Log customization

CloudBeaver uses logback.xml to configure server logging. This file controls log level and log message pattern.

Info

For details on viewing logs directly in the CloudBeaver, see Log Viewer.

Default logging configuration

CloudBeaver's default logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{dd-MM-yyyy HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n
            </Pattern>
        </layout>
    </appender>

    <statusListener class="ch.qos.logback.core.status.NopStatusListener"/>
    <logger name="org.jkiss" level="DEBUG"/>
    <logger name="com.dbeaver" level="DEBUG"/>
    <logger name="io.cloudbeaver" level="DEBUG"/>
    <logger name="org.apache.kafka" level="WARN"/>

    <root level="INFO">
        <appender-ref ref="CONSOLE"/>
    </root>

</configuration>

Customize logging level and pattern

Customize CloudBeaver logging by creating a custom logback.xml file:

  1. Create and save your custom logback.xml file on your server.
  2. Mount your custom directory to the container's /opt/cloudbeaver/conf/custom folder.
  3. Restart CloudBeaver to apply your new logging configuration.

Info

For mounting details, see Docker volumes documentation.

Logging level

Set the logging level in the <root> element's level attribute:

  • ERROR: logs errors only.
  • WARN: logs warnings and errors.
  • INFO: standard logs (recommended for everyday use).
  • DEBUG: detailed debugging info.
  • TRACE: maximum verbosity for troubleshooting.

Example:

<root level="WARN">
  <appender-ref ref="CONSOLE"/>
</root>

Info

To enable detailed logging of GraphQL queries, turn it on in Global preferences.

Logging pattern

Define custom log message pattern in the <Pattern> element.

Example (time only):

<Pattern>
    %d{HH:mm:ss} [%t] %-5level - %msg%n
</Pattern>

Customize logging in Preferences

In addition to editing logback.xml, you can configure logging directly in the CloudBeaver preferences. These options let you:

  • save all API requests in the Query Manager database
  • choose how many days to keep logs
  • log GraphQL requests to console

For details, see Preferences - Logger settings.
