Error Logger

Medicus provides robust support for managing errors during health checks. Whether the error occurs in an automatic background check or during a manual check, you can configure a custom errorLogger function to centralize and customize error handling for your system.

Custom Error Logger

The errorLogger is a configurable function that receives the error and the name of the checker where it occurred. This makes it easy to integrate your logging solution and ensure consistent error tracking.

import { Medicus } from 'medicus';

const medicus = new Medicus({
  // Custom error handling implementation
  errorLogger(error, checkerName) {
    console.log('Health check failed:', checkerName, error);
  }
});

Default Error Logger

If no custom error logger is provided, Medicus uses a default implementation based on console.error. This is straightforward and sufficient for development environments but can be replaced with a more robust solution for production.

import { MedicusErrorLogger } from 'medicus';

export const defaultErrorLogger: MedicusErrorLogger = (
  error,
  checkerName
) => {
  console.error(`Health check failed for ${checkerName}`, error);
};

Integrations

Pino

Medicus supports integration with Pino, a high-performance JSON logger, allowing you to easily use Pino as your error logger.

Custom Integrations

Do you need to integrate another logging tool or a custom solution? Medicus is designed to be flexible, letting you add your own error logger with ease.
