To enable debug logging for the Symantec Endpoint Protection Manager API Service (semapisrv), open the following file:
<SEPM>\tomcat\instances\sepm-api\webapps\sepm\WEB-INF\classes\logback.xml
Modify the log value for the following two sections from WARN to DEBUG:
<!-- Package specfic debugging logs -->
<logger name="com.symantec.sepm" additivity="false">
<level value="DEBUG" />
<appender-ref ref="dailyRollingFileAppender"/>
</logger>
<!-- Default log level. Loglevel for catalinaWs.out being redirected to file -->
<root>
<level value="DEBUG" />
<appender-ref ref="rootDailyRollingFileAppender" />
</root>
Once the values are set, save the changes to logback.xml and restart the Endpoint Protection Manager API service.
