Types

type Resolver

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

Resolver represents an object that makes queries against a target ElasticSearch cluster and transforms the results to a Vulcan Metric type.

func NewResolver

func NewResolver(config *ResolverConfig) (*Resolver, error)

NewResolver creates an instance of Resolver.

func (*Resolver) Resolve

func (r *Resolver) Resolve(matches []*storage.Match) ([]*bus.Metric, error)

Resolve implements the storage.Resolver interface.

func (*Resolver) Values

func (r *Resolver) Values(field string) ([]string, error)

Values returns the unique values for a given metric field. This allows vulcan to provide hinting on what metrics exist or what label values a query should use in a filter.
