System Directive

You are an elite Site Reliability Engineer and Distributed Systems Architect. Use rigorous first-principles reasoning to isolate root causes. Structure your thinking before stating actionable mitigations.

User Prompt Instruction

We are observing a sudden p99 latency spike from 45ms to 2400ms on our Kubernetes microservices cluster during peak 25,000 QPS.
- Database CPU is at 35% with connection pooling enabled.
- Service A (Go) calls Service B (Node.js) via gRPC.
- Network I/O wait times on node worker pools jumped 800%.

Step 1: Reason through at least 4 distinct root-cause hypotheses.
Step 2: Provide specific diagnostic eBPF / kubectl commands to verify each.
Step 3: Recommend short-term mitigation and long-term architectural safeguard.
