Functions

func New

func New(base mb.BaseMetricSet) (mb.MetricSet, error)

New creates a new instance of the MetricSet. New is responsible for unpacking any MetricSet specific configuration options if there are any.

Types

type MetricSet

type MetricSet struct {
	mb.BaseMetricSet
}

MetricSet holds any configuration or state information. It must implement the mb.MetricSet interface. And this is best achieved by embedding mb.BaseMetricSet because it implements all of the required mb.MetricSet interface methods except for Fetch.

func (*MetricSet) Fetch

func (m *MetricSet) Fetch(reporter mb.ReporterV2) error

Fetch fetches metrics from ZooKeeper by making a tcp connection to the command port and sending the "cons" command and parsing the output.
