I want to monitor all gateways if they are connected. Like if there was an connection in last hour. We have currently around 60 GW active and we will probably have more then 100 at the end. Thereby I want to be informed when a gateway is not working instead that I have to check it by myself. I want to use Node-Red and I am curious if this is possible and if there is already an howto available.
I recommend to look into the Prometheus metrics option that the LoRa Gateway Bridge provides, see also https://prometheus.io/ for more info.
