Lyo.Metrics.Statistics 1.0.1

Lyo.Metrics.Statistics

Statistical analysis extensions for Lyo.Metrics histograms. Provides percentile / quartile / moving-average / anomaly-detection helpers on top of the metrics primitives in Lyo.Metrics.

This package exists so the base Lyo.Metrics package can stay dependency-light: the heavy Lyo.Mathematics + Lyo.Mathematics.Functions (F#) chain only gets pulled in when callers explicitly opt in by referencing Lyo.Metrics.Statistics.

Examples

Usage

using Lyo.Metrics;

var snapshot = metrics.GetSnapshot();
var p95 = snapshot.Histograms.Values
    .First(h => h.Name == "request.latency")
    .Percentile(95d);

// Or via MetricsService directly
var p95 = metrics.GetHistogramPercentile("request.latency", 95d);
