Analyze a Kuberly cluster's VPC traffic grouped by source, destination, and ports using the Platform MCP vpc_flow_logs workflow: the managed enable → CloudWatch Logs Insights query → disable lifecycle, the fixed v5 parse prefix, top-talker/NAT-cost/cross-AZ/REJECT grouping queries, and bytes/packets/ action interpretation. Use for "why is networking expensive", "what are the top talkers", "who talks to whom", or "why can't X reach Y" — capture is temporary and billed, so always disable after.
