Application logging with Logback

Logging for eccenca DataManager can also be configured with Logback, which, for example, allows a more granular control on file rolling strategies. For further information on configuration options, refer to the Logback’s Configuration manual section and the Spring Boot’s Configure Logback for logging manual section.

Property	Default	Required	Conflicts with	Valid values
logging.configuration	none	no	none	string (file path)

Use this property to specify where the Logback configuration is located.

Configuration example

logging:
  configuration: "${ELDS_HOME}/etc/datamanager/logback.xml"

The following example logback.xml file defines a rolling file strategy where files are rotated on a time base (1 day) with a limit of 7 files, which means that the logging files contain a log history of a maximum of 1 week.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <appender name="TIME_BASED_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>/opt/elds/var/log/datamanager.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <!-- daily rollover, history for 1 week -->
      <fileNamePattern>/opt/elds/var/log/datamanger.%d{yyyy-MM-dd}.log</fileNamePattern>
      <maxHistory>7</maxHistory>
    </rollingPolicy>
    <encoder>
      <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>
  <logger name="com.eccenca" level="INFO">
    <appender-ref ref="TIME_BASED_FILE" />
  </logger>
</configuration>
