> We have had some reports of Agent-Server communication going down because of JSON parsing
error. This is usually a malformed JSON that either the agent sends or receives. We need some
WARN level log to spit out the JSON when such error is encountered.
> The possibility is that the Agent logs the last JSON sent to the server when it encounters
a communication error with the server. And, similarly, it can log the JSON received if response
processing encounters an error. At Controller.py, the heartbeat loop we can log response or
data or both based on when the failure occurs.
