What problem does it solve?

This Skill helps diagnose and resolve issues within the Buttercup Cyber Reasoning System (CRS) deployed on Kubernetes, addressing common problems like pod crashes, resource exhaustion, and service failures.

Core Features & Use Cases

• Triage and Diagnosis: Quickly assess the health of CRS pods and identify the root cause of failures using kubectl commands.
• Log Analysis: Efficiently parse logs from multiple pods to pinpoint error messages and understand failure sequences.
• Resource Monitoring: Check CPU, memory, and disk usage on pods and nodes to identify performance bottlenecks.
• Redis and Queue Inspection: Diagnose issues with the central Redis instance and monitor the status of various task queues.
• Use Case: When multiple services in the crs namespace are in a CrashLoopBackOff state, use this Skill to systematically check pod events, resource limits, and Redis connectivity to find the underlying cause, such as a disk pressure issue on the node or a stalled Redis instance.
