In a previous post we showed how TTN gateways can be monitored using Prometheus. However, the presented solution had some limitations. For example it was only possible to monitor a single gateway. Also the code is now available on GitHub.
To support multiple gateways the output format has slightly be changed. The metrics for the different gateways can now be filtered by the label gateway_id.
