Input parameters for starting network capture.
struct DDS_StringSeq NDDS_Utility_NetworkCaptureParams_t::transports |
List of transports to capture.
Network Capture will only save RTPS frames if the associated transport protocol is part of this sequence.
[default] Empty sequence initializer. This means that by default all transports will be captured.
NDDS_Utility_NetworkCaptureContentKindMask NDDS_Utility_NetworkCaptureParams_t::dropped_content |
Exclude contents from the capture file.
It accepts values from NDDS_Utility_NetworkCaptureContentKind and NDDS_Utility_NetworkCaptureContentKindMask .
We can choose to exclude user data or encrypted content from the capture file.
[default] No content is excluded - NDDS_UTILITY_NETWORK_CAPTURE_CONTENT_MASK_DEFAULT.
NDDS_Utility_NetworkCaptureTrafficKindMask NDDS_Utility_NetworkCaptureParams_t::traffic |
Traffic direction to capture.
It accepts values from NDDS_Utility_NetworkCaptureTrafficKind and NDDS_Utility_NetworkCaptureTrafficKindMask .
[default] Capture both inbound and outbound traffic - NDDS_UTILITY_NETWORK_CAPTURE_TRAFFIC_MASK_DEFAULT.
DDS_Boolean NDDS_Utility_NetworkCaptureParams_t::parse_encrypted_content |
If secure traffic should be decrypted or not.
[default] DDS_BOOLEAN_FALSE
struct DDS_ThreadSettings_t NDDS_Utility_NetworkCaptureParams_t::checkpoint_thread_settings |
The properties of the checkpoint thread.
The checkpoint thread is a per-participant thread responsible for reading frames from a queue and saving them to disk (as soon as they are produced).
The members that can be configured are:
DDS_Long NDDS_Utility_NetworkCaptureParams_t::frame_queue_size |
Size of the frame queue (Bytes).
Network capture enqueues frames before saving them to disk, which takes place in a separate thread.
Network Capture does not block if the queue becomes full. Attempting to enqueue a frame with a full frame queue will fail (frame won't be captured) with a log message.
The size of the queue is dependent on the network traffic (amount of frames that we want to capture) and system resources (how fast we can capture frames).
[default] 2097152 (2MB).
