Types

type AlertByStateCount

type AlertByStateCount struct {
	Inactive int32
	Pending  int32
	Firing   int32
}

type AlertStatus

type AlertStatus struct {
	Groups               []*rules.Group
	AlertStateToRowClass map[rules.AlertState]string
	Counts               AlertByStateCount
}

AlertStatus bundles alerting rules and the mapping of alert states to row classes.
