Automated Error Handling with PostgreSQL Logging and Rate-Limited Notifications

Overview

This workflow automates error handling by capturing errors from n8n workflows, logging them into a PostgreSQL database, and sending notifications to stakeholders. It ensures that error alerts are managed efficiently and avoids notification overload through rate-limiting mechanisms.

Key Features

• Error Detection: Utilizes the errorTrigger node to capture workflow failures in real time.
• Database Logging: Inserts detailed error logs into PostgreSQL for tracking and auditing.
• Rate-Limited Notifications: Counts errors within a 5-minute window to prevent excessive alerts, sending principal and fallback email notifications only when thresholds are met.
• Push Notifications: Sends mobile alerts via Pushover for critical issues.
• Maintenance Tools: Includes nodes for log cleanup and workflow execution management.

Benefits

• Centralized Error Tracking: All errors are systematically logged for easy review and compliance.
• Reduced Alert Fatigue: Rate-limiting ensures only actionable notifications are sent.
• Multi-Channel Alerts: Ensures critical issues reach the right people via email and mobile push.
• Time Savings: Automates manual monitoring and reporting, freeing up IT resources.

Use Cases

• Monitoring mission-critical automations.
• Ensuring compliance with error tracking policies.
• Providing timely, actionable alerts to technical teams.

Integrations

• PostgreSQL for persistent logging.
• Email and Pushover for notifications.
