Hi Felipe, I'm not quite sure if this is possible, but have you considered a portable stream processor that could be run on Edgent? Perhaps it can maintain certain threshold parameters for resource utilization in the device and trigger a call to the backend if those are exceeded.
Thanks and best regards.
