Functions

func New

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

New create a new instance of the MetricSet Part of new is also setting up the configuration by processing additional configuration entries if needed.

Types

type Data

type Data struct {
	Nodes []Node `json:"nodes"`
}

type MetricSet

type MetricSet struct {
	mb.BaseMetricSet
	// contains filtered or unexported fields
}

MetricSet type defines all fields of the MetricSet As a minimum it must inherit the mb.BaseMetricSet fields, but can be extended with additional entries. These variables can be used to persist data or configuration between multiple fetch calls.

func (*MetricSet) Fetch

func (m *MetricSet) Fetch() ([]common.MapStr, error)

Fetch methods implements the data gathering and data conversion to the right format It returns the event which is then forward to the output. In case of an error, a descriptive error must be returned.
