ActiveMQ WebConsole的一些参数

     看了这个表格，具体的一列总是看不是很明白。查了一下：

Pending Queue Size - The number of messages in the queue that have yet to be delivered to any client 
Dispatched Counter - The number of message in the queue that have been delivered to a client, but not yet acknowledged 
Enqueue Counter - The number of messages that have been sent to this queue 
Dequeue Counter - the number of messages that have been consumed from this queue

     经过实际测试之后：

    Pending Queue Size：是当前还没有被接收的消息数量。

    Dispatched Queue Size：是当前已经被客户端接收，但还没有ack回执同时commit的消息数量。

    Dispatched Counter：计数器；计算被客户端接收的次数，不管有没有收到加热。

    Enqueue Counter：入队列的消息数

    Dequeue Counter：出队列的消息数（既已被客户端以接收并回执）

    计算公式为：

           Enqueue Counter = Pending Queue Size + Dispatched Queue Size + Dequeue Counter

    以下是从官网截取：

• 
  Enqueue Count - the total number of messages sent to the queue since the last restart
• Dequeue Count - the total number of messages removed from the queue (ack'd by consumer) since last restart
• Inflight Count - the number of messages sent to a consumer session and have not received an ack
• Dispatch Count - the total number of messages sent to consumer sessions (Dequeue + Inflight)
• Expired Count - the number of messages that were not delivered because they were expired
