HEC-RTS automatically sets the debug level for the HEC-DSS log file to 3. If needed, you can adjust this setting in the Debug tab by entering a debug level between 1 and 6 in the DSS Debug Level box. Be aware that increasing the debug level may result in very large log files, as it controls the amount of HEC-DSS debug information written to the HEC-RTS log file. The location of the Logging Properties File is also displayed in this tab.

More information about the logging levels can be found in the table below.
