Pentaho Report Designer: How to configure error logging

Configure logging

By default PRD outputs the log to the console and to a file.

The log output file can be found in (Linux):

~/.pentaho/logs/prd.log

To configure the log settings amend the log4j.xml file in the PRD/resources folder. See here for more details.

To get a more detailed logging, change this section

 <root>

    <priority value="INFO"/>

    <appender-ref ref="CONSOLE"/>

    <appender-ref ref="FILE"/>

 </root>

to

 <root>

    <priority value="DEBUG"/>

    <appender-ref ref="CONSOLE"/>

    <appender-ref ref="FILE"/>

 </root>

Here are all possible values listed (see here for more details):

ALL

TRACE

DEBUG

FATAL

ERROR

INFO

OFF

To follow the log simply run (Usually this is not necessary as on Linux you have the terminal window open from which you started PRD, so the log will be display there):

tail -f ~/.pentaho/logs/prd.log

If you want to adjust the location where the log file is stored simple change following section:

<param name="file" value="${user.home}/.pentaho/logs/prd.log"/>
