| the log. Statistics reporting can be configured for a single entity (e.g. a queue) or for all entities of a | |
| particular category (e.g. for all queues). The system can be configured dynamically at runtime without the need | |
| for the system to be restarted.</p><p>This feature helps allow the behaviour of the overall system to be understood and can aid real-time problem | |
| diagnosis.</p><p>It can be configured Broker-wide or separately for each virtual host.</p><p>The format of the statistics report is configurable.</p><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="d0e9629"></a>D.1. Statistics Report Period</h2></div></div></div><p>This governs the period with which statistics reports will be written to the log. The period is defined | |
| in seconds. By default the statistics report period is zero, meaning the system is disabled. To enable the | |
| statistics report set the <span class="emphasis"><em>statistics reporting period</em></span> on either the Broker or virtualhost to | |
