Saving and Opening Stream Files¶
To open a stream file, first select the appropriate port in the ports list and then goto Streams | Open Streams (alternatively use the right-click context menu).
To save the streams configured on a port to a file, first select the appropriate port in the ports list and then goto Streams | Save Streams (alternatively use the right-click context menu).
Prior to v1.2.0, stream related menu items were under the File menu
The following file formats are supported -
- Ostinato native
pcapcapture format (starting v0.4)
pdmlXML format (starting v0.4)
pyPython Script (starting v0.7)
Native OSTM format¶
This is the default and recommended format.
PCAP and PDML formats¶
If you want to use Ostinato generated packets with other tools, use the PCAP format which is widely supported.
Timestamps in exported PCAP files
Starting v1.2, exported PCAP files use nanosecond timestamps. Prior version used microsecond precision timestamps.
PDML is a XML representation of packets and their attributes.
Python script (export only)¶
You can export the configured streams as a python script for use with the Ostinato Python API.
This provides an easy to way to create and test traffic streams using the GUI and then use the exported python script for automation.
See Python API Guide for more details.
