Decompress gzip fields

edit

The decompress_gzip_field processor specifies a field to gzip decompress. The field key contains a from: old-key and a to: new-key pair. from is the origin and to the target name of the field.

To overwrite fields either first rename the target field or use the drop_fields processor to drop the field and then rename the field.

processors:
  - decompress_gzip_field:
      field:
        from: "field1"
        to: "field2"
      ignore_missing: false
      fail_on_error: true

In the example above: - field1 is decoded in field2

The decompress_gzip_field processor has the following configuration settings:

ignore_missing
(Optional) If set to true, no error is logged in case a key which should be base64 decoded is missing. Default is false.
fail_on_error
(Optional) If set to true, in case of an error the base64 decode of fields is stopped and the original event is returned. If set to false, decoding continues also if an error happened during decoding. Default is true.

See Conditions for a list of supported conditions.
