Configuration for Prometheus

Promethues logo

With Grafana and Prometheus you can log data from the Gataway and make beautiful graphs and nice dashboards.

There are two ways to get the data from EMS-ESP to Prometheus. Either with MQTT or with API calls.

HTTP API

Github user Poelstra [3] made a Prometheus metrics exporter [2] that exposes metrics from EMS-ESP.

MQTT structure

See Proddy’s EMS-ESP Wiki [1] for all the details on MQTT.
