Eclipse MQTT Message Broker not working

CindyS — Wed, 02 Mar 2022 14:32:54 GMT

I am following the MQTT Connector tutorial and I can’t get the MQTT Message Broker to work and when I try to troubleshoot by using the debug logs I only see the TCPInboundTransport. There is no com.esri.geoevent.transport.mqtt.MqttInboundTransport or com.esri.geoevent.transport.mqtt.MqttOutboundTransport.

I am using GeoEvent Server 10.9.1 and I have tried the Eclipse Mosquitto 1.6.2 and the latest version 2.0.14.

I have inbound and outbound MQTT Transports and Connectors, but it doesn't seem like the MQTT Message Broker is working.

Thanks.

Cindy,

A good tool for debugging MQTT interfaces is - http://mqtt-explorer.com/

It does work so you probably have a setting that is not aligning between your GeoEvent and MQTT Server.

I have it working. I changed this tcp://127.0.0.1:1883 to this tcp://localhost:1883 and now it works.

That is a little strange as 127.0.0.1 and localhost should the same endpoint just expressed differently.
