Introducing the Latest Kubernetes Troubleshooting Features

Explore the latest Kubernetes troubleshooting features in this conference talk by Daisuke Kobayashi from Fujitsu. Dive into three cutting-edge developments: Structured Logging, which standardizes log formats for easier querying; Contextual Logging, which improves log management by passing logger instances to callers; and Distributed Tracing, which enables cross-service debugging using OpenTelemetry. Learn how these features enhance log analysis, aggregation, and overall system management through detailed explanations, practical examples, and insights into future log and trace handling techniques. Gain valuable knowledge for Kubernetes system administrators and developers on improving monitoring, management, and troubleshooting in Kubernetes environments.
