Just a quick follow-up I started running this on a throwaway server at
15.184.138.236. So you can subscribe to events from gerrit. Using the
mosquitto_sub command [1] is a simple way to play with it. For example:

 $ mosquitto_sub --topic 'gerrit/#' -h 15.184.138.236

will subscribe to all events

 $ mosquitto_sub --topic 'gerrit/openstack/nova/#' -h 15.184.138.236

will subscribe to all nova events

 $ mosquitto_sub --topic 'gerrit/+/+/comment-added' -h 15.184.138.236

will subscribe to all comment-added events. You can come up with any whatever
subscriptions you want using the builtin wildcards on the protocol. [2] 

I'll probably keep the server running for a while, so feel free to play around
with it.
