Functions ¶
func NormalizeServiceName ¶
NormalizeServiceName converts service name to a lowercase string that is safe to use in metrics
Types ¶
type APIHandler ¶
type APIHandler struct {
// contains filtered or unexported fields
}
APIHandler handles all HTTP calls to the collector
func NewAPIHandler ¶
func NewAPIHandler( jaegerBatchesHandler JaegerBatchesHandler, ) *APIHandler
NewAPIHandler returns a new APIHandler
func (*APIHandler) RegisterRoutes ¶
func (aH *APIHandler) RegisterRoutes(router *mux.Router)
RegisterRoutes registers routes for this handler on the given router
type CountsBySpanType ¶
type CountsBySpanType struct { // Received is the actual number of spans received from upstream Received metrics.Counter // Rejected is the number of spans we rejected (usually due to blacklisting) Rejected metrics.Counter // ReceivedBySvc maintain by-service metrics for a format type ReceivedBySvc metricsBySvc }
CountsBySpanType measures received, rejected, and receivedByService metrics for a format type
type FilterSpan ¶
FilterSpan decides whether to allow or disallow a span
type JaegerBatchesHandler ¶
type JaegerBatchesHandler interface { // SubmitBatches records a batch of spans in Jaeger Thrift format SubmitBatches(ctx thrift.Context, batches []*jaeger.Batch) ([]*jaeger.BatchSubmitResponse, error) }
JaegerBatchesHandler consumes and handles Jaeger batches
func NewJaegerSpanHandler ¶
func NewJaegerSpanHandler(logger *zap.Logger, modelProcessor SpanProcessor) JaegerBatchesHandler
NewJaegerSpanHandler returns a JaegerBatchesHandler
type Option ¶
type Option func(c *options)
Option is a function that sets some option on StorageBuilder.
type ProcessSpan ¶
ProcessSpan processes a Domain Model Span
func ChainedProcessSpan ¶
func ChainedProcessSpan(spanProcessors ...ProcessSpan) ProcessSpan
ChainedProcessSpan chains spanProcessors as a single ProcessSpan call
type ProcessSpans ¶
ProcessSpans processes a batch of Domain Model Spans
type SpanProcessor ¶
type SpanProcessor interface { // ProcessSpans processes model spans and return with either a list of true/false success or an error ProcessSpans(mSpans []*model.Span, spanFormat string) ([]bool, error) }
SpanProcessor handles model spans
func NewSpanProcessor ¶
func NewSpanProcessor( spanWriter spanstore.Writer, opts ...Option, ) SpanProcessor
NewSpanProcessor returns a SpanProcessor that preProcesses, filters, queues, sanitizes, and processes spans
type SpanProcessorMetrics ¶
type SpanProcessorMetrics struct { // SaveLatency measures how long the actual save to storage takes SaveLatency metrics.Timer // InQueueLatency measures how long the span spends in the queue InQueueLatency metrics.Timer // SpansDropped measures the number of spans we discarded because the queue was full SpansDropped metrics.Counter // BatchSize measures the span batch size BatchSize metrics.Gauge // size of span batch // QueueLength measures the size of the internal span queue QueueLength metrics.Gauge // ErrorBusy counts number of return ErrServerBusy ErrorBusy metrics.Counter // SavedBySvc contains span and trace counts by service SavedBySvc metricsBySvc // spans actually saved // contains filtered or unexported fields }
SpanProcessorMetrics contains all the necessary metrics for the SpanProcessor
func NewSpanProcessorMetrics ¶
func NewSpanProcessorMetrics(serviceMetrics metrics.Factory, hostMetrics metrics.Factory, otherFormatTypes []string) *SpanProcessorMetrics
NewSpanProcessorMetrics returns a SpanProcessorMetrics
func (*SpanProcessorMetrics) GetCountsForFormat ¶
func (m *SpanProcessorMetrics) GetCountsForFormat(spanFormat string) CountsBySpanType
GetCountsForFormat gets the countsBySpanType for a given format. If none exists, we use the Unknown format.
type ZipkinSpansHandler ¶
