I've done multiline processing with logstash. It works but it's not necessarily efficient or simple. Depends a lot on the pattern and whether the multiline stack traces you want to extract turns out to be 700 lines long sometimes (yes, speaking from experience). I'd personally recommend to not bother with processing multiline output into a single message. Lots of trouble for no benefits. It's just a stream of lines at the end of the day, it will look the same in tail and kibana.
