Methods

attemptCancelled()

public void attemptCancelled()

Add an annotation that the attempt was cancelled by the user.

attemptFailed(Throwable error, Duration delay)

public void attemptFailed(Throwable error, Duration delay)

Adds an annotation that the attempt failed, but another attempt will be made after the delay.

Parameters
NameDescription
errorThrowable
delayorg.threeten.bp.Duration

attemptFailedRetriesExhausted(Throwable error)

public void attemptFailedRetriesExhausted(Throwable error)

Adds an annotation that the attempt failed and that no further attempts will be made because retry limits have been reached.

Parameter
NameDescription
errorThrowable

attemptPermanentFailure(Throwable error)

public void attemptPermanentFailure(Throwable error)

Adds an annotation that the attempt failed and that no further attempts will be made because the last error was not retryable.

Parameter
NameDescription
errorThrowable

attemptStarted(int attemptNumber)

public void attemptStarted(int attemptNumber)

Adds an annotation that an attempt is about to start. In general this should occur at the very start of the operation. The attemptNumber is zero based. So the initial attempt will be 0.

Parameter
NameDescription
attemptNumberint

attemptStarted(Object request, int attemptNumber)

public void attemptStarted(Object request, int attemptNumber)

Adds an annotation that an attempt is about to start with additional information from the request. In general this should occur at the very start of the operation. The attemptNumber is zero based. So the initial attempt will be 0.

Parameters
NameDescription
requestObject
attemptNumberint

attemptSucceeded()

public void attemptSucceeded()

Adds an annotation that the attempt succeeded.

batchRequestSent(long elementCount, long requestSize)

public void batchRequestSent(long elementCount, long requestSize)

Adds an annotation that a batch of writes has been flushed.

Parameters
NameDescription

requestSizelong

connectionSelected(String id)

public void connectionSelected(String id)

Annotates the operation with selected connection id from the ChannelPool.

Parameter
NameDescription
idString

inScope()

public ApiTracer.Scope inScope()

Asks the underlying implementation to install itself as a thread local. This allows for interop between clients using gax and external resources to share the same implementation of the tracing. For example OpenCensus will install a thread local that can read by the GRPC.

Returns
TypeDescription
ApiTracer.Scope

lroStartFailed(Throwable error)

public void lroStartFailed(Throwable error)

Signals that the initial RPC for the long running operation failed.

Parameter
NameDescription

lroStartSucceeded()

public void lroStartSucceeded()

Signals that the initial RPC successfully started the long running operation. The long running operation will now be polled for completion.

operationCancelled()

public void operationCancelled()

Signals that the operation was cancelled by the user. The tracer is now considered closed and should no longer be used.

operationFailed(Throwable error)

public void operationFailed(Throwable error)

Signals that the overall operation has failed and no further attempts will be made. The tracer is now considered closed and should no longer be used.

Parameter
