domprob 🛰️

Inspired by this blog post, domprob is designed to be a Python package to implement observability domain probes.

📄 Documentation | 🐍 PyPI

Overview

Keep your business logic tidy and abstract the observability code away.

Turn this:

class Order:
    def checkout(self):
        self.logger.log(f"Attempting to checkout order {self.order}")
        try:
            self.checkout_service.checkout_order(self.order)
        except CheckoutError as e:
            self.logger.error(f"Checkout for order {self.order} failed: {e}")
            self.metrics.increment('checkout-failed', ('failed_orders': 1))
            return
        self.logger.log(f"Order checkout completed successfully")
        self.metrics.increment('checkout-successful', ('successful_orders': 1))
