Log Errors Effectively and Prevent Email Overload
detail.loadingPreview
This n8n workflow intelligently logs all errors while preventing notification fatigue by limiting alerts to one every 5 minutes. It's designed for robust error management in automated systems.
About This Workflow
This workflow provides a sophisticated solution for managing errors within your automated processes. It ensures that every error is meticulously logged to a PostgreSQL database, creating a comprehensive audit trail. Crucially, it implements a smart alert throttling mechanism, preventing your inbox from being flooded during error surges. By counting logged errors within a 5-minute window, it ensures you receive critical notifications without overwhelming your system or your attention. This workflow can be integrated as a primary error handler or as a sub-workflow to enhance existing error management strategies.
Key Features
- Centralized Error Logging: Captures detailed error information (URL, stack trace, message, workflow name, last node) and stores it in PostgreSQL.
- Intelligent Alert Throttling: Prevents excessive email or notification alerts by limiting them to a maximum of one per 5-minute interval.
- Flexible Integration: Can be used as a standalone error handler or called as a sub-workflow within existing automation.
- Development-Friendly Cleanup: Includes optional error cleanup logic for easier development and testing.
- Customizable Data Mapping: Easily configure which error details are logged and how they are structured in your database.
How To Use
- Database Setup: Ensure you have a PostgreSQL database and create the
N8Errtable with the provided DDL. Replacep1gq6ljdsam3x1mwith your actual schema name. - Configure PostgreSQL Credentials: In n8n, set up and select your PostgreSQL credentials.
- Integrate the Error Trigger: Place the
Error Triggernode at the beginning of your error-handling path, or integrate this workflow as a sub-workflow. - Customize Logging: Adjust the
Insert Lognode'scolumnsparameter to map specific error data to yourN8Errtable fields. - Define Alerting Logic (Optional): If you need immediate notifications, add nodes after the
Insert Lognode to check the count from theCount for 5 minutesnode and send alerts only if the count is below your threshold. - Implement Cleanup (Optional): Utilize the provided cleanup logic at the end of the workflow if needed, especially in development environments.
