Types

type GangliaDataGetter

type GangliaDataGetter struct {
	Dataset gangliaDataset
	// contains filtered or unexported fields
}

GangliaDataGetter provides interfaces to retrieve data from the Ganglia website, parse it and return relevant data objects.

func (*GangliaDataGetter) Get

func (g *GangliaDataGetter) Get() error

Get retrieves raw data from a ganglia service endpoint, parses the raw data, and turns it into a slice of the gangliaResource data objects.

func (*GangliaDataGetter) GetPrint

func (g *GangliaDataGetter) GetPrint() error

GetPrint retrieves ganglia resource data and print the data to the stdout in a tabular format.
