Specifies the amount of debugging information written to the ExtraView log file
evdebug -n
This command may be used to increase or decrease the amount of debugging information written to the ExtraView application log file. The default debugging level is 6. Values of n may be in the range of 1 through 12; 1 writes the least amount of information to the log file, and 12 writes the most information. Setting the debugging level higher than 6 may reduce end-user performance, as considerably more information gets written to the log file.
