Determining at which point the logging approach becomes “tracing” or vice-versa might still be open to debate. Much of that is due to the fact that the approaches share tools, vocabulary, and techniques, similar to what happens with the whole “unit tests vs integration tests” debate.įor instance, by applying logging levels, it’s possible to reduce or increase the granularity of a given logger. However, the distinction between tracing and logging isn’t always that clear. With tracing, there is much more information involved, and that’s by design. While logs provide a high-level overview of an event, tracing offers a continuous view of an app, following the progression of data in the program. On the other hand, traces can-and should-be noisier than logs. That would make it hard to read, parse, and extract actionable information from log entries. In other words, logging records events that are relevant to the business logic, or the domain of the application.Ī log shouldn’t have too much noise. Logging-particularly application logging-is generally used to record higher-level information. But they’re still different, and the next section will explore those differences. To be fair, there are many similarities between the two techniques. You wouldn’t be the first to make that connection. You might be thinking that this sounds suspiciously like logging. ![]() With detailed tracing information, it should be possible to “go back in time”, reenacting the sequence of actions performed by the application. Such information can be really useful afterward, especially for debugging and fixing issues. In short, tracing is the process of recording what an application did. This information is typically used by programmers for debugging purposes, and additionally, depending on the type and detail of information contained in a trace log, by experienced system administrators or technical-support personnel and by software monitoring tools to diagnose common problems with software. Tracing involves a specialized use of logging to record information about a program’s execution. ![]() Intro to ASP.NET Tracing Defining Software Tracing
