https://answers.axonivy.com/questions/3944/how-to-change-the-category-name-of-the-log-when-calling-rest-client-by-using-ivy-rest-client<p>When I call any REST clients by using Ivy.rest().client(...), it will have the log with the category name [rest_client] from IVY Core. However, I want to make the log messages written into the specific log files of each services. With the same category name for all REST services like this, I could not find any way to configure in log4jconfig.xml to make it correct.</p> <p>If anyone have ideas to change that category name or change the log4j configuration, please help.</p> <p>Thanks in advance.</p>enThu, 29 Aug 2019 22:24:52 -0400https://answers.axonivy.com/questions/3944/how-to-change-the-category-name-of-the-log-when-calling-rest-client-by-using-ivy-rest-client/3953<p>Thank you for your suggestion. But I have traced Ivy core, and I see: every time Ivy rest create a <strong>WebTarget</strong> instance, it registers a filter to trace log with specific category name <strong>"rest_client"</strong> in <strong>RestCallLoggingAndHistoryFilter</strong> class. It traces all rest request with same one category. With your suggestion, I only could forward log of all requests to one log file. So, my requirement needs to separate the log content for every request, <strong>every request to every log file.</strong> <strong>How could I do that?</strong> I tried with log4j content filter by regular expression, but it is not working well. And I tried another solution: use <strong>java reflection</strong> for changing the <strong>runtimeLogger</strong> property in that filter to separate them to every log file for every request. But I think this solution not good if the variable has been changed the name in the future or this way will make performance slower a little bit. <strong>Do you have any better solution for this requirement?</strong></p>Lieu VoThu, 29 Aug 2019 22:24:52 -0400https://answers.axonivy.com/questions/3944/how-to-change-the-category-name-of-the-log-when-calling-rest-client-by-using-ivy-rest-client/3953https://answers.axonivy.com/questions/3944/how-to-change-the-category-name-of-the-log-when-calling-rest-client-by-using-ivy-rest-client/3950<p>I do not see an easy solution for this. As the service name is not part of the logger name. Otherwise you could easily route them into files as shown here: <a href="https://developer.axonivy.com/doc/latest/EngineGuideHtml/monitoring.html#d5e3581">https://developer.axonivy.com/doc/latest/EngineGuideHtml/monitoring.html#d5e3581</a></p> <p>What you can do:</p> <ul> <li>use jerseys rest logging feature: and configure or customize it for your needs &gt; <code>org.glassfish.jersey.logging.LoggingFeature</code>.
