Is there a way how to get statistics from ASTF

[Petr Olejník]

Hello,

ASTF is great but we would need to see the statistics provided by trex console in time since they change a lot and also they fall back to zero after the end of the test.

We would like to run a test for an hour for example and see how the statistics changes in time. A simple CSV would be ok.

The Stateless GUI looks like exactly what I need. But it is only for stateless, not for ASTF.

Regards

Petr

Hi Petr, 

There isn't anything like the Stateless GUI for ASTF, but we provide the full API in Python. This means, that you can collect statistics using a simple Python script and store them in any format you want.

-- The API function that collects the statistics: https://trex-tgn.cisco.com/trex/doc/cp_astf_docs/api/client_code.html?highlight=get_stats#trex.astf.trex_astf_client.ASTFClient.get_stats

-- A simple example on how to collect stats using the API: https://trex-tgn.cisco.com/trex/doc/trex_astf.html#_tutorial_python_automation_v2_47_and_up

Note that you need to modify this example to get statistics not only after the traffic has finished.

Thanks, 

Bes

Hello Bes,

thank you very much for your answer. Sorry for maybe a dumb question but how should I run the example script? If I run

python astf_example.py

I get:

Traceback (most recent call last):
  File "astf_example.py", line 3, in <module>
    import astf_path
ImportError: No module named astf_path

Thanks in advance for helping a newbie.

Hi Petr, 

Might it be that you are not running it from the correct directory?

It seems to me that it works as expected:

$ pwd

/auto/srg-sce-swinfra-usr/emb/users/bdollma/trex/trex-core/scripts/automation/trex_control_plane/interactive/trex/examples/astf

$ python3

Python 3.4.3 (default, Mar 23 2016, 14:21:41)

[GCC 4.7.2 20121109 (Red Hat 4.7.2-8)] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import astf_path

>>>

Thanks,

Thank you, that was it :-)
