最近，MQ经常有丢包的现象，看各connection/channel/consumer/queue的组成情况，发现差别比较大。

channel与消费者：

[root@iZ23nn1p4mjZ bin]# rabbitmqctl list_channels vhost name consumer_count
Listing channels ...

127.0.0.1:44215 -> 127.0.0.1:5672 (9) 0
127.0.0.1:44297 -> 127.0.0.1:5672 (1) 843
127.0.0.1:44298 -> 127.0.0.1:5672 (1) 843

找到客户端进程：

[root@iZ23nn1p4mjZ bin]# lsof -i:44297
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 7302 root 103u IPv4 783500 0t0 TCP localhost:44297->localhost:amqp (ESTABLISHED)

队列与消费者关系：

[root@iZ23nn1p4mjZ bin]# rabbitmqctl list_queues name consumers | more
