HeartbeatBroadcaster(period=1.0, endpoint='tcp://*:5555')
Bases: Thread
Sends a heartbeat signal to the endpoint using a PUB-SUB protocol.
The heartbeat message is sent by default every second, but that can be changed
by the period argument (which is in fractional seconds).
Since the broadcaster runs in a thread, it is not a full prove method that the parent process is still running. Therefore, the parent process can set a custom messages on the queue. That custom message will be broadcast at the same time as the next heartbeat, which is probably not the time that the custom message was set. Keep that in mind.
