var ErrNotFound = errors.New("trace not found")
ErrNotFound is reported by Store.Get when a trace is not found.
Functions ¶

Types ¶
type EventIterator ¶
type EventIterator func(*tracepb2.TraceEvent) bool
An EventIterator is called once for each event in a trace, sequentially and in streaming fashion as events are read from the store.
If it returns false the stream is aborted and the function is not called again.
type ListEntryIterator ¶
type ListEntryIterator func(*tracepb2.SpanSummary) bool
A ListEntryIterator is called once for each trace matching the query string, sequentially and in streaming fashion as traces are read from the store.
If it returns false the listing operation is stopped and the function is not called again.
type NewSpanEvent ¶ added in v1.29.1
type NewSpanEvent struct { AppID string TestTrace bool Span *tracepb2.SpanSummary }
type Query ¶
type Query struct { AppID string Service string Endpoint string Topic string Subscription string TraceID string MessageID string TestFilter *bool // nil means both test and non-test traces are returned Tags []Tag // StartTime and EndTime specify the time range to query. // If zero values they are not bounded. StartTime, EndTime time.Time IsError *bool // nil means both successes and failures are returned // Minimum and maximum duration (in nanoseconds) to filter requests for. // If MaxDurMicros is 0 it defaults to no limit. MinDurNanos, MaxDurNanos uint64 Limit int // if 0 defaults to 100. }
type RecordData ¶
type Recorder ¶
type Recorder struct {
// contains filtered or unexported fields
}
func NewRecorder ¶
func (*Recorder) RecordTrace ¶
func (h *Recorder) RecordTrace(data RecordData) error
type Store ¶
type Store interface { // WriteEvents persists requests in the store. WriteEvents(ctx context.Context, meta *Meta, events []*tracepb2.TraceEvent) error // List lists traces that match the query. // It calls fn for each trace read; see ListEntryIterator. List(ctx context.Context, q *Query, iter ListEntryIterator) error // Get streams events matching the given trace id. // fn may be called with events out of order. // If the trace is not found it reports an error matching ErrNotFound. Get(ctx context.Context, appID, traceID string, iter EventIterator) error // Listen listens for new spans. Listen(ch chan<- NewSpanEvent) }
Store is the interface for storing and retrieving traces.
