type Metrics struct {
	// contains filtered or unexported fields
}

Metrics records database operation metrics for one Prometheus namespace. Instances are safe for concurrent use.

func New(namespace string) *Metrics

New returns the shared database metric set for namespace. Passing an empty namespace creates metrics without a namespace prefix.

Metric sets are shared by namespace to prevent duplicate collector registration when multiple database replicas use the same namespace.

func (m *Metrics) Observe(replica, operation, status string, durationSeconds float64)

Observe records the duration and increments the count for a database operation.
