I recently deployed a java app on my production server. In which I have installed Tomcat version 8.5 and I have been having problems since the log files stderr and stdout grow in size exaggeratedly and therefore I lower the performance of the server or sometimes it is necessary to restart it since it does not respond. I would like to know how to configure these files so that they create only a certain amount with a specific size. I have tried configuring it through log4j it has given me error when integrating this same a tomcat. I have also configured certain parameters (for example: java.util.logging.FileHandler.limit = 1024) for logging in which the size and quantity are assigned but these do not apply to the configuration and therefore I continue to throw the server .

In a production environment, a good practice is to use a process that works with small log files, and that creates a new one if the critical size has gone.

With log4j you can use a RollingFileAppender. See the minimal configuration : 

<appender name="rolling.file.appender" class="org.apache.log4j.RollingFileAppender">
    <param name="maxFileSize" value="50MB" />
    <param name="maxBackupIndex" value="10" />
    <param name="file" value="${catalina.base}/logs/myApplication.log" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%-5p: %c - %m%n" />
    </layout>
</appender>

<!-- Root Logger -->
<root>
    <priority value="INFO" />
    <appender-ref ref="rolling.file.appender" />
</root>

  • I am using property file I have set up exactly the same thing. The detail that still does not make me that functionality only creates the files but does not register the log (stdout, stderr). So I managed to detect that tomcat is still working with JULI and not using log4j as already configured for such use – Gaara Feb 10 '17 at 04:41
