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.
	StreamCompression StreamCompression `json:"streamCompression,omitempty"` // Compression format of returned stream.
}

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"` // No description.
}

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 is deprecated.
	//
	// Deprecated: Category/tag filter
	Categories *string `json:"categories,omitempty"`
	// Options is deprecated.
	//
	// Deprecated: Tracing options
	Options                      *string  `json:"options,omitempty"`
	BufferUsageReportingInterval *float64 `json:"bufferUsageReportingInterval,omitempty"` // If set, the agent will issue bufferUsage events at this interval, specified in milliseconds
	// TransferMode Whether to report trace events as series of
	// dataCollected events or to save trace to a stream (defaults to
	// `ReportEvents`).
	//
	// Values: "ReportEvents", "ReturnAsStream".
	TransferMode      *string           `json:"transferMode,omitempty"`
	StreamCompression StreamCompression `json:"streamCompression,omitempty"` // Compression format to use. This only applies when using `ReturnAsStream` transfer mode (defaults to `none`)
	TraceConfig       *TraceConfig      `json:"traceConfig,omitempty"`       // No description.
}

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 deprecated

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

SetCategories sets the Categories optional argument.
