OpenNMS (www.opennms.org) is an open source infrastructure management platform which gathers events and performance data from a very wide variety of sources. It has been around for over 15 years and is used by many large enterprises to manage their compute and network infrastructures. Relasing the potential of IoT, the OpenNMS project decided to invest in integrating OpenNMS with Cassandra and Elastic Search to provide a very scalable platform for processing data from an IoT environment. In parallel OpenNMS has developed remote Karaf OSGi based pollers called 'minions' which are ideally suited for distributred data gathering from an IoT infrastructure. This talk will discuss the overall architecture and the value which this feature can bring to an IoT solution.
