POTracing versus Logging and how does log4net fit in?

Body
copied!<p>I am wondering about what the difference between logging and tracing is.</p> <p>Is the difference basically that tracing is more detailed log giving developers a tool to debug applications at runtime?</p> <p>I have been experimenting with log4net and doing logging. Now I am wondering if I should be doing tracing as well and if I could/should use log4net for that purpose. Should I be doing tracing with log4net and is there some trace level for log4net loggers? Should I use a different log level for debug and trace purposes or is it ok to use the same? Can you give a simple example on how I would do logging and tracing for a simple method?</p> <p>Edit: Despite a few helpful answers below I am still unsure how I should be doing tracing versus logging. </p> <p>I have the following method in my Business layer and I want to add logging/tracing to it. I am wondering how to do it efficiently. Is the following method acceptable in terms of logging/tracing? Should the log messages be of type Info instead of Debug? Are the Debug messages I am logging considered trace? How would you change it?</p> <pre> <code> IEnumerable<Car> GetCars() { try { logger.Debug("Getting cars"); IEnumerable<Car> cars = CarAccessor.GetCars().ConvertAll(DataAccessToBusinessConverter); logger.Debug("Got total of " + cars.Count + " cars"); } catch (Exception e) { logger.Error("Error when getting cars", e); throw new Exception("Unexpected error when getting cars"); } } </code> </pre>
