Monitoring cellular signal strength on Fortiextender.


I was wondering if anybody here had any experience monitoring cellular signal strength on Fortiextender in Solarwinds. I want to be able to graph the signal strength in node details. We have graphs of cisco cellular products, where we made a Universal Device Poller that is polls the CurrentGsmRssi value. But I´m having a very hard time to find something similar for the Fortiextender.

Any help or advice would be greatly appreciated.
