While working on the tutorial "How to write my own binding component?" I needed to create a realistic use case to work on. So I decided to use the SNMP protocol because ServiceMix still lacks such a binding.
At the weekend I finished up a first version of a SNMP binding component based on the SNMP4J library. It offers a simple polling endpoint which periodically asks a device for some OIDs and sends the polled values as xml document to a defined target service.
Have a look at the component wiki for servicemix-snmp.
Remember, this is only a first shot. There is still much room for improvements.
