var InfuraRegistry = metrics.DefaultRegistry

Note, must use metrics.DefaultRegistry from geth, since go-rpc-provider depends on it for rpc metrics by default. When RPC middleware supported at server side, we can use a custom metrics registry.

Functions

func GetOrRegisterCounter 

func GetOrRegisterCounter(nameFormat string, nameArgs ...interface{}) metrics.Counter

func GetOrRegisterGauge 

func GetOrRegisterGauge(nameFormat string, nameArgs ...interface{}) metrics.Gauge

func GetOrRegisterGaugeFloat64 

func GetOrRegisterGaugeFloat64(nameFormat string, nameArgs ...interface{}) metrics.GaugeFloat64

func GetOrRegisterHistogram 

func GetOrRegisterHistogram(nameFormat string, nameArgs ...interface{}) metrics.Histogram

func GetOrRegisterMeter 

func GetOrRegisterMeter(nameFormat string, nameArgs ...interface{}) metrics.Meter

func GetOrRegisterTimer

func Init 

func Init()

This package should be imported before any metric (e.g. timer, histogram) created. Because, `metrics.Enabled` in go-ethereum is `false` by default, which leads to noop metric created for static variables in any package.

In addition, this package should be imported after the initialization of viper and logrus.

func NewHistogram 

func NewHistogram() metrics.Histogram

Types

type InputBlockMetric 

type InputBlockMetric struct{}

InputBlockMetric is used to add metrics for input block parameter.
