Structured logs are awesome and a great idea. For the next few decades while standards come and go and everyone gets it all implemented across the board, yes it sucks to write grok patterns for the flavor of the week, but once you do it a few times, it takes maybe a few hours of work to get some app cluster with moderately logging flowing into ES with all the right types and all the edge cases accounted for. From there, ELK is such a Swiss Army knife that it's worth the trouble, since then it's e.g. trivial to fire PagerDuty alerts off if you hit some exception-level log lines, or post metrics about your logs, or put them on some queue to flow into some big data pipeline thing.
