What information does a stacktrace provide?

A stack trace provides valuable insight into the part of the code where a request was executed, particularly when an error or exception occurs. It includes a list of the method calls that were active in the program at the time the error happened. Each entry contains the name of the method, the file in which it resides, and the line number, effectively allowing developers to trace back through the execution path of the program.

For example, when an exception is thrown, the stack trace will show the exact sequence of method calls that led to that point, helping developers identify the source of the problem. This clarity is crucial for debugging, as it pinpoints precisely where in the code the issue originated, making it easier to resolve.

The other options do not accurately describe the information contained within a stack trace. The total number of instances executed pertains more to performance metrics, the percentage of successful requests relates to overall system reliability and functionality, and the time taken for each request to process is more aligned with performance monitoring rather than error tracing. Thus, the correct focus on the location of the error within the code highlights the primary role of a stack trace in software development and debugging.
