How to filter tags while ingesting data from OPC UA Extractor?

​@Aditya Kotiyal 

​@Thomas Sjølshagen  Any comment on this?

​@Priyanka Perera You guys probably have done it for customers?

Hi ​@Utkarsh Bhakne, 

I believe you can use the extraction.transformations filtering functionality (from the docs) to add an Includes filter, and do something along the lines of:

extraction:
  # Add this transformations section
  transformations:
    - type: Include
      filter:
        # Use 'name' to specify the exact (OPC UA) node names to include
        name:
          - Boiler.Temperature.Sensor1
          - Pump.Pressure.Value

As you can see from the filtering section, there’s support for RegEx’s when specifying filters.

Thanks ​@Thomas Sjølshagen, will try this out!

Hello ​@Thomas Sjølshagen,

I tried this out but I am getting below error:

The config that I am using is:

extraction:
    # Global prefix for externalId in destinations. Should be unique to prevent name conflicts.
    id-prefix: "opcua:"

    status-codes:

        status-codes-to-ingest: All
        ingest-status-codes: true
    data-types:
        allow-string-variables: true

    transformations:
    - type: Include
      filter:
        name:
          - CPF_116_GD_09201_ST_PV
events:
    enabled: true
history:
    enabled: true
