Diagnose Kubernetes Control Plane Performance Issues with AWS DevOps Agent

This article demonstrates how AWS DevOps Agent diagnoses Amazon EKS API server performance degradation caused by misbehaving controllers flooding the API server with excessive requests.

• AWS DevOps Agent autonomously investigates incidents and correlates signals across CloudWatch metrics, audit logs, and cluster state
• Identifies API Priority and Fairness (APF) seat exhaustion and 429 throttling patterns in EKS clusters
• Simulates a misbehaving controller generating 1,600-2,000 requests per second to demonstrate diagnosis capabilities
• Correlates CloudWatch Logs Insights audit data with metrics to pinpoint offending workloads and service accounts
• Completes root cause analysis in approximately 7 minutes, reducing manual investigation time from hours
• Provides actionable remediation recommendations and proactive improvements based on historical incident patterns

AWS DevOps Agent transforms EKS incident response by automatically correlating multi-signal telemetry to identify control plane performance issues in minutes rather than hours, enabling faster remediation and preventive actions.
