Cluster-wide prometheus KongClusterPlugin (kong-metrics.yaml) + chart-native ServiceMonitor (kong-values.yaml) expose kong_http_requests_total/kong_latency_bucket/kong_bandwidth_bytes for every route, LLM and otherwise. Dashboard filters to route=~"llm-.*" for request rate, error rate, p95 upstream latency, and bandwidth. Token-count metrics still need ai-proxy-advanced (Enterprise-only); not attempted.
