Diagnostics Working Group

The goal of this WG is to ensure Node provides a set of comprehensive, documented, extensible diagnostic protocols, formats, and APIs to enable tool vendors to provide reliable diagnostic tools for Node.

Work is divided into several domains:

Background, reference documentation, samples, and discussion for each domain is contained within its folder.

Work needed includes:

  • Collect, understand, and document existing diagnostic capabilities and entry-points throughout Node, V8, and other components.
  • Collect and document projects and products providing diagnostics for Node with brief description of their technical architecture and sponsoring organizations.
  • Identify opportunities and gaps, then propose and implement solutions.
