This document is an introduction to the log4net API, its log4net appender level unique features and design rationale. Log4net is an open source project based on the work of many authors. It allows the developer to control which log statements are output with arbitrary granularity. It is fully configurable at runtime using external configuration files. Almost every large application includes its own logging or tracing API. Inserting log statements into code is a low-tech method for debugging it. It may also be the only way because debuggers are not always available or applicable. This is usually the case for multithreaded applications and distributed applications at large. Once an application has been deployed it may not be possible to utilize development and debugging tools. An administrator can use effective logging systems to diagnose and fix many configuration issues. Experience indicates that logging is an important component of the development cycle. It offers several advantages. It provides precise context about the exe

Log4net Set Log Level
Asked Questions Information What is log4net? log4net is a tool to help the programmer output log statements to log4net set log level programmatically a variety of output targets. In case of problems with an application, it is helpful to enable logging so that the problem can be located. With log4net it is possible to https://logging.apache.org/log4net/release/manual/introduction.html enable logging at runtime without modifying the application binary. The log4net package is designed so that log statements can remain in production code without incurring a high performance cost. It follows that the speed of logging (or rather not logging) is crucial. At the same time, log output can be so voluminous that it quickly becomes overwhelming. One of the distinctive https://logging.apache.org/log4net/release/faq.html features of log4net (and common to all of the log4x libraries) is the notion of hierarchical loggers. Using these loggers it is possible to selectively control which log statements are output at arbitrary granularity. log4net is designed with two distinct goals in mind: speed and flexibility. There is a tight balance between these two requirements. Back to Top Is log4net a reliable logging system? No. log4net is not reliable. It is a best-effort and fail-stop logging system. By fail-stop, we mean that log4net will not throw unexpected exceptions at run-time potentially causing your application to crash. If for any reason, log4net throws an uncaught exception (except for ArgumentException and ArgumentNullException which may be thrown), please send an email to the log4net-user@logging.apache.org mailing list. Uncaught exceptions are handled as serious bugs requiring immediate attention. Moreover, log4net will not revert to System.Console.Out or System.Console.Error when its designated output stream is not opened, is not writable or becomes full. This avoids corrupting an otherwise working program by flooding the user's terminal because logging fails. However, log4net will output a single message to System.Console.Error and System.Diagnostics.Trace in

Levels are instances of the log4net.Core.Level class. The log4net log levels following levels are defined in order of increasing priority: ALL DEBUG INFO WARN ERROR FATAL OFF DEBUG seems to have lowest priority and ERROR is higher. Question If I set Min and Max example DEBUG and ERROR it prints everthing DEBUG, INFO, WARN and ERROR. Without use of min and max filter. If I specify ERROR (Logging level = ERROR) Will it include DEBUG, INFO & WARN
