log4cplus example

Recently in pondering Log4cplus, this is indeed an artifact. It's easy to use, but the script takes some time to understand. OK, no more nonsense, the following is my configuration of the script, I hope to give friends some help: [Plain] View Plain copy log4cplus.rootlogger=trace,stdout,all_msgs,err_msgs,debug_ msgs,specifial_msgs log4cplus.appender.stdout=log4cplus:: consoleappender log4cplus.appender.s

"Propertyconfigurator" to read the configuration from a file, the parameter is the file name. Other parameters are default. The contents of the configuration file are as follows: 1. Select Logger Logger Logger = Logger::getroot (); This is used to choose Rootlogger. The others can also be configured with more Logger,logger Logger = log4cplus::logger::getinstance ("test"); In general, it is not necessary. 2. Log Output Level TRACE The first parameter

You only need to inherit from Appender or Appender subclass and implement the append member method. After log4cplus is init

Log4cplus is excellent in many aspects, but it is uncomfortable to use it in some places. I'm not happy with it until I continue to talk about it.I will mention it a little and continue to introduce the knowledge about threads and sockets. ### Some improvements ### 1. The implementation mechanism of user-defined loglevel is not open enough In article 5, I have introduced how to implement custom loglevel. To achieve better results, I even need to chang

Logging is an effective tool for all software debugging and positioning issues, and having a good journaling system can help developers quickly locate where the problem may be. A good log system can be arbitrarily controlled according to the user's wishes which log can be output, when it can be output. The same is also possible through the configuration file to control the log output level arbitrarily. Log4cplus is an excellent open source log library
