Since the advent of Node.js, application diagnostics have been improved in several stages, from debugging applications to deep performance analysis. Modern diagnostic tools depend on upgrading versions of the V8 engine. As a result, most tools do not support the latest, faster versions of Node.js. The report describes strategies for using tools such as core dump debuggers, flame graphs, GC and Event Loop tracers, which help in finding and fixing performance problems, production errors, and memory leaks at different levels of analysis.
