love to have it there displayed , instead I need to dig into the sensor and look for a messages.

Hi Maciej,

as far as I know, there is no way except the API.

Hello Maciej,

I'm presuming that you're working with the SNMP Custom String Sensor.
The tree overview will only show the "Primary Channels" of a sensor. What you can do is the following:

  1. Configure the extended processing of the sensor, use a regular expression to extract the numerical value (5.2.200).
  2. A new channel called "Extracted Value" will show up on the sensor containing that value (5.2.200). Configure that channel as the primary channel for the sensor. It will then be visible on the tree overview within PRTG.

Fore more details please see:
