This configuration will populate `opentelemetry.proto.collector.v1.logs.ExportLogsServiceRequest.resource_logs <https://github.com/open-telemetry/opentelemetry-proto/blob/main/opentelemetry/proto/collector/logs/v1/logs_service.proto>`_. In addition, the request start time is set in the dedicated field. [#extension: envoy.access_loggers.open_telemetry] [#next-free-field: 8]

  OpenTelemetry `Resource <https://github.com/open-telemetry/opentelemetry-proto/blob/main/opentelemetry/proto/logs/v1/logs.proto#L51>`_ attributes are filled with Envoy node info. Example: ``resource_attributes { values { key: "region" value { string_value: "cn-north-7" } } }``.

• optional opentelemetry.proto.common.v1.AnyValue body = 2

  OpenTelemetry `LogResource <https://github.com/open-telemetry/opentelemetry-proto/blob/main/opentelemetry/proto/logs/v1/logs.proto>`_ fields, following `Envoy access logging formatting <https://www.envoyproxy.io/docs/envoy/latest/configuration/observability/access_log/usage>`_.
