Which monitoring tools and frameworks are essential for Kubernetes?
Effective monitoring is crucial for maintaining the health, performance, and reliability of Kubernetes clusters and their applications. In this section, we’ll cover some essential monitoring tools and frameworks that are widely used in Kubernetes environments. These tools help collect, store, visualize, and analyze metrics, logs, and traces, providing comprehensive observability of your Kubernetes infrastructure.
What is the Metrics Server, and why do we need it?
