Types

type Collector

type Collector interface {
	ApiErrorOccurred()
	TraceDownloadFailed()
	ServerPanicked(reason string)
	CadenceHeightIndexed(height uint64)
	EVMHeightIndexed(height uint64)
	EVMTransactionIndexed(count int)
	EVMAccountInteraction(address string)
	MeasureRequestDuration(start time.Time, method string)
	OperatorBalance(account *flow.Account)
	AvailableSigningKeys(count int)
}

func NewCollector

func NewCollector(logger zerolog.Logger) Collector

type DefaultCollector

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

func (*DefaultCollector) ApiErrorOccurred

func (c *DefaultCollector) ApiErrorOccurred()

func (*DefaultCollector) AvailableSigningKeys

func (c *DefaultCollector) AvailableSigningKeys(count int)

func (*DefaultCollector) CadenceHeightIndexed

func (c *DefaultCollector) CadenceHeightIndexed(height uint64)

func (*DefaultCollector) EVMAccountInteraction

func (c *DefaultCollector) EVMAccountInteraction(address string)

func (*DefaultCollector) EVMHeightIndexed

func (c *DefaultCollector) EVMHeightIndexed(height uint64)

func (*DefaultCollector) EVMTransactionIndexed

func (c *DefaultCollector) EVMTransactionIndexed(count int)

func (*DefaultCollector) MeasureRequestDuration

func (c *DefaultCollector) MeasureRequestDuration(start time.Time, method string)

func (*DefaultCollector) OperatorBalance

func (c *DefaultCollector) OperatorBalance(account *flow.Account)

func (*DefaultCollector) ServerPanicked

func (c *DefaultCollector) ServerPanicked(reason string)

func (*DefaultCollector) TraceDownloadFailed

func (c *DefaultCollector) TraceDownloadFailed()

type HttpHandler

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

HttpHandler is a thin middleware for gathering metrics about http request. It makes no decision about error handling. If one occurred, we log it and pass request on to the underlying handler to make a decision

func NewMetricsHandler

func NewMetricsHandler(handler http.Handler, collector Collector, log zerolog.Logger) *HttpHandler

func (*HttpHandler) ServeHTTP

func (h *HttpHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)
