Seems like this is unused
> Need a Syslog Parser that fully supports the 5424 Spec
> ------------------------------------------------------
>
> Key: NIFI-5325
> URL: https://issues.apache.org/jira/browse/NIFI-5325
> Project: Apache NiFi
> Issue Type: New Feature
> Reporter: Otto Fowler
> Assignee: Otto Fowler
> Priority: Major
>
> from NIFI-5139
> "The Structured Data as described in
> [https://tools.ietf.org/html/rfc5424#section-6.3] are not read by Nifi.
>
> I suggest the SD to be put in attributes, prefixed by the ID:
> [exampleSDID@32473 iut="3" eventSource="Application" eventID="1011"]
> to become 3 attributes
> * exampleSID@32473-iut = 3
> * exampleSID@32473-eventSource=Application
> * exampleSID@32473-eventID=1011
>
> This could be useful to preprocess RFC5424 message, prioritize or route them."
>
> Nifi should a have a parser to fully support the spec and structured data.
> Since integrating it, and special casing the existing parser would
> simnifically complicate that processor and move it from it's least common
> denominator goal, it should be a new parser
>
