Debug Logging using debugraw and debugmax
The debugraw and debugmax settings in the cray_logging configuration service enable administrators to debug the operation of the logging system itself. Enabling the debugraw setting will put all raw log messages received by rsyslog into a file. Enabling the debugmax setting will put everything rsyslog knows about each log message, including which host sent the message, into a file.
Because they are resource intensive, the debugraw and debugmax settings are typically left disabled (default) and should be enabled only to diagnose an issue with the rsyslog utility.
