RUM Performance Overview Dashboards
The web app performance dashboard offers a bird’s-eye view of RUM web applications. It shows:
- Core web vitals:
For all views, three browser performance metrics are highlighted: Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift. Other performance metrics, such as Load Time, are also available.
- XHR and Fetch requests and resources:
For all views, identify bottlenecks when your application loads.
- Long tasks : Events that block the browser’s main thread for more than 50ms.
For more information about the data displayed, see RUM Browser Data Collected.
The mobile app performance dashboard gives an overview of RUM mobile applications. It shows:
- Mobile vitals:
For all screens, four mobile performance metrics are highlighted: slow renders, CPU ticks per seconds, frozen frames, and memory usage. Other performance metrics, such as crash-free sessions, are also available.
- Resources analysis:
For all screens, identify bottlenecks when your application requests content.
- Crashes and errors:
Identify where crashes and errors can surface in your application.
For more information about the data displayed, see our documentation for each platform: iOS RUM, Android RUM, React Native RUM, and Flutter RUM.
Resources
The RUM resources dashboard helps you identify which resources have the heaviest impact on your application. It shows:
- Most requested resources:
Visualize which resources are being loaded the most, and measure their size and load time.
- XHR and Fetch requests:
Requests repartition, method, and error status codes.
- Resource load timings:
Monitor the trends in resource timings (DNS Lookup, Initial Connection, Time To First Byte, Download) collected by the browser SDK.
- 3rd party resources:
Understand which of your 3rd party resources are having the most impact on your application.
