Version Control debug logging

To enable VCS logging on the server side, switch logging preset to "debug-vcs" in administration web UI and then retrieve logs/teamcity-vcs.log log file.

Most VCS operations occur on the TeamCity server, but if you're using the agent-side checkout, VCS checkout occurs on the build agents.

For the agent and the server, you can change the Log4j configuration manually in <TeamCity home>/conf/teamcity-server-log4j.xml or <BuildAgent home>/conf/teamcity-agent-log4j.xml files to include the following fragment:

<category name="jetbrains.buildServer.VCS" additivity="false">
    <appender-ref ref="ROLL.VCS"/>
    <appender-ref ref="CONSOLE-ERROR"/>
    <priority value="DEBUG"/>
</category>

<category name="jetbrains.buildServer.buildTriggers.vcs" additivity="false">
    <appender-ref ref="ROLL.VCS"/>
    <appender-ref ref="CONSOLE-ERROR"/>
    <priority value="DEBUG"/>
</category>

Please also update the <appender name="ROLL.VCS" node to increase the number of the files to store:

<param name="maxBackupIndex" value="30"/>

Subversion debug logging

To enable SVN logging on the server side, switch the logging preset to "debug-SVN" in the administration web UI and then retrieve the logs/teamcity-vcs.log and logs/teamcity-svn.log files.

An alternative manual approach is also necessary for agent-side logging.

First, please enable the generic VCS debug logging, as described above.

Uncomment the SVN-related parts (the SVN.LOG appender and javasvn.output category) of the Log4j configuration file on the server and on the agent (if the agent-side checkout is used). The log will be saved to the logs/teamcity-svn.log file. Generic VCS log should be also taken from logs/teamcity-vcs.log

ClearCase

Uncomment the Clearcase-related lines in the <TeamCity home>/conf/teamcity-server-log4j.xml file.
The log will be saved to logs/teamcity-clearcase.log directory.
