Workload logging for LoRaWAN gateways

I am very interested in fog computing, and I am studying how to combine LoRaWAN with it. The basic idea of fog computing is to do the calculations close to where the data is generated, reducing the pressure on the cloud.

As for LoRaWAN, one way is to add a server down next to the gateway.I’m thinking about the feasibility of this approach, and I have some questions I’d like to ask you guys.

  1. How do you determine the workload of a gateway, CPU? Memory? Number of network requests?

  2. Are there data sets for real-world gateway workloads?

  3. How do I get workload logging of the gateway through simulation?

Thank you for your reply !

I log CPU load on gateways and from experience can advise a Raspi B3+ running an 8 channel gateway has a CPU load around 0.4% and the same with a PiZero the CPU load is just under 10%. There is the occasional blip which is probably related to a Linux operation. The gateways are lightly loaded and I don’t see a CPU load change when packets are received.
