Greptile Overview

Greptile Summary

Updated RUM dashboard configurations to reflect current Web Vitals standards by replacing the deprecated First Input Delay (FID) metric with Interaction to Next Paint (INP), and adding three new important metrics: First Contentful Paint (FCP), Time to First Byte (TTFB), and Page Load Time.

Key Changes:

• Replaced view_first_input_delay field with view_interaction_to_next_paint in both dashboard configurations
• Added three new visualization panels in web_vitals.json for FCP, TTFB, and Page Load Time metrics
• Adjusted panel layouts to accommodate new metrics (changed panel heights from 8 to 6, added second row with y=8)
• Updated panel IDs and layout indices to maintain proper grid positioning

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• This is a straightforward configuration update that modernizes the RUM dashboard by replacing deprecated Web Vitals metrics with current standards. The changes are limited to JSON dashboard configuration files with no code logic modifications. All metric field names follow consistent naming patterns, SQL queries are properly structured, and panel layouts are correctly positioned without overlaps
• No files require special attention
