Robust Error Logging and Intelligent Alerting
detail.loadingPreview
Proactively manage workflow errors by logging them to a database and intelligently rate-limiting notifications. This ensures you're informed without being overwhelmed by excessive alerts.
About This Workflow
This n8n workflow provides a sophisticated solution for managing errors in your automated processes. It captures all workflow execution errors and stores detailed information, including stack traces and execution context, in a PostgreSQL database. To prevent alert fatigue from sudden error spikes, it incorporates a clever mechanism to limit notifications to a maximum of one every five minutes. This approach ensures you have a comprehensive error log for debugging and analysis while maintaining a manageable alert system. It's designed for seamless integration into your existing error-handling strategies, whether as a primary handler or a sub-workflow.
Key Features
- Comprehensive Error Logging: Captures and stores detailed error information, including execution URL, stack trace, message, and the workflow/node that triggered the error.
- Intelligent Alert Throttling: Prevents notification overload by limiting alerts to one per five minutes, ensuring critical issues are addressed without overwhelming users.
- Database Integration: Leverages PostgreSQL for robust and scalable error log storage.
- Flexible Integration: Can be used as a standalone error handler or as a sub-workflow within existing automation.
- Development-Friendly Cleanup: Includes optional cleanup logic, particularly useful for managing logs in development environments.
How To Use
- Set up Database: Ensure you have a PostgreSQL database and create the
N8Errtable with the provided DDL (or a compatible structure). - Configure Credentials: Set up your PostgreSQL credentials within n8n.
- Integrate Error Trigger: Use the
Error Triggernode (or an equivalent in your existing workflow) to capture errors. - Log Errors: Configure the
Insert Lognode to write error details to your PostgreSQLN8Errtable, mapping fields likeURL,json,Stack,title,Message,LastNode, andcreated_at. - Implement Alert Throttling: Add the
Count for 5 minutesnode to query the database for recent errors. Use this count in a conditional node to decide whether to send an alert (e.g., only send if the count is 1). - Add Notification Logic: Connect a node (e.g., Email, Slack) after the throttling logic to send alerts when deemed necessary.
- Optional Cleanup: For development, consider adding cleanup steps as outlined in the workflow's sticky note.
