Detailed Description

Input parameters for starting network capture.

Member Data Documentation

transports

StringSeq transports = new StringSeq()

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.

dropped_content

int dropped_content = NetworkCaptureContentKind.MASK_DEFAULT

Exclude contents from the capture file.

It accepts values from com.rti.ndds.utility.NetworkCaptureContentKind .

We can choose to exclude user data or encrypted content from the capture file.

[default] No content is excluded - com.rti.ndds.utility.NetworkCaptureContentKind.MASK_DEFAULT.

traffic

int traffic = NetworkCaptureTrafficKind.MASK_DEFAULT

Traffic direction to capture.

It accepts values from com.rti.ndds.utility.NetworkCaptureTrafficKind .

[default] Capture both inbound and outbound traffic - com.rti.ndds.utility.NetworkCaptureTrafficKind.MASK_DEFAULT.

parse_encrypted_content

boolean parse_encrypted_content = false

If secure traffic should be decrypted or not.

[default] com.rti.dds.infrastructure.false

checkpoint_thread_settings

ThreadSettings_t checkpoint_thread_settings = new ThreadSettings_t()

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:

• com.rti.dds.infrastructure.ThreadSettings_t.mask. Default value of (com.rti.dds.infrastructure.ThreadSettingsKind.THREAD_SETTINGS_PRIORITY_ENFORCE | com.rti.dds.infrastructure.ThreadSettingsKind.THREAD_SETTINGS_STDIO).
• com.rti.dds.infrastructure.ThreadSettings_t.priority. Platform-dependent - Consult Platform Notes for additional details.
• com.rti.dds.infrastructure.ThreadSettings_t.stack_size. Platform-dependent - Consult Platform Notes for additional details.

frame_queue_size

int frame_queue_size = 2097152

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).
