notes
Triton main, docs/user_guide/metrics.md, read 2026-10-04. On by default: 'By default, these metrics are available at http://localhost:8002/metrics', and the endpoint is pure pull - 'not pushed or published to any remote server'. tritonserver --allow-metrics=false turns the whole thing off. Labels are model and version, and crucially the LATENCY families are per MODEL, per request-update - not per-request observations as in vLLM/SGLang/TGI. reason in {REJECTED, CANCELED, BACKEND, OTHER}. Ensemble failure accounting double-counts and loses the reason: the component model reports REJECTED while the ensemble reports OTHER with count=2 for the same failure.
