>                 Key: AMQ-6518
>                 URL: https://issues.apache.org/jira/browse/AMQ-6518
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.14.2
>         Environment: Linux
>            Reporter: Robert Huffman

> The statistics plugin reports the wrong value for average message size.
> For messages on one of my topic JMX is reporting an average message size of 1242. The statistics plugin is reporting an average message size of 0.
> Digging into this I found that StatisticsPlugin line 123 is the problem. It invokes stats.getMessageSize().getAveragePerSecond() instead of stats.getMessageSize().getAverageSize().
> The result is that the plugin reports 1000 / averageMessageSize instead of averageMessageSize.
> Note I cannot even work around this: it is a double cast as a long, so in my case I cannot even multiple the result by 1000 to come up with an approximation of the actual average message size.
