Calculation rule of total number of message processing: Total number of message processing=Number of message produced + Number of message consumed
Number measuring method of single message body: singe message body size/ 1KB, rounding up.
Calculation sample 1: produce 1 message, message body size is 1.5KB, and message is consumed once, message number is 2+2=4
Calculation sample 2: produce 1 message, message body is 0.5KB, message is consumed twice, message number is 1+2=3
