Logging and monitoring
Logging microservices can help track errors and failures. Monitoring helps optimize microservices and can signal exceptional occurrences like security attacks.
In Chapter 6, Orchestrating Microservices With Celery and RabbitMQ, we already examined monitoring Celery with the Flower package and RabbitMQ with its built-in features. Here, we focus more on signaling exceptions and reacting to such exceptions.
Depending on your situation and requirements, you can apply the following best practices for logging and monitoring:
- Apply integrated logging
- Implement log levels
