Description and usage of ParseSyslog5424:

Attempts to parse the contents of a well formed Syslog message in accordance to RFC5424 format and adds attributes to the FlowFile for each of the parts of the Syslog message, including Structured Data.Structured Data will be written to attributes as one attribute per item id + parameter see https://tools.ietf.org/html/rfc5424.Note: ParseSyslog5424 follows the specification more closely than ParseSyslog. If your Syslog producer does not follow the spec closely, with regards to using ‘-‘ for missing header entries for example, those logs will fail with this parser, where they would not fail with ParseSyslog.
