https://answers.axonivy.com/questions/1065/i-would-like-to-modify-a-log-level-in-production-without-having-to-restart-the-server<p>Sometimes we want to change the level of logging of a server in production.</p> <p>I am not sure this is possible without restarting the server, which is often difficult to manage depending of the customer.</p> <p>I know that log4j supports a way to dynamically reload the configuration when a file change has been detected. See <a href="http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/DOMConfigurator.html#configureAndWatch%28java.lang.String,%20long%29">configureAndWatch</a>.</p> <p>Is it supported in Ivy 4.x/5.x? Is there something we can do to enable this feature?</p>enMon, 01 Dec 2014 12:24:08 -0500https://answers.axonivy.com/questions/1065/i-would-like-to-modify-a-log-level-in-production-without-having-to-restart-the-server/1071<p>It is possible to change the log level of a Logger in an ivy project. E.g.</p> <pre><code>Logger.getLogger(...).setLevel(Level.DEBUG); </code></pre> <p>I have once started an ivy project that displays all current loggers in a tree and gives you the possibility to change threir level. I share this project here: <a href="http://www.filedropper.com/logviewer">LogViewer.iar</a></p> <p>You can then deploy that project to the server and use it to change the log level of certain loggers.</p>Reto WeissMon, 01 Dec 2014 12:24:08 -0500https://answers.axonivy.com/questions/1065/i-would-like-to-modify-a-log-level-in-production-without-having-to-restart-the-server/1071https://answers.axonivy.com/questions/1065/i-would-like-to-modify-a-log-level-in-production-without-having-to-restart-the-server/1066<p>ivy uses the API which does not watch for configuration changes: <a href="http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/DOMConfigurator.html#configure%28java.lang.String%29">DOMConfigurator.html#configure(java.lang.String)</a></p> <p>today I see no possability to change this behaviour without modifying the ivy core code in <em>ch.ivyteam.log.Logger</em>. </p>Reguel WermelingerMon, 01 Dec 2014 09:00:25 -0500https://answers.axonivy.com/questions/1065/i-would-like-to-modify-a-log-level-in-production-without-having-to-restart-the-server/1066
