To get insights into the performance of your application and what specifically it’s spending time on, you need good tracing tools.
Historically, however, it’s been very difficult to implement tracers in many systems and in Node.js due to its async nature and the lack of an official context propagation API in core.
Throw modern deployment architectures into the mix, and you also need to deal with distributed tracing across multiple microservices.
This talk is about how tracers work behind the scenes, which pitfalls exists and the work going on in the Diagnostics Working Group ( focus on node, js, and .net) , in W3C and within other standards organizations to improve the situation.
