 useful in scenarios where other filters (auth, ratelimit, etc.) make
 outbound calls and have child spans rooted at the same ingress
 parent. Defaults to false.

 This field is deprecated by the
 :ref:`spawn_upstream_span <envoy_v3_api_field_extensions.filters.network.http_connection_manager.v3.HttpConnectionManager.Tracing.spawn_upstream_span>`.
 Please use that ``spawn_upstream_span`` field to control the span creation.

    • getRespectExpectedRqTimeout

      public boolean getRespectExpectedRqTimeout()
       If not set, ingress Envoy will ignore

 Envoy, when deriving timeout for upstream cluster.
      bool respect_expected_rq_timeout = 6;
      Specified by:

      Returns:
      The respectExpectedRqTimeout.

    • getSuppressGrpcRequestFailureCodeStats

      public boolean getSuppressGrpcRequestFailureCodeStats()
       If set, Envoy will avoid incrementing HTTP failure code stats
 on gRPC requests. This includes the individual status code value
 (e.g. upstream_rq_504) and group stats (e.g. upstream_rq_5xx).
 This field is useful if interested in relying only on the gRPC
 stats filter to define success and failure metrics for gRPC requests
 as not all failed gRPC requests charge HTTP status code metrics. See
 :ref:`gRPC stats filter<config_http_filters_grpc_stats>` documentation
 for more details.
      bool suppress_grpc_request_failure_code_stats = 7;
      Specified by:
      getSuppressGrpcRequestFailureCodeStats in interface RouterOrBuilder
      Returns:
