This is not something I actually did, but you should be able to achieve this by adding a log4j appender for RabbitMQ (such as https://github.com/plant42/rabbitmq-log4j-appender), and configuring the relevant loggers and filters to send only the logging events you need to that appender. BTW, if you just want "fetching started/fetching ended" style messages, you can simply add it to the crawl script, no need to touch the Java code.
