Extract Tags

The event-extract-tags processor extracts tags from a value, a value name, a tag name or a tag value using regex named groups.

It is possible to overwrite a tag if its name already exists.

processors:
  # processor name
  sample-processor:
    # processor type
    event-extract-tags:
      # list of regular expressions to be used to extract strings to be added as a tag.
      tag-names:
      # list of regular expressions to be used to extract strings to be added as a tag.
      tags:
      # list of regular expressions to be used to extract strings to be added as a tag.
      value-names:
      # list of regular expressions to be used to extract strings to be added as a tag.
      values:
      # boolean, if true tags are over-written with the added ones if they already exist.
      overwrite:
      # boolean, enable extra logging
