Meet Kubernetes History Inspector, a log visualization tool for Kubernetes clusters
- Kubernetes History Inspector (KHI) is an open-source tool developed by Google Cloud to visualize logs in Kubernetes clusters.
- Troubleshooting in Kubernetes involves dealing with complex logs from various components, requiring deep analysis.
- KHI simplifies log collection and analysis by visualizing log data in a chronological timeline.
- It helps track the evolution of each component over time and link the timeline back to raw log data for better understanding.
- KHI, launched as a container image, does not require lengthy setup or agent installation, making it practical for critical situations.
- By using KHI, engineers can efficiently troubleshoot Kubernetes issues, such as performance degradations or configuration errors.
- The tool provides a macroscopic view of the Kubernetes environment through a timeline and offers microscopic details from raw logs and manifests.
- KHI's visualization helps identify issues like readiness probe failures and visualizes interdependencies within Kubernetes clusters.
- While currently optimized for GKE and Kubernetes on Google Cloud, plans are in place to extend KHI's capabilities to open-source Kubernetes setups.
- KHI, aimed at simplifying Kubernetes operations, requires knowledge of Kubernetes concepts and application architecture for effective troubleshooting.
