I'm wanting to prepend one line onto each future line, each of which should be shipped separately to Logstash. I haven't been able to find anything that looked like this in the documentation.
The "log" that I'm parsing is broken into sections, i.e.:
What I'd like to do is have the server name prepended to each of the following lines, until another matching servername "start" line is found. To be clear, I want each of the other lines to be a separate message into Logstash, but each should contain the server name that preceded the section.
Is carrying forward a variable like this something that multiline can already do, or would this be an opportunity for an enhancement request?
