sawserver logging configuration - logconfig.xml
The configuration of how Presentation Services (sawserver) does its logging is in the file web/config/logconfig.xml (same directory as instanceconfig.xml).
It’s all nice and XML’d:
Logging Detail
Change the numerical values in the FilterRecord entries to alter the detail level of the logging. Lower means less detail, higher means more.
Be aware that your log files can grow very rapidly if you set the logging too high, and unless you’re troubleshooting then leave them at the defaults.
