Upcoming release — Zylon 1.58These docs are published ahead of release so you can prepare your API integrations. The release image is not yet available. For installations running 1.57, use the 1.57 documentation.
Platform metrics are the operational metrics generated by the inference stack running in your cluster. They include:
  • Triton metrics such as request rate, failures, queue depth, and latency
  • vLLM metrics such as scheduler state, KV cache pressure, and token throughput
  • GPU metrics from the DCGM exporter
  • Node metrics from node_exporter

Before you enable them

Platform metrics require the monitoring stack:

Enable platform metrics

What you get

Triton

Main metric family: nv_* Examples:
  • nv_inference_request_success
  • nv_inference_request_failure
  • nv_inference_pending_request_count

  • nv_inference_compute_infer_duration_us

vLLM

Main metric families:
  • vllm_llms_v1:*
  • vllm_embeddings_v1:*
Examples:
  • vllm_llms_v1:num_requests_running
  • vllm_llms_v1:kv_cache_usage_perc
  • vllm_llms_v1:time_to_first_token_seconds_bucket
