rocketmq INFO closeChannel: close the connection to remote address[192.168.8.185:30911] result: true

BUG REPORT
version：rocketmq-all-4.7.1-bin-release dledger、rocketmq-console-ng-2.0.0.jar 、java8

broker-n*:

brokerClusterName = RaftCluster
brokerName=RaftNode00
listenPort=30911
namesrvAddr=192.168.8.185:9876;192.168.8.190:9876

dLegerSelfId=n0
sendMessageThreadPoolNums=16
brokerIP1=192.168.8.185

The cluster can be started，After successful startup, why does the console keep printing INFO closeChannel:
close the connection to remote address [192.168.8.190:30931] result: true
close the connection to remote address [192.168.8.185:9876] result: true

I modified the " rocketmq-console-ng-2.0.0.jar Dlogging.level.root=WARN", after startup, "close the connection to remote address [192.168.8.185:9876] result: true" did not keep printing Up. But there is a message in the log "ERROR Exception caught: mqAdminExt get broker stats data TOPIC_PUT_NUMS failed"，How can I solve this? thanks

Can you help to fix this issue? @zhangjidi2016

ok

1、There is a section in MQAdminExtImpl, which will shutdown MqAdminInstance and then close the channel connection after each invocation of RPC interface. The call chain is:
MQAdminInstance.destroyMQAdminInstance()->mqAdminExt.shutdown()->mqClientInstance.shutdown()->mQClientAPIImpl.shutdown()->mQClientAPIImpl.shutdown()->RemotingUtil.closeChannel(channel).
2、The reason for the "ERROR Exception caught: mqAdminExt get broker stats data TOPIC_PUT_NUMS failed" is that the system topic was not filtered out while console dashbord was making statistics. I will submit a PR to slove this problem in rocketmq-externals.
