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="d0e12961"></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 | |
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 width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="Java-Broker-Appendix-Operation-Logging.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="apds02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Appendix C.
