Functions

func AddMetrics

func AddMetrics() map[string]*prometheus.Desc

AddMetrics - Add's all of the metrics to a map of strings, returns the map.

func StartServer

func StartServer(service *rpc.Service, pattern, listenAddress string, blockSampleSize uint64,
	logger *logging.Logger) (*http.Server, error)

Types

type Datum

type Datum struct {
	LatestBlockHeight   float64
	UnconfirmedTxs      float64
	TotalPeers          float64
	InboundPeers        float64
	OutboundPeers       float64
	BlockSampleSize     uint64
	TotalTxs            float64
	TxPerBlockBuckets   map[float64]float64
	TotalTime           float64
	TimePerBlockBuckets map[float64]float64
}

Datum is used to store data from all the relevant endpoints

type Exporter

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

Exporter is used to store Metrics data and embeds the config struct. This is done so that the relevant functions have easy access to the user defined runtime configuration when the Collect method is called.

func (*Exporter) Collect

func (e *Exporter) Collect(ch chan<- prometheus.Metric)

Collect function, called on by Prometheus Client library This function is called when a scrape is peformed on the /metrics page

func (*Exporter) Describe

func (e *Exporter) Describe(ch chan<- *prometheus.Desc)

Describe - loops through the API metrics and passes them to prometheus.Describe
