| 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.

| 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 |
| a non-zero value.</p><p>Once the period is defined, the system will respond to the statistic report patterns defined described next.</p></div></div><div class="navfooter"><hr /><table summary="Navigation footer" width="100%"><tr><td align="left" width="40%"><a accesskey="p" href="Java-Broker-Appendix-Operation-Logging.html">Prev</a> </td><td align="center" width="20%"> </td><td align="right" width="40%"> <a accesskey="n" href="apds02.html">Next</a></td></tr><tr><td align="left" valign="top" width="40%">Appendix C. Operational Logging </td><td align="center" width="20%"><a accesskey="h" href="Apache-Qpid-Broker-J-Book.html">Home</a></td><td align="right" valign="top" width="40%"> D.2. Statistic Report Patterns</td></tr></table></div></div> |
