Summary

Adds support for specifying OPC UA node IDs using the standard string format (e.g., ns=0;i=2262 or nsu=http://...;s=Name) as an alternative to specifying namespace, identifier_type, and identifier separately.

  • Users can now configure nodes using the simpler node_id string that matches what OPC UA browsers display
  • The existing configuration style using individual fields (namespace, identifier_type, identifier) continues to work unchanged
  • Both styles can be used in the same configuration file (but not for the same node)

New style (recommended for simplicity):

  [[inputs.opcua.nodes]]                                                                                                                                                                                                           
    name = "ProductUri"                                                                                                                                                                                                            
    id = "ns=0;i=2262"

Existing style (still fully supported):

  [[inputs.opcua.nodes]]                                                                                                                                                                                                           
    name = "ProductUri"                                                                                                                                                                                                            
    namespace = "0"                                                                                                                                                                                                                
    identifier_type = "i"                                                                                                                                                                                                          
    identifier = "2262"

feat(inputs.opcua, inputs.opcua_listener): Add node_id string configu…

…ration option

- Add support for specifying OPC UA node IDs using the standard string format
  (e.g., "ns=0;i=2262" or "nsu=http://...;s=Name") as an alternative to
  specifying namespace, identifier_type, and identifier separately.
- This simplifies configuration and matches the format used in OPC UA browsers.

Example usage:

  {name="ProductUri", node_id="ns=0;i=2262"}

Instead of:

  {name="ProductUri", namespace="0", identifier_type="i", identifier="2262"}
