Getting Participant Protocol Status

16.3.14 Getting Participant Protocol Status

Statistics about corrupted RTPS messages received by the participant can be obtained from the DomainParticipantProtocolStatus.

Table 16.6 DDS_DomainParticipantProtocolStatus
Type	Field Name	Description
DDS_LongLong	corrupted_rtps_message_count	The number of corrupted RTPS messages detected by the participant.
DDS_LongLong	corrupted_rtps_message_count_change	The incremental change in the number of corrupted messages detected since the last time the status was read.
DDS_Time_t	last_corrupted_message_timestamp	The timestamp of the last corrupted RTPS message detected by the participant.

You can get the DomainParticipantProtocolStatus by using the get_participant_protocol_status() operation. The WireProtocolQosPolicy’s compute_crc and check_crc must be enabled in the publishing and subscribing applications, respectively, when the protocol status is obtained.
