Hi, 

Have you consider to use the API for that?

Have a look into the stl/examples folder how to do it.

You would be able to run the TUI and script in parallel.

Thanks

Hanoh

Hi,

The TUI uses the API to get the raw information and print it to the screen.

If you want to print to a file (the TUI results), it probably possible with a little hacks in the code.

The right way is to take an API example and save the JSON result to a file.

It would be simpler to parse.

But again this

It depends on the bigger picture you want to achive.

Hi Hanoh,

I am run the tui and script on separate console. Since the Latency logs dynamically changing and only the Max value remains at the end of test.
How can i capture the Average and minimum latency for a port.

Also i need this information to be stored in a log file or can i redirect the tui output.


Thanks
Zafirul

Hi,

I think I understand your issue now,

Let's take this example 

https://github.com/cisco-system-traffic-generator/trex-core/blob/master/scripts/automation/trex_control_plane/stl/examples/stl_flow_latency_stats.py

In this example we start the traffic and *wait* to the result while you want the result while it is running right?

    c.start(ports = [tx_port])
    c.wait_on_traffic(ports = [tx_port])

There is another API that you can convert the 

wait_on_traffic to 

a loop that read the counters, save them to a file and exit once the traffic finished.

Will some example like that help you?
