Expand description

Latency / TTFT percentile statistics for LLM spans, grouped by model.

Fields§

§model: Option<String>§count: usize§avg_ms: f64§p50_ms: i64§p95_ms: i64§p99_ms: i64§ttft_count: usize

TTFT is reported only when any span in the group carried a ttft attribute.

§ttft_p50_ms: Option<i64>§ttft_p95_ms: Option<i64>§ttft_p99_ms: Option<i64>§derived_tokens_per_sec_p50: Option<f64>

Derived output token throughput (output_tokens / span_duration_sec). Span duration includes network + queue time, NOT pure generation time. Only set for spans where both output_tokens > 0 and duration > 0.

§derived_tokens_per_sec_p95: Option<f64>§derived_tokens_per_sec_p99: Option<f64>§input_tokens_p50: Option<i64>

Distribution of input token counts (context / prompt size).

§input_tokens_p95: Option<i64>§input_tokens_p99: Option<i64>§output_input_ratio_p50: Option<f64>

Distribution of output/input token ratio (generation verbosity).

§output_input_ratio_p95: Option<f64>§output_input_ratio_p99: Option<f64>
