Here is another configuration file that uses multiple appenders. The logging priority can be changed by the superuser by editing the log4crc file located in the directory /etc/opt/nec/ve/veos. In example 2, all loggers have an assigned level value. For example, if we want to remove all log statements within our program that use the LOG4CXX_[level] family of macros, add a preprocessor definition LOG4CXX_THRESHOLD set to 50001 or greater. Since log4c and log4net are both ports of log4j, may be you can use log4j/log4net documentation. However, it is far more flexible to configure Log4cxx using configuration files.
