Let's start collecting First Input Delay again in the Navigation Timing Extension and push the data to Prometheus. We had the data for a while and then remove it, but I think it would add value to have it so we can correlate it to the metric we see in Google Search Console.
- Collect the metrics in the Navigation Timing extension and send a new event when we have it
- Create a new schema and make sure we collect the same things as the navtiming schema so we can create the same labels in Prometheus.
- Update navtiming.py and push the metric to Prometheus.
- Create a graph/dashboard in Grafana to keep track of the metric.
