  ## Option to select the metric timestamp to use. Valid options are:

  ## Client trace messages
  ## When set to true, and debug mode enabled in the agent settings, the OPCUA

  ## Node Group
  ## Sets defaults so they aren't required in every node.
  ## Default values can be set for:
  ## * Metric name
  ## * OPC UA namespace
  ## * Identifier
  ## * Default tags

  ## Multiple node groups are allowed

  ## Group Metric name. Overrides the top level name.  If unset, the
  ## top level name is used.
