Types

type Metrics

type Metrics struct {
	// Operations
	OperationsStarted   metric.Int64Counter
	OperationsCompleted metric.Int64Counter
	OperationDuration   metric.Float64Histogram

	// Concurrency
	OperationsActive metric.Int64UpDownCounter

	// NATS
	NATSReconnect metric.Int64Counter

	// Dependencies
	PostgreSQLUp metric.Int64ObservableGauge
}

Metrics holds all initialized instruments. Constructed once at startup via New() and passed to wherever needed, or accessed via a global if your pattern requires it.

func NewMetrics
