mosquitto_exporter

Prometheus exporter for Mosquitto MQTT broker.

This exporter subscribes to topics under the $SYS tree and exposes values as prometheus metrics.

Tested against Mosquitto v2.0.20.

Due to limitations of the client library, this exporter can only connect using MQTTv3 / MQTTv3.1.

    --mqtt.broker=tcp://127.0.0.1:1883 \
