Real user monitoring in Grafana Cloud: Get frontend error tracking, faster root cause analysis, and more

Grafana Cloud has announced the general availability of its Frontend Observability service, which offers real user monitoring (RUM) to enhance the understanding of web application user experiences. This service, available to all Grafana Cloud users including those on the free tier, provides the ability to monitor frontend health, identify and resolve errors, and gain end-to-end visibility into user sessions. The tool measures Web Vitals like Time to First Byte (TTFB) and Largest Contentful Paint (LCP) to provide insights into user interactions, allowing for detailed analysis by dimensions such as device type and session ID. Frontend Observability in Grafana Cloud features automatic error grouping and ranking, facilitating quick troubleshooting by narrowing down the source of errors with JavaScript stack traces. The service integrates with Grafana Cloud Logs for querying and visualizing telemetry data, enabling correlation of frontend performance with business metrics. This holistic approach aids in identifying root causes by linking frontend user sessions with backend request traces, as exemplified by a case study involving a memory leak in a recommendation service.
