Research on gathering more metrics to help audit the website under test

[ankur22]

Feature Description

This issue is for research and POC work only.

We currently have a limited number of metrics that can help the user diagnose or improve their website. The most important ones are the web vitals.

Lighthouse has many data points that are gathered, analysed and displayed to the user in the results which help them understand how they can improve their website.

We want to expose more of the metrics and other useful data points that we can then analyse and suggest ways of improving the website under test.

Suggested Solution (optional)

Take a look at lighthouse and see what they gather. It's important to understand how/where the data points are retrieved from. For example, for web vitals we use the GoogleChrome web vital JS libaray to measure the web vital performance which is then stored and emitted as k6 metrics. How does lighthouse gather the data for all the other datapoints? This is likely to be a good start: gathering data.
