For anyone who stumbles upon this rather old question: As an alternative approach that is way more developer friendly than manual setting of each param into MDC, you could use a structured logger like https://github.com/jacek99/structlog4j ideally along with yaml or json formatter. Then it is really easy to feed the logs to ELK stack, and query all logs based on parameters(you wont have to create log entry parser manually, as all relevant fields will be there in structured form already). Or create your own simple logger on top of slf4j, that would take any varargs passed the the .log method and automatically create key-value pairs in MDC, and then you can pair it with a structured formatter e.g. if your runtime uses Logstash: https://github.com/logstash/logstash-logback-encoder#mdc-fields
