HttpLifecycleObserverRequesterFilter

GrpcLifecycleObserverRequesterFilter

All Implemented Interfaces:

HttpExecutionStrategyInfluencer, StreamingHttpClientFilterFactory, StreamingHttpConnectionFilterFactory, ExecutionStrategyInfluencer<HttpExecutionStrategy>

public final class GrpcLifecycleObserverRequesterFilter
extends HttpLifecycleObserverRequesterFilter

An HTTP requester filter that tracks events during gRPC request/response lifecycle.

This filter is recommended to be appended as the first filter at the client builder (which can be configured using GrpcClientBuilder.initializeHttp(GrpcClientBuilder.HttpInitializer)) to account for all work done by other filters. If it's preferred to get visibility in all retried or redirected requests, consider adding it after RetryingHttpRequesterFilter or RedirectingHttpRequesterFilter. If it's preferred to get visibility to information populated by other filters (like tracing keys), it can be appended after those filters.
