描述

Is your feature request related to a problem? Please describe.
In the context of an industrialization of the use of Dash entreperise and Dash for all our research dash application we are facing the problme of offering usable metric to our dev teams to maintain these mini websites. The commonly accepted standard in the telemetry community seems to be openTelemetry, as it's well digested by Azure app insight, Grafana, Jaeger etc....

At this stage there is no out of the box solution to easily implement instruments on top of the Dash application (or I didn't find it) and I'm starting to reinvent the wheel.

Describe the solution you'd like

  • A first step would be to add a way to instrument the callback methods so it can report interaction on the dashboards: error, buttons clicked, data used.
  • A second step would be to do the same for pages load when using multipage dash app
  • Finally the most complicated feature for me is to get a glimpse of when people are entering and exiting an app and who they were (if the app is authenticated). obviously the objective is to encapsulate all the previous mentioned spans into a more global one to have an overview of the "user journey".

Describe alternatives you've considered
I am currently reinventing the wheel internally but I think this functionnality will benefit every users of Dash. so I'm making my problem public.
