Hi, are you certain the nodes have metadata at all? This is absolutely not a guarantee in OPC-UA systems.
Also, I don’t know what made you set the root node to `i=62`, but this will almost certainly not produce the result you want. ns=0;i=62 is the node BaseVariableType. If your server has timeseries, they will not be found under that node.
Hi Einar,
we do have metadata for nodes as we are verifying using UA Expert tool, i=62 is not a Base variable type or root node.
Is it like you are trying to say that under root node we can’t find any timeseries data, correct me if my understanding is wrong.
I’m able to see metadata once metadata targets, meta data mapping is configured.
I think you are either looking at a node with id `i=62` in the wrong namespace, or there is something wrong with the server. According to the OPC-UA standard, `ns=0;i=62` is the BaseVariableType node.
Hi @Devi Iragavarapu Sri Sandhya,
I hope Einar's reply helped you. Let us know if you have any questions.

Thanks Einar for the Reply!!!
I have changed the configurations in yml file and used metadata-targets and meta data mapping and I can see now the meta data along with timeseries.
Previously I was using raw-metadata and raw session in config_example.yml and not able to get the meta data.
@Dilini Fernando May I know even if we use raw-metadata and raw session in config_example.yml file we will be able to get the meta data ?

The raw-metadata config option just says that the metadata should go into a table in CDF RAW.
You can read more about the config parameters here: https://docs.cognite.com/cdf/integration/guides/extraction/opc_ua/opc_ua_configuration/
Hi @Devi Iragavarapu Sri Sandhya,
