Exactly as Borgso said.. I generally use mosquitto which is an opensource broker written in c http://mosquitto.org/download/ there is also http://emqtt.io/ which is written in erlang both brokers support websockets so you could have realtime dashboards so basically you could create a dashboard and have it subscribe to realtime data and with the broker being integrated on the server you could just use a local client https://github.com/eclipse/paho.mqtt.java ( Java Client) http://www.eclipse.org/paho/clients/c/embedded/ ( c++ Client ) to subscribe to the topics locally.. And if another Netxms server where interested in the data it would just need to subscribe to the topic using any of the above clients or simply bridge the two with a broker to broker bridge..
