Prometheus metrics
Independent from the chosen MQTT authentication type, the MQTT integration exposes the following Prometheus metrics for monitoring.
integration_mqtt_event_count
The number of gateway events published by the MQTT integration (per event).
integration_mqtt_command_count
The number of commands received by the MQTT integration (per command).
integration_mqtt_connect_count
The number of times the integration connected to the MQTT broker.
integration_mqtt_disconnect_count
The number of times the integration disconnected from the MQTT broker.
integration_mqtt_reconnect_count
The number of times the integration reconnected to the MQTT broker (this also increments the disconnect and connect counters).
