[Dr. CI] Record click usage on Dr. CI links

[huydhn]

Pitch

Some common questions we have for ourselves from time to time are how useful is the information on Dr. CI page and how best to present it to developers. They're hard questions that don't have fixed answers. As we want to continue to invest in Dr. CI as a developer-facing tool rather than an internal tool used only by DevX, we need to actively measure how effective/useful our message in Dr. CI is to developers. The idea here is to record the clickstream of links on Dr. CI message and use that as the measurement. We probably want to record the following information:

• Number of clicks
• Timestamp
• The PR where it come from
• Audience (Dev Infra engineers, core contributors, contributors, developers). I get the description of different groups from https://github.com/pytorch/pytorch/issues/83363
  • This could benefit greatly from @zengk95 login system that he's building

Solution

I think we could setup a redirection on HUD and records these information

@zengk95 also been working on a login system for HUD. If a user is logged in, then that could let us get even more granular on our usage metrics (like learning "Oh, only Dev Infra folks use the HUD")
