Purpose
Follow-up to #49445. Admission limits reject requests with HTTP 503, but operators cannot tell from metrics which queue cap fired (
max_num_queued_reqsvsmax_num_queued_tokens), and each rejection logged at INFO.This adds
vllm:admission_rejections_total(reasonlabel, noenginelabel). The unit is one rejected frontend admission attempt;n > 1still increments by one. The counter is incremented incheck_admissionthroughStatLoggerManager, matching the sleep-state side door: this event never appears inEngineCoreOutputs.Per-rejection diagnostic messages move from INFO to DEBUG now that the counter exists (requested on #49445 until metrics landed).
Not duplicating:
n > 1admission) remains a separate core change.admission_rejections.Test Plan
Existing admission tests now also assert Prometheus samples (success stays at 0, each reject reason increments once, request-cap-first,
n > 1still +1).vllm:admission_rejections_totalis listed inEXPECTED_METRICS_V1.Test Result
No model evaluation: metrics and logging only; admission decisions are unchanged.
AI assistance was used to draft this change. I reviewed every line and ran the tests above.
