<<extension>> The status of a reader's internal protocol related metrics, like the number of samples received, filtered, rejected; and status of wire protocol traffic.
| System::Int64 DDS::DataReaderProtocolStatus::received_sample_count |
The number of samples received by a DataReader.
Depending on how the DDS::DataReaderProtocolStatus was obtained this may count samples coming from a specific DataWriter or from all the DataWriters that are matched with the DataReader.
If the DDS::DataReaderProtocolStatus is obtained using the DDS::DataReader::get_datareader_protocol_status operation then it will count samples from any DataWriter. If the DataReaderProtocolStatus is obtained using the DDS::DataReader::get_matched_publication_datareader_protocol_status then it will count the samples for the DataWriter specified as a parameter to the function.
Duplicate samples arriving from the DataWriter(s) (e.g. via multiple network paths) are detected prior to increasing this counter. The duplicate samples are counted by DDS::DataReaderProtocolStatus::duplicate_sample_count.
If the DataReader has specified a ContentFilter the received samples that do not pass the filter are part of this counter. The filtered samples are counted by DDS::DataReaderProtocolStatus::filtered_sample_count.
Samples rejected because they do not fit on the DataReader Queue are also part of this counter.
Note the received_sample_count counts samples received from all DataWriters and it does not necessarily match the number of samples accepted into the DataReader Queue. This is because:
Note that when data is fragmented, this statistic is updated when all of the fragments required to reassemble a sample are received, not when individual fragments are received.
| System::Int64 DDS::DataReaderProtocolStatus::received_sample_count_change |

When using DDS::ReliabilityQosPolicyKind::RELIABLE_RELIABILITY_QOS; if the DataReader received samples out-of-order, they are stored internally until the missing samples are received. The number of out-of-order samples that the DataReader can keep is set by DDS::RtpsReliableReaderProtocol_t::receive_window_size. When the received window is full any out-of-order sample received will be dropped.

The number of NACK fragment bytes that have been sent from a DataReader to a DataWriter.
