You want to know how to debug LiveUpdate running on SEP for Linux 14.3 RU1 or higher.
SEP for Linux 14.3 RU1+
LiveUpdate logging is saved by default to /opt/Symantec/sdcssagent/AMD/sef/Logs/lux.log
Extended lux debug logging can be enabled by the following:
logger.enabled=true
logger.level=debug
logger.sink=file
logger.sink.file.filePath=/var/log/sdcsslog/amdlog/lux.etl
3. Save and close the file
At this point you can either run LiveUpdate manually to generate the log or wait for LiveUpdate to run automatically.
The log is unreadable for end users, only Technical Support has the tools required for further analysis.
You can disable the debug logging by deleting /opt/Symantec/sdcssagent/AMD/sef/config/lux.logging.conf.
