I use the fiware iot-agent opc-ua https://github.com/Engineering-Research-and-Development/iotagent-opcua. How can I get the sorce timestamp of an monitored item from the opc-ua server and add it to the metadata? many thanks!
Please try the last release of the OPC UA Agent! It should satisfy your requirement :-) In the last version, the OPC UA Agent gets OPC UA source and server timestamps (if exist) and sends both as metadata to the Orion Context Broker. You don't need to configure anything to enable that.
