Overview of errors at-a-glance across all your monitored frontends to see which OS, user demographic or error type needs immediate attention.Errors are grouped and can be filtered based on type, frontend, OS, etc. Filtered analyses can be with colleagues who have access using the URL.No more guessing as you receive deobfuscated error messages for frameworks like ReactNative. Catch ANRs, identify the root cause, and deploy a fix.Select an error group (occurrence trends, distribution patterns across devices, versions and platforms, or users affected) to prioritize quickly.Extend contextual insights into the user session to understand exactly what led to the error.

Overview

Error Inspector is designed with developers and observability teams in mind to identify, track, and investigate front-end errors in both web and mobile (native or cross-platform) applications. With comprehensive insights into errors affecting users, Error Inspector allows teams to enhance application reliability and performance by automatically prioritizing the most impactful errors across all apps or filter down to the ones you are responsible for. With built-in share functionality, track error workflow, inform cross team members to ensure accountability.

Use cases

  • Understand impact: Assess the impact of errors and their root causes across all your monitored front-end applications.
  • Prioritize errors: Group and prioritize errors with deeper context, sorted by affected users and frequency of occurrence.
  • Identify root cause: Irrespective of whether they are exceptions, ANRs, request errors or CSP violations.
  • Maintain end-to-end context: For all errors tie in the exact user interactions that led up to the error. For request errors examine the trace exception with a single click.
  • Track lifecycle: Manage the lifecycle of errors by creating JIRA tickets directly from Error Inspector.

Get started

As soon as web frontends are automatically detected using OneAgent (or via agentless monitoring), error data is sent to the Dynatrace platform. Users must opt into and allow the new RUM experience either in Classic or Experience Vitals.

Details

Error Inspector is a powerful tool built to help developers and observability teams uncover and investigate frontend errors from both web and mobile applications. Practitioners can visualize error counts and trends over time, thereby breaking down issues by dimensions such as frontend, browser type, operating system, or URL provider. The app supports interactive actions like exporting queries, pinning charts to dashboards, or opening analyses in notebooks. Errors are aggregated and ranked by impact (for example, user count), with filtering capabilities to isolate specific error types or contexts. Individual errors offer rich diagnostic detail, including stack traces (with source map support), session context, and integration options like JIRA ticket creation, and links into Session Details and distributed traces for deeper investigation. By offering both high-level visibility and fine-grained error analysis, Error Inspector empowers teams to proactively resolve frontend issues and drive better user experiences.
