In Python REST APIs, how do I monitor health?

Monitoring the health of Python REST APIs is crucial for ensuring their reliability and performance. Health checks can be implemented using a simple endpoint that returns the status of the application, including checks for database connectivity, external services, and overall uptime.

Example of a Health Check Endpoint

Here is a basic example of how to implement a health check endpoint using Flask, a popular Python web framework:

from flask import Flask, jsonify import requests app = Flask(__name__) @app.route('/health', methods=['GET']) def health_check(): # Example health check logic db_status = check_database() external_service_status = check_external_service() health = { "status": "healthy", "database": db_status, "external_service": external_service_status } return jsonify(health), 200 def check_database(): # Logic to check database connection # Return 'healthy' or 'unhealthy' return "healthy" def check_external_service(): # Logic to ping an external service # Return 'healthy' or 'unhealthy' return "healthy" if __name__ == '__main__': app.run(debug=True)
