Functions

func NewClient

func NewClient(conn *rpcc.Conn) *domainClient

NewClient returns a client for the Tracing domain with the connection set to conn.

Types

type BufferUsageClient

type BufferUsageClient interface {
	// Recv calls RecvMsg on rpcc.Stream, blocks until the event is
	// triggered, context canceled or connection closed.
	Recv() (*BufferUsageReply, error)
	rpcc.Stream
}

BufferUsageClient is a client for BufferUsage events.

type BufferUsageReply

type BufferUsageReply struct {
	PercentFull *float64 `json:"percentFull,omitempty"` // A number in range [0..1] that indicates the used size of event buffer as a fraction of its total size.
	EventCount  *float64 `json:"eventCount,omitempty"`  // An approximate number of events in the trace log.
	Value       *float64 `json:"value,omitempty"`       // A number in range [0..1] that indicates the used size of event buffer as a fraction of its total size.
}

BufferUsageReply is the reply for BufferUsage events.

type CompleteClient

type CompleteClient interface {
	// Recv calls RecvMsg on rpcc.Stream, blocks until the event is
	// triggered, context canceled or connection closed.
	Recv() (*CompleteReply, error)
	rpcc.Stream
}

CompleteClient is a client for TracingComplete events. Signals that tracing is stopped and there is no trace buffers pending flush, all data were delivered via dataCollected events.

type CompleteReply

type CompleteReply struct {
	Stream *io.StreamHandle `json:"stream,omitempty"` // A handle of the stream that holds resulting trace data.
}

CompleteReply is the reply for TracingComplete events.

type DataCollectedClient

type DataCollectedClient interface {
	// Recv calls RecvMsg on rpcc.Stream, blocks until the event is
	// triggered, context canceled or connection closed.
	Recv() (*DataCollectedReply, error)
	rpcc.Stream
}

DataCollectedClient is a client for DataCollected events. Contains an bucket of collected trace events. When tracing is stopped collected events will be send as a sequence of dataCollected events followed by tracingComplete event.

type DataCollectedReply

type DataCollectedReply struct {
	Value []json.RawMessage `json:"value"` //
}

DataCollectedReply is the reply for DataCollected events.

type GetCategoriesReply

type GetCategoriesReply struct {
	Categories []string `json:"categories"` // A list of supported tracing categories.
}

GetCategoriesReply represents the return values for GetCategories in the Tracing domain.

type MemoryDumpConfig

type MemoryDumpConfig []byte

MemoryDumpConfig Configuration for memory dump. Used only when "memory-infra" category is enabled.

func (MemoryDumpConfig) MarshalJSON

func (m MemoryDumpConfig) MarshalJSON() ([]byte, error)

MarshalJSON copies behavior of json.RawMessage.

func (*MemoryDumpConfig) UnmarshalJSON

func (m *MemoryDumpConfig) UnmarshalJSON(data []byte) error

UnmarshalJSON copies behavior of json.RawMessage.

type RecordClockSyncMarkerArgs

type RecordClockSyncMarkerArgs struct {
	SyncID string `json:"syncId"` // The ID of this clock sync marker
}

RecordClockSyncMarkerArgs represents the arguments for RecordClockSyncMarker in the Tracing domain.

func NewRecordClockSyncMarkerArgs

func NewRecordClockSyncMarkerArgs(syncID string) *RecordClockSyncMarkerArgs

NewRecordClockSyncMarkerArgs initializes RecordClockSyncMarkerArgs with the required arguments.

type RequestMemoryDumpReply

type RequestMemoryDumpReply struct {
	DumpGUID string `json:"dumpGuid"` // GUID of the resulting global memory dump.
	Success  bool   `json:"success"`  // True iff the global memory dump succeeded.
}

RequestMemoryDumpReply represents the return values for RequestMemoryDump in the Tracing domain.

type StartArgs

type StartArgs struct {
	Categories                   *string      `json:"categories,omitempty"`                   // Category/tag filter
	Options                      *string      `json:"options,omitempty"`                      // Tracing options
	BufferUsageReportingInterval *float64     `json:"bufferUsageReportingInterval,omitempty"` // If set, the agent will issue bufferUsage events at this interval, specified in milliseconds
	TransferMode                 *string      `json:"transferMode,omitempty"`                 // Whether to report trace events as series of dataCollected events or to save trace to a stream (defaults to ReportEvents).
	TraceConfig                  *TraceConfig `json:"traceConfig,omitempty"`                  //
}

StartArgs represents the arguments for Start in the Tracing domain.

func NewStartArgs

func NewStartArgs() *StartArgs

NewStartArgs initializes StartArgs with the required arguments.

func (*StartArgs) SetBufferUsageReportingInterval

func (a *StartArgs) SetBufferUsageReportingInterval(bufferUsageReportingInterval float64) *StartArgs

SetBufferUsageReportingInterval sets the BufferUsageReportingInterval optional argument. If set, the agent will issue bufferUsage events at this interval, specified in milliseconds

func (*StartArgs) SetCategories

func (a *StartArgs) SetCategories(categories string) *StartArgs

SetCategories sets the Categories optional argument. Category/tag filter

func (*StartArgs) SetOptions

func (a *StartArgs) SetOptions(options string) *StartArgs

SetOptions sets the Options optional argument. Tracing options

func (*StartArgs) SetTraceConfig

func (a *StartArgs) SetTraceConfig(traceConfig TraceConfig) *StartArgs

SetTraceConfig sets the TraceConfig optional argument.

func (*StartArgs) SetTransferMode

func (a *StartArgs) SetTransferMode(transferMode string) *StartArgs

SetTransferMode sets the TransferMode optional argument. Whether to report trace events as series of dataCollected events or to save trace to a stream (defaults to ReportEvents).

type TraceConfig

type TraceConfig struct {
	RecordMode           *string          `json:"recordMode,omitempty"`           // Controls how the trace buffer stores data.
