The Four Sins of Kubernetes Observability

To achieve effective Kubernetes observability, it's crucial to avoid certain pitfalls, such as relying solely on aggregated logs, focusing only on metrics, or concentrating just on application-level data. Aggregated logs may not provide the complete context needed to understand issues, while metrics alone offer limited insight into the overall state of a cluster. Similarly, focusing only on application data without considering cluster-level details can mask the impact of infrastructure changes on applications. Additionally, depending entirely on managed Kubernetes services for observability may lead to inadequate performance management, as these services typically only offer basic alerts for critical disruptions. A comprehensive observability strategy should integrate various data types from across the cluster and include external data like CI/CD pipeline metrics to provide a holistic understanding of the environment.
