Question

OPCUA Extractor - Customize the name of the timeseries name

The current naming convention in the OPCUA server node structure naming is not intuitive for user to be able to find the tag in Cognite.
From the example below, we will have 3 timeseries tags with Message and also Data.
It is not intuitive for user to look into the path or externalid to find which it is belongs to.
How do we configure the OPCUA extractor to construct the timeseries name based on certain criteria or to based on the complete path of the node to be the timeseries name (e.g. Root\Temperature1\Message as the name)?

E.g. OPCUA Node structure
Root
|_ Temperature1
   |_ Message
   |_ Data
|_ Temperature2
   |_ Message
   |_ Data
|_ Pressure1 
   |_ Message
   |_ Data

There is no mechanism to dynamically map timeseries names in the OPC-UA extractor. You can write to CDF Raw instead, and do contextualization later using a tool like Transformations.

I don’t believe that we should pushed the timeseries data to the RAW and then transform to timeseries or other as it defeats the purpose.
Cognite should allow the customization of the timeseries name when pushing OPCUA data up to the timeseries.
