How can I configure to get DEBUG level log messages of a log category into the Xpert.ivy Server log file.

The log configuration can be changed in the file configuration/log4jconfig.xml.

To configure the log level of a certain category add the following xml to the log4jconfig.xml:

<category name="ch.ivyteam.ivy.security" class="ch.ivyteam.log.Logger">
  <priority value="DEBUG"/>
</category>

Change ch.ivyteam.ivy.security with he name of the category you want to configure.

The log category now logs messages with DEBUG level. But they will not yet be written to the log file because the FileLog appender has normally a threshold set to INFO level. All message with a log level below the threshold are not written to the log file. Therefore you have to change the threshold in the FileLog appender configuration from INFO to DEBUG in the log4jcongig.xml file as follows:

<appender name="FileLog" class="org.apache.log4j.DailyRollingFileAppender">
  <param name="Threshold" value="DEBUG"/>
  <param name="File" value="${user.dir}/logs/ch.ivyteam.ivy.log"/>
  <param name="DatePattern" value="'.'yyyy-MM-dd"/>
  <layout class="org.apache.log4j.IvyLog4jLayout">
    <param name="DateFormat" value="HH:mm:ss.SSS"/>
  </layout>
</appender>
