Metrics.Client

Lightweight Prometheus metrics for ASP.NET Core services. Auto-collects HTTP request duration, request count, and active requests with low-cardinality labels.

Quick Start

using Metrics.Client.Extensions;

var builder = WebApplication.CreateBuilder(args);

// Add Prometheus metrics
builder.AddPrometheusMetrics(opts => opts.ServiceName = "MyService");

var app = builder.Build();

// Use Prometheus metrics middleware + /metrics endpoint
app.UsePrometheusMetrics();

await app.RunAsync();

Metrics Collected

Metric Type Labels Description
http_requests_total Counter service, method, endpoint, status_code Total HTTP requests processed
http_request_duration_seconds Histogram service, method, endpoint, status_code Request duration in seconds
http_requests_in_flight Gauge service Currently processing requests

Configuration

Via appsettings.json:

{
  "Metrics": {
    "ServiceName": "MyService",
    "Enabled": true,
    "MetricsPath": "/metrics"
  }
}

Or programmatically:

builder.AddPrometheusMetrics(opts =>
{
    opts.ServiceName = "MyService";
    opts.Enabled = true;
});

Prometheus Scrape Config

scrape_configs:
  - job_name: 'my-service'
    static_configs:
      - targets: ['my-service:8080']
    metrics_path: /metrics

Design Decisions

  • Low cardinality: Uses route templates (not raw paths) for endpoint labels
  • Health/metrics excluded: Health check and metrics endpoints are not tracked to avoid noise
  • Lightweight: No-op overhead when requests hit excluded paths
