why does the exporter detect only one broker in a two master-noslave cluster?

[BigPang-Git]

I have a cluster with 2master-noslave. rocketmq version: 4.8.0(start by docker) exporter version: 4.3.2(start by docker) first broker name: rocketmq-broker-node1 second broker name: rocketmq-broker-node2 When i browse the exporter website,i only find first broker's tps and qps data.I could not find another broker's qps or tps data. but in other types of data ,i could find two brokers data
