After completing the configuration for cross-AZ traffic optimization, users can monitor their local network traffic and match it with the accessed brokers to identify the actual situation of cross-AZ data transfer.

​
Monitoring Cross-AZ Traffic with Command-Line Tools

  1. Monitor network traffic: On Linux, you can use iftop to view the incoming and outgoing traffic between the local machine and other IPs. The command is as follows: 
    iftop -t -s 60 -L 100 -n
  2. Identify node availability zones: Query the cluster nodes of AutoMQ and the zones to which the nodes belong. The command is as follows: 
    ./bin/kafka-broker-api-versions.sh --bootstrap-server $bootstrap_server | grep id
    By matching the output of these two commands, you can observe whether cross-AZ traffic is being generated.

​
Other Methods

If your application is deployed on AWS, you can also use the Network Flow Monitor feature of CloudWatch to monitor cross-Zone traffic.
