Functions

func InitMetricScope

func InitMetricScope(
	cfg *Config,
	rootMetricScope string,
	metricFlushInterval time.Duration) (tally.Scope, io.Closer, *nethttp.ServeMux)

InitMetricScope initialize a root scope and its closer, with a http server mux

func SafeScopeName

func SafeScopeName(name string) string

SafeScopeName returns a safe scope name that removes dash which is not allowed in tally

Types

type Closer

type Closer func()

Closer closes the runtime metrics collection

func StartCollectingRuntimeMetrics

func StartCollectingRuntimeMetrics(
	scope tally.Scope,
	enabled bool,
	collectInterval time.Duration,
) Closer

StartCollectingRuntimeMetrics starts generating runtime metrics under given metrics scope with the collectInterval

type Config

type Config struct {
	MultiReporter  bool                   `yaml:"multi_reporter"`

}

Config will be containing the metrics configuration
