Analyzing Kubernetes Events with Cluster Sentinel

Cluster Sentinel is a service for collecting and analyzing Kubernetes events. It retrieves data via watch/list, stores history in SQLite, and ensures metric availability.

The tool solves the problem of manually searching for events in the cluster. It identifies rollout errors, operator failures, and configuration issues.

• History and checkpoints storage in SQLite
• Prometheus metrics and alerts
• Grafana dashboard for visualization
• HTTP API and built-in MCP server

Deployment is done via a Helm chart with persistent storage support. It uses read-only RBAC, enhancing security. A demo mode is available for local testing.
