How to set up and validate locally

1. You need to setup the product analytics devkit if you haven't already done so. https://gitlab.com/gitlab-org/analytics-section/product-analytics/devkit
2. Enable the feature flag: echo "Feature.enable(:product_analytics_internal_preview)" | rails c.
3. Visit the dashboard page of any project and validate that it renders: http://localhost:3000/gitlab-org/gitlab-shell/-/product_analytics/dashboards/

This will show an empty dashboard if you have no events in clickhouse. To generate events:

1. You can use a browser extension like tapermonkey + this userscript to generate events.
   • Using the userscript above you need to change the host to your devkit's Jitsu URL and use your Jitsu's client key.
