I have to parse log files with variable multiline entries using logstash (for which it comes with no codecs).



I simple use the multiline codec with a regex for the first line of an entry and what => "previous", negate => true for later lines, which are pretty unstructured.



Then I use the grok filter. The question is how I can get rid of the following redundancy: I already use a regex for the multiline codec and later a very similar one for grok?
