Start publishing socket events on inproc.
See libzmq docs for zmq_monitor for details.
Note: requires libzmq >= 3.2
Parameters
----------
addr : str
The inproc url used for monitoring. Passing None as
the addr will cause an existing socket monitor to be
deregistered.
events : int [default: zmq.EVENT_ALL]
The zmq event bitmask for which events will be sent to the monitor.
