Logging

Next to the MessageBrokerSettings.yaml file in the config directory there should be another file nlog.config. Message Broker uses common logging library (http://netcommon.sourceforge.net/) in conjunction with NLog (http://nlog-project.org/). In a nutshell: common logging is a factory that hides from the application the actual logging implementation. It is capable to do a simple logging to a console, or so. For more advanced logging setup, it needs a backing library (NLog, log.net, or similar). In case of E4C Message Broker, NLog has been chosen. It is capable to log to file (including file rolling), system event log, console, etc. It is a matter of configuration to replace NLog for any library of a preference. The logging configuration (output file/directory, information being logged, log severity threshold, etc.) is configurable in the file too. In Message Broker configuration file, the logging configuration can be found near the bottom of the file. A sample configuration is presented below. Here NLog is configured to a file. The file is put to c:\tmp\e4c.log directory and is rolled (a new log file is created) every day. Logs produced by Spring.NET package are stored if their level is Info or above. Other logs are created with Trace level, which makes every log sent to a file and console. You may want to edit the log settings and switch off the console logging, change directory, where the log files are created, change logging level, to save some disk space, etc.
