End to end average latency is calculated as below.
- Producer sends first message with current timestamp
- Consumer stores this time stamp as a start time
- Consumer stores current time stamp when last message is received.
- Latency = (Consumers's received last message timestamp - Producer's sent first message timestamp)/total messages received
