Hello I have just recently starting using Ostinato, I seem to be having trouble with avg jitter/latency not showing up no matter what I do. I am running the test on one pc and one drone I am also making sure the packets I sent are of significant length and I still get nothing. Anything helps! Thank you for your time.

Hi Matthew,

Please share -

* Your topology details including the boxes between the TX and RX port

* Does your topology include a NAT box or any other box that does DPI?

* Screenshot of the stream stats window

Can you force the UDP checksum to 0 in the stream and retry?

If the UDP checksum 0 is also not working, please share drone debug logs.

To collect debug logs, run drone with -d

Here is the Debug files and a screenshot of the stream stats window. I also changed UDP checksum to 0 and did not get any difference. Any guidance would be great!

Thank you for your time.

Hi Matthew,

Kindly also provide the topology information requested in my previous email.

Can you also capture traffic on TX and RX ports and share the PCAPs as well?

Please run the test at least for 30seconds.
