I am looking for a way to update the extraction.id-prefix field inside the OPC-UA extractor config file after partially starting data extraction. Basically, I need to be able to store data in CDF raw with External ID prefix set to a particular tag value coming from the OPC server. So I would need to read the timeseries value of that particular tag from the OPC server and set this value as id-prefix in the extractor config file before pushing subsequent data to CDF raw.Since the pre-built OPC-UA extractor works well for our use case, I am looking for ways to use it as is without having to implement a custom extractor. What would be the best way to implement the functionality mentioned above using the OPC-UA extractor?(Attn. @Jatin Sablok )
Attn. @Jatin Sablok We found some issues with the Cognite pre-built OPC-UA extractor’s automatic re-connection to OPC server and to CDF as detailed in the test cases below.OPC-UA server reconnect test: OPC server is online and Cognite OPC-UA extractor is started. Then OPC server is restarted. Cognite extractor loses connection to OPC server, and is unable to re-connect automatically even after OPC server comes back online later. Extractor service has to be manually restarted to re-connect to OPC server.CDF reconnect test: Cognite OPC-UA extractor is started with network connection cable to CDF unplugged. Extractor log shows error messages. And extractor is unable to connect to CDF automatically even after network cable is plugged back in. Extractor service needs to be manually restarted to connect to CDF.Logs from both tests are attached. Could you please review them and let us know if these are known issues?
