Support RFC5424 format #31

Open bdalpe opened 12 months ago

bdalpe commented 12 months ago

Pipelines should support both RFC3164 and RFC5424 formats

jrehm-mmm commented 12 months ago

As an FYI - my current solution is to include a pre-processing pipeline on the source with an anchored parse function that makes OctetFraming optional and stops before the domain if it's included.

_raw.match(/^[\d\s]*\<\d+\>1\s[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}\S*\s([^\.\s]*)/)[1] || host
