![]() ![]() You may also want to implement message criticality levels, such as informational messages, warning messages, error messages, and so on. Loggers are very common asked low level system design question. You could implement asynchrony and a queue so that when large numbers of messages arrive, the logger can process these messages asynchronously without having to block the current thread. In this video I have implemented a logging framework. There are many ways you could improve this logging framework. If you ever need to log the text message to a different log target, you would simply pass the appropriate log target as a parameter to the Log() method of the LogHelper class. The following enumeration defines the log targets we would use in this simple framework. ![]() Let’s assume that we will log the data to flat files, a database, and the event log. Logging Context log4net can be used to collect logging context data in a way that is transparent to the developer at the point of logging. In this article we’ll see how we can design and develop our own logging framework with ease, and walk through the steps to build a simple logger in C#.įirst off, you will need to understand the log targets-the various places where the data could be logged. To do this, you could take advantage of one of the many popular logging frameworks available, or you could design and develop your own logging framework. You will often want to log events or errors as they occur in your. ![]()
