+In v1, an extensive set of metrics are exposed via a Prometheus-compatible `/metrics` endpoint using the `vllm:` prefix, for example:
 
 - `vllm:num_requests_running` (Gauge) - Number of requests currently running.
-- `vllm:num_requests_waiting` (Gauge) - Number of requests currently waiting.
 - `vllm:kv_cache_usage_perc` (Gauge) - Fraction of used KV cache blocks (0–1).
 - `vllm:prefix_cache_queries` (Counter) - Number of prefix cache queries.
 - `vllm:prefix_cache_hits` (Counter) - Number of prefix cache hits.
-- `vllm:mm_cache_queries` (Counter) - (For multimodal models) Number of multimodal cache queries.
-- `vllm:mm_cache_hits` (Counter) - (For multimodal models) Number of multimodal cache hits.
-- `vllm:num_preemptions_total` (Counter) - Number of preemptions.
 - `vllm:prompt_tokens_total` (Counter) - Total number of prompt tokens processed.
 - `vllm:generation_tokens_total` (Counter) - Total number of generated tokens.
-- `vllm:iteration_tokens_total` (Histogram) - Histogram of tokens processed in each engine step.
-- `vllm:cache_config_info` (Gauge) - Information about the cache configuration.
 - `vllm:request_success_total` (Counter) - Number of finished requests (by finish reason).
 - `vllm:request_prompt_tokens` (Histogram) - Histogram of input prompt token counts.
 - `vllm:request_generation_tokens` (Histogram) - Histogram of generation token counts.
-- `vllm:request_params_n` (Histogram) - Histogram of request parameter n.
-- `vllm:request_params_max_tokens` - (Histogram) - Histogram of max_tokens parameter in requests.
 - `vllm:time_to_first_token_seconds` (Histogram) - Time to first token (TTFT).
 - `vllm:inter_token_latency_seconds` (Histogram) - Inter-token latency.
 - `vllm:e2e_request_latency_seconds` (Histogram) - End-to-end request latency.
