Best practices for alerting on Kubernetes

The text explores best practices for effective alerting in Kubernetes environments, emphasizing the need for a comprehensive monitoring strategy that evolves with container orchestration systems. It highlights the challenges posed by new infrastructure layers, such as containers and orchestrators, microservices architecture, and the increased scale and aggregation requirements inherent in Kubernetes. The article suggests that alerts should be based on symptoms and be actionable to avoid unnecessary disturbances, and discusses specific alerting strategies for different layers of Kubernetes, including the host or node layer, Kubernetes infrastructure, and services running on Kubernetes. It also addresses the importance of leveraging container metadata for metric aggregation and segmentation to accurately monitor and alert on application performance, recommending tools like Sysdig Monitor and Prometheus for implementing these strategies. The conclusion underscores the necessity of a container-native monitoring and alerting system to maintain a reliable infrastructure, while also promoting further learning resources and tools for Kubernetes monitoring.
