Gentics Mesh uses logback as the main logging facility. Logging can be configured using the config/logback.xml file.
Log levels can be configured per package/class
<logger name="io.vertx" level="INFO"/>
<logger name="com.gentics" level="INFO"/>For all remaining loggers the root level will be used:
<root level="ERROR">Possible values: ERROR, WARN, INFO, TRACE, DEBUG
Logging levels TRACE and DEBUG should only turned on for specific classes. Those levels will cause excessive log output.
By default Gentics Mesh will log errors to errout and other messages to stdout.

</configuration>Syslog logging can be configured using the SyslogAppender. In this example messages will be logged to syslog and console out via the ConsoleAppender.

</configuration>The following example uses the RollingFileAppender to log into the log/mesh.log file. The TimeBasedRollingPolicy will automatically create rotated log and compress old logs.
The INFO lines will be logged to the file and to stdout.
<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">
<conversionRule conversionWord="meshName" converterClass="com.gentics.mesh.log.MeshLogNameConverter"/>
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>log/mesh.log</file>
<target>System.err</target>
<append>true</append>
<encoder>
<pattern>%d [%meshName] %-5level [%file:%line] - %msg%n</pattern>
</encoder>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>log/mesh-%d{yyyy-MM}.log.gz</fileNamePattern>
<maxHistory>12</maxHistory>
</rollingPolicy>
</appender>
<appender name="STDOUT-out" class="ch.qos.logback.core.ConsoleAppender">
<target>System.err</target>
<encoder>
<pattern>%d [%meshName] %-5level [%file:%line] - %msg%n</pattern>
</encoder>
</appender>
<logger name="io.vertx" level="INFO"/>
<logger name="com.gentics" level="INFO"/>
<root level="ERROR">
<appender-ref ref="FILE"/>
<appender-ref ref="STDOUT-out"/>
</root>
</configuration>
The TimeBasedRollingPolicy will control the rotation of logfiles based on the defined fileNamePattern.
