Logging in Deploy

By default, the Deploy server writes informational, warning, and error log messages to standard output and to XL_DEPLOY_SERVER_HOME/log/deployit.log when it is running. In addition, Deploy:

  • Writes an audit trail to the XL_DEPLOY_SERVER_HOME/log/audit.log file
  • Writes an HTTP log to the XL_DEPLOY_SERVER_HOME/log/access.log file
  • Can optionally log scripts in the XL_DEPLOY_SERVER_HOME/log/scripts.log file

The audit log

Deploy writes an audit log for each human-initiated event on the server. As of Deploy version 9.8*, some of the events that are logged in the audit trail are:

  • The system is started or stopped
  • An application is imported
  • A CI is created, updated, moved, or deleted
  • A security role is created, updated, or deleted
  • A task (deployment, undeployment, control task, or discovery) is started, cancelled, or aborted
  • Login, logout, and failed log in attempts by the user

For each event, the following information is recorded:

  • The user making the request
  • The event timestamp
  • The component producing the event
  • An informational message describing the event

For events involving configuration items (CIs), the CI data submitted as part of the event is logged in XML format.

By default, the audit log is stored in XL_DEPLOY_SERVER_HOME/log/audit.log and is rolled over daily.

Configure audit logging

It is possible to change the logging behavior (for example, to write log output to a file or to log output from a specific source). To do so, edit the XL_DEPLOY_SERVER_HOME/conf/logback.xml file. This is a sample logback.xml file:

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoders are assigned the type
             ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
                %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n

    <!-- Create a file appender that writes log messages to a file -->
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>%-4relative [%thread] %-5level %class - %msg%n</pattern>

    <!-- Set logging of classes in com.xebialabs to DEBUG level -->
    <logger name="com.xebialabs" level="debug"/>

    <!-- Set logging of class HttpClient to DEBUG level -->
    <logger name="HttpClient" level="debug"/>

    <!-- Set the logging of all other classes to INFO -->
    <root level="info">
        <!-- Write logging to STDOUT and FILE appenders -->
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE" />


Configure HTTP access logging

You can change the HTTP access logging behavior in the XL_DEPLOY_SERVER_HOME/conf/logback-access.xml file. The format is slightly different from the logback.xml format.

By default, the access log is done in the so-called combined format, but you can fully customize it. The log file is rolled per day on the first log statement in the new day.

This is a sample logback-access.xml file:

  <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

      <pattern>%h %l %u [%t] "%r" %s %b "%i{Referer}" "%i{User-Agent}"</pattern>

  <appender-ref ref="FILE" />

For information about the configuration and possible patterns, refer to:

To disable the HTTP access log, create a logback-access.xml file with an empty configuration element:


Enable the script log

The logback.xml file contains a section that allows you to enable logging of all Deploy scripts to a separate log file called XL_DEPLOY_SERVER_HOME/log/scripts.log. By default, this section is commented out.

Important: The scripts contain base64-encoded passwords. Therefore, if script logging is enabled, anyone with access to the server can read those passwords.

Logging is configured in the XL_DEPLOY_SERVER_HOME/conf/logback.xml file. To enable debug mode, change the following setting:

<root level="debug">

If this results in too much logging, you can tailor logging for specific packages by adding log level definitions for them. For example:

<logger name="com.xebialabs" level="info" />

You must restart the server to activate the new log settings.

See the Logback documentation for more information.

Enable SQL Queries

To enable the SQL queries performed at the DB level, modify the logback.xml with the following logger:

<logger name="org.springframework.jdbc.core" level="trace" />
