• Automatic metric registration

API

MetricsProvider

The main interface for metrics functionality:

// Create a new metrics registry
registry := prometheus.NewRegistry()

// Create metrics provider
metricsProvider := metricsfx.NewMetricsProvider(registry)

// Register custom metrics
counter := prometheus.NewCounter(prometheus.CounterOpts{
  Name: "my_counter",
  Help: "Example counter",
})
metricsProvider.GetRegistry().MustRegister(counter)

HTTP Integration

// Add metrics middleware to your HTTP router
router.Use(metricsfx.NewMetricsMiddleware(metricsProvider))

gRPC Integration

// Add metrics interceptor to your gRPC server
grpcServer := grpc.NewServer(
  grpc.UnaryInterceptor(metricsfx.NewMetricsInterceptor(metricsProvider)),
)
