Inference performance metrics

Specification

These metrics should be collected and reported for monitoring:

• Latency (p50, p95, p99)
• Throughput
• Cache hit rate
• Heuristic filter rate

Fields

total_calls: u64

Total inference calls

ml_calls: u64

ML inference calls (not cached)

heuristic_calls: u64

Heuristic pre-filter calls

cache_hits: u64

Cache hits

heuristic_short_circuits: u64

Heuristic short-circuits (didn’t need ML)

total_inference_time_ms: u64

Total inference time (milliseconds)

ml_errors: u64

ML inference errors

fallback_count: u64

Fallback to heuristic count

Implementations

impl InferenceMetrics

pub fn cache_hit_rate(&self) -> f32

Calculate cache hit rate (0.0 to 1.0)

pub fn heuristic_filter_rate(&self) -> f32

Calculate heuristic filter rate (% of inputs filtered by heuristic)

pub fn avg_inference_time_ms(&self) -> f32

Calculate average inference time (milliseconds)

pub fn ml_error_rate(&self) -> f32

Calculate ML error rate
