type Reporter 

type Reporter interface {

func ReporterFunc(name string, f func() (report.Report, error)) Reporter

type Tagger 

type Tagger interface {
	Name() string
	Tag(r report.Report) (report.Report, error)
}

Tagger tags nodes with value-add node metadata.

func NewTopologyTagger 

func NewTopologyTagger() Tagger

NewTopologyTagger tags each node with the topology that it comes from. It's kind of a proof-of-concept tagger, useful primarily for debugging.

type Ticker

Ticker is something which will be invoked every spyDuration. It's useful for things that should be updated on that interval. For example, cached shared state between Taggers and Reporters.
