  These cards follow the same format as the Core Web Vitals, providing at-a-glance insights into First Contentful Paint and Time to First Byte.

• Other Metric Reports:

  • Cache Hits:
    The cache hit rate for the last 28 days, with a trend indicator.

7.4 📅 History by Day View: Tracking Daily Changes

This view provides a more granular look at your performance metrics, charting the 75th percentile values for each day over the last 28 days. The History by Day View displays following KPIs and charts:

• CWV (LCP + CLS + INP) + FCP and TTFB, each with:

  • Chart showing 75th percentile value calculated for one single day only for last 28 days
  • Distribution of page loads with Good/Needs Improvement/Poor KPIs

    Navigate, Reload, Back/Forward, Back/Forward Cache, Prerender, Navigate Cache and Restore per day

And Filters to change/drill-down reports as configured in data processing section by

• Period
• Page/Layout
• Browser
• Navigation Type

Why this matters:
This view is invaluable for correlating performance changes with specific events. For example, you can use it to see the immediate impact of a new code deployment, a server configuration change, or the start of a high-traffic marketing campaign.

7.5 🔗 Details Views: Deep Dive Analysis

This is the most powerful feature for diagnosing issues. It allows you to select a specific KPI (like LCP) and apply multiple filters to isolate the root cause of a problem. You can filter by:

• Period
• Page/Layout
• Browser
• Navigation Type

💡 Pro Tip:
If your overall LCP score is poor, use the Details View to check if the problem is specific to a certain browser (e.g., Safari), a particular page layout (e.g., the checkout), or a specific navigation type. This allows you to focus your optimization efforts with precision.

7.6 🕶️ Error Logs View: Proactive Bug Fixing

This view provides a complete report of all captured frontend JavaScript errors.
It includes statistics on error frequency and various filter and drill-down options.

Why this matters:
Instead of waiting for customers to report a problem, you can proactively identify and fix bugs. Clicking on an error reveals the full stack trace and other contextual information, dramatically reducing the time it takes for developers to diagnose and resolve the issue.
