Why are there five tracing levels in System.Diagnostics.TraceSwitcher?

C# Interview Questions and Answers

188. Why are there five tracing levels in System.Diagnostics.TraceSwitcher?

The tracing dumps can be quite verbose. For applications that are constantly running you run the risk of overloading the machine and the hard drive. Five levels range from None to Verbose, allowing you to fine-tune the tracing activities.
