Ensuring visibility into the errors and logs of a front-end application in production is essential for maintaining stability and improving user experience. Without proper monitoring, debugging errors requires extensive manual testing to recreate scenarios, which is inefficient.

To address this, we propose integrating Sentry for real-time error tracking. Sentry provides detailed insights into application issues, allowing developers to quickly identify, reproduce, and fix problems in production. Additionally, Sentry can be integrated with Splunk enabling centralized monitoring.

How Sentry Works

Sentry is an error-tracking tool designed to capture and report exceptions in real time. It integrates seamlessly with JavaScript applications, providing detailed stack traces, user context, and breadcrumbs leading up to an error. This allows developers to understand the exact conditions that caused an issue.

Key features include:

• Real-time error tracking and alerting
• Detailed stack traces with source maps
• Performance monitoring for frontend applications
• User session replays for debugging
• Integration with external logging and monitoring tools, including Splunk

Implementation Overview

The integration of Sentry into our project will follow these high-level steps:

1. Setting up a Sentry account – Initially using the free plan, with potential upgrades based on project needs.
2. Adding the Sentry SDK to the front-end project – Ensuring proper configuration to capture errors and performance metrics.
3. Configuring Sentry to work with Splunk – Sending logs and alerts to the existing monitoring infrastructure.
4. Testing and validating the setup – Simulating errors to verify tracking and notifications.
5. Creating dashboards for monitoring – Utilizing Splunk and Sentry’s dashboard capabilities for better insights.
