Although it seems wired, Since the broker.id can be overridden in command line, so the broker.id in config/server.properties might not be the real id. It seems that no official command support the finding broker.id, and Andrew Otto's way is more reasonable. There are also two other ways to find the real broker.id. 1. When the broker was being started, the real broker.id will be print on the console or log, and you can check the console or log to find it. 2. Brokers' hostnames(or ip) were kept on zookeeper, so you can find the broker.id according to the broker's hostname(or ip)
