Monitoring Kubernetes in Production

Monitoring Kubernetes in production environments presents unique challenges compared to traditional server or VM monitoring due to the dynamic and complex nature of containerized applications. Kubernetes, which orchestrates service-oriented applications across clusters, introduces complexities such as increased infrastructure layers, microservices architecture, and high-churn environments. Legacy monitoring tools fall short in providing the necessary visibility and granularity, prompting the need for specialized tools that can handle high cardinality metrics and ephemeral container states. Tools like cAdvisor, Kubernetes metrics server, kube-state-metrics, and Prometheus are essential for building a robust Kubernetes monitoring setup. These tools enable monitoring of clusters, nodes, deployments, and applications, providing insights into resource utilization, application performance, and system health. Prometheus, in particular, has become the de facto standard for Kubernetes monitoring, but scaling it can pose challenges. Sysdig Monitor extends Prometheus capabilities, offering enhanced scalability and security, making it suitable for large-scale environments while maintaining compatibility with existing Prometheus workflows.
