logback has an additional module called logback-access[1], that implements an access log valve for Tomcat. You could then use a logbook appender that writes JSON, eg. the logstash-logback-encoder[2]. Disclaimer: I’ve never used that combination, and don’t know if there are incombatibilities. In theory, it should work.
