Intent

I need it when

Get immediate alerts when critical errors occur in production applications

Errsole sends critical error notifications that include the error message, app name, environment, server name, and a direct link to view the error in the dashboard. This enables rapid response to production incidents.

Store application logs with flexible backend options and log retention control

Errsole supports multiple storage backends (SQLite for development, MySQL, PostgreSQL, MongoDB for production) and allows configuration of log rotation policies. This gives teams control over where logs are stored and how long they are retained.

Achieve high application performance while maintaining comprehensive logging

Errsole benchmarks show Node.js apps using Errsole handle 90,000 more requests per minute than Elasticsearch and 70,000 more than Amazon CloudWatch, demonstrating minimal performance overhead while providing full logging capabilities.

Implement logging with minimal setup overhead and no external infrastructure

Errsole requires only a single module import with no need for dedicated servers, software installations, or complex configurations. The built-in log viewer and storage options eliminate the need for separate logging infrastructure.

Monitor and debug Node.js application errors in development and production

Errsole automatically collects all console logs and provides advanced logging functions with multiple log levels. It includes a built-in web dashboard to view, filter, and search logs, enabling developers to quickly identify and debug application issues without external dependencies.

  • When you need real-time log aggregation across hundreds of microservices in a distributed system
  • When you prefer not to manage your own database infrastructure or log storage
  • When you require advanced machine learning-based anomaly detection and predictive alerting
