Identify and resolve application issues
Navigating through application issues can be challenging. FusionReactor’s Event Snapshot feature offers a practical solution, simplifying the process of identifying and resolving application problems.
1. What is the Event Snapshot?
The Event Snapshot is a core functionality of FusionReactor, designed to provide in-depth insight into specific events that occur during application monitoring.
It automatically generates snapshots for critical events like exceptions or thread latency. Each snapshot includes source code, scope variables, stack trace, and logging information when the problem occurs. This detailed capture aids in isolating issues quickly and efficiently. Event Snapshots are especially significant as they bridge the gap between basic error tracking and the full capabilities of an interactive debugger.
When a log error call is made in an application monitored by FusionReactor, the Event Snapshot feature kicks in. It not only tracks the error but also captures the surrounding context, such as stack variables and the exact state of the application, providing a clear picture of the circumstances leading to the error.
2. How it works
Event Snapshots are triggered automatically under specific conditions, such as log error calls, transaction exceptions, or errors caught in ColdFusion error handlers. The native Debug library, part of FusionReactor’s installation, is crucial for this feature as it allows the interrogation of Java local variables on the call stack.
Users interact with Event Snapshots through FusionReactor’s user interface. The UI displays information such as the cause of the snapshot trigger and detailed diagnostic data. It resembles the Interactive Debugger UI, offering an intuitive experience for users.
These snapshots capture variables, and thread stack traces when specific events occur. There’s a cap on the number of unique variables to ensure efficiency, and specific data structures like collections and arrays have limits on the number of items captured to prevent overwhelming the system.
Consider an application throwing an exception. FusionReactor’s Event Snapshot feature detects this and immediately creates a snapshot. This snapshot includes a complete stack trace and local variables at the time of the exception, accessible through a user-friendly dashboard. This enables developers to understand the context of the error and resolve it more effectively.
3. Why they help you
The primary benefit of Event Snapshots is the ability to provide deep-level insights quickly and effectively, enabling faster problem resolution. This feature helps understand what went wrong and why by giving a complete picture of the system state during an issue.
Event Snapshots significantly reduce the time and effort required to diagnose and fix problems. Sharing snapshot files among similar web requests also helps identify recurring issues.
Unlike traditional error tracking tools that offer limited insights, FusionReactor’s Event Snapshots provide a comprehensive view of problems. This detailed approach, with the user-friendly interface and advanced technology, makes FusionReactor’s Event Snapshots a powerful tool for any development and monitoring team.
Automatically identify and resolve application issues
Event Snapshot in FusionReactor is a valuable tool for any development team. It simplifies diagnosing and fixing application issues, making it an essential component of modern application monitoring and troubleshooting.
