Most daemons only use one file (per type of log) and append to it so
logrotate's job is easy: just watch one file and act accordingly.

RabbitMQ uses two files (e.g. rabbitmq.log and rabbitmq.log.1) and
both can grow (= could become too large) so logrotate should watch and
rotate both files. This is unusual.
