## Problem The new `api-gateway` ServiceMonitor discovers all 3 replicas, but every scrape fails with `context deadline exceeded`: ``` down api-gateway api-gateway-6986b7c889-pmt4b err=Get "http://10.244.0.180:8080/metrics": context deadline down api-gateway api-gateway-6986b7c889-c28dt err=Get "http://10.244.1.1:8080/metrics": context deadline down api-gateway api-gateway-6986b7c889-552gl err=Get "http://10.244.2.61:8080/metrics": context deadline ``` ## Cause `network-policy.yaml` allowed Prometheus ingress with: ```yaml namespaceSelector: matchLabels: name: monitoring ``` Only `ingress-nginx` carries a plain `name:` label in this cluster. Every other namespace has just `kubernetes.io/metadata.name`, so this rule matched **nothing** and silently denied the scrape. (The rule directly above it — `name: ingress-nginx` — works only because that namespace is the documented exception.) ## Fix Select on `kubernetes.io/metadata.name: monitoring`. ## Impact Unblocks gateway metrics: `llm_ttft_seconds`, `llm_itl_seconds`, `llm_tokens_total`, `queue_full_requests_total`, `warmup_requests_delayed_total`, `vllm_prefix_cache_hit_tokens_total`. These are the only per-request LLM latency series that cover the two Ollama models (`ornith:35b`, `qwen2.5:3b-instruct`), which expose no metrics endpoint of their own. --------- Co-authored-by: Admin Bot <[email protected]> Reviewed-on: #62
