Types

type AlertsRouter

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

AlertsRouter handles alerts generated during alert rule evaluation. Based on rule's orgID and the configuration for that organization, it determines whether an alert needs to be sent to an external Alertmanager and\or internal notifier.Alertmanager

After creating a AlertsRouter, you must call Run to keep the AlertsRouter's state synchronized with the alerting configuration.
