We'll use open source #Grafana to visualise the #IoT Sensor Data stored in #Prometheus

https://grafana.com/oss/grafana/

#Prometheus needs an MQTT Gateway to ingest Sensor Data from #TheThingsNetwork ... We'll use MQTT2Prometheus

https://github.com/hikhvar/mqtt2prometheus

In MQTT2Prometheus Config we specify the MQTT Server Settings for #TheThingsNetwork

https://github.com/lupyuen/prometheus-the-things-network/blob/main/ttn-mqtt.yaml

We'll ingest these Sensor Values from #TheThingsNetwork as #Prometheus Metrics

https://github.com/lupyuen/prometheus-the-things-network/blob/main/ttn-mqtt.yaml#L38-L65

MQTT2Prometheus shall ingest these #Prometheus Metrics from #TheThingsNetwork over MQTT

https://github.com/lupyuen/cbor-the-things-network#mqtt-log

MQTT2Prometheus works with #TheThingsNetwork because we have decoded our Message Payload with a Payload Formatter

https://lupyuen.github.io/articles/payload

Follow these steps to run MQTT2Prometheus and ingest #TheThingsNetwork Sensor Data as #Prometheus Metrics

https://github.com/lupyuen/prometheus-the-things-network#ingest-the-things-network-mqtt-messages-into-prometheus

Run "curl" to check the #Prometheus Metrics ingested by MQTT2Prometheus from #TheThingsNetwork

https://github.com/lupyuen/prometheus-the-things-network#ingest-the-things-network-mqtt-messages-into-prometheus

Now we configure #Prometheus to scrape the metrics from MQTT2Prometheus

https://github.com/lupyuen/prometheus-the-things-network#configure-prometheus

Every 15 seconds #Prometheus will scrape the metrics from MQTT2Prometheus (via HTTP)

https://github.com/lupyuen/prometheus-the-things-network#configure-prometheus

To check the scraped metrics in #Prometheus, browse to localhost:9090 and enter the Metric Name (t)

https://github.com/lupyuen/prometheus-the-things-network#configure-prometheus

We're ready to connect #Prometheus to #Grafana ... And render our metrics!

https://github.com/lupyuen/prometheus-the-things-network#configure-grafana

Head over to #Grafana and add a Data Source for #Prometheus (localhost:9090)

https://github.com/lupyuen/prometheus-the-things-network#configure-grafana

In #Grafana, add a Panel, set the Data Source to #Prometheus and enter the Metric Name (t)

https://github.com/lupyuen/prometheus-the-things-network#configure-grafana

#TheThingsNetwork Sensor Data appears in #Grafana Dashboard ... Thanks to #Prometheus! 🎉

https://github.com/lupyuen/prometheus-the-things-network#configure-grafana

For security, we should connect #Prometheus to #TheThingsNetwork MQTT with TLS Encryption ... Here's how

https://github.com/lupyuen/prometheus-the-things-network#mqtt-with-tls

In case of TLS Problems with #TheThingsNetwork MQTT ... Wireshark is our best friend!

https://github.com/lupyuen/prometheus-the-things-network#mqtt-with-tls

Monitoring our #IoT Devices connected to #TheThingsNetwork ... With #Prometheus and #Grafana ... All shall be explained in this article
