Unfortunately there's isn't a monitor for OpenVPN at present. Any UDP protocol monitoring would be application specific since that communication is asynchronous and therefore would have application specific behaviors. Example: When using the SNMP protocol to "GET" (request) an object from an SNMP agent, the PDU-type field is set to "GetRequest" and the monitoring thread would then listen for a response UDP datagram with PDU-type field set to "Response" on the source port it set in the UDP header of the request.
