[Flent-users] Testing multiple station in once
Hi all, I'm playing around with flent now, According to this post: http://blog.cerowrt.org/post/fq_codel_on_ath10k/ Flent can be used to test multiple stations in once, but how can I do that? After reading the documentation, I didn't find the options relative to this. Thanks, Louie. ___ Flent-users mailing list Flent-users@flent.org http://flent.org/mailman/listinfo/flent-users_flent.org

You can use the rtt_fair_var* tests; these take multiple hostnames and will run a TCP flow and a ping to each. Similarly, you can pass multiple hostnames to voip_hosts to get a VoIP stream to each. > Also, when I testing VoIP, and control host have setup ITGRecv: > > $ flent voip -p totals -H 192.168.177.157 --control-host > 192.168.177.157 --ditg-control-port 9000 -v > > Output said it will end in 60 seconds, but after about 5 minutes, it > still hangs at there, how can I know flent is running which command in > this test case? D-ITG is finicky and easy to anger. I would suggest you try using irtt instead: https://github.com/peteheist/irtt/ - if you install this on the client and run the server on the server hosts, Flent should pick it up automatically and use it for both UDP ping and VoIP tests. > And the last, what does it mean about server and client in flent? > > If I have a network like this: > > Control -> AP -> Multiple stations > > And I want to test AP tx performance, should I set control as server, > and use flent on stations, or flent on control with netperf server on > stations. In this case (which is also what I use in my setup), the easiest is to run Flent on the control node and pass the client hostnames to Flent as the 'servers', using the rtt_fair_var* tests as noted above. The notion of upload/download will be wrong from a client PoV, but you can fix that with the --swap-up-down parameter, or simply relabel the plots afterwards (I do the latter). -Toke ___ Flent-users mailing list Flent-users@flent.org http://flent.org/mailman/listinfo/flent-users_flent.org
Re: [Flent-users] Testing with multiple station, voip and some question between server client
Cool, thanks for your reply, this should be added to the quick-start page, where can I make a PR for flent.org? Also, I found that currently, PyPI flent isn't using the 1.1.1-git version (is 1.1.1), thus at that point I only saw D-ITG in conf and flent.org documentation. After looking in mailing-list I saw the commit and install flent from GitHub with `Flent 1.1.1-git-2d0cd05` which include the itff runner so can use it. And documentation didn't mention this.

The flent.org page is the HTML output of the documentation in the doc/ subdirectory (build with spinx; `make doc` from the flent repo root builds it. A pull request would be much appreciated! > Also, I found that currently, PyPI flent isn't using the 1.1.1-git > version (is 1.1.1), thus at that point > I only saw D-ITG in conf and flent.org documentation. Yeah, a new release is needed with this feature, but we ran out of time before the holidays. Should get around to that within a week or two :) > After looking in mailing-list I saw the commit and install flent from > GitHub with `Flent 1.1.1-git-2d0cd05` which include the itff runner so > can use it. And documentation didn't mention this. I'll be sure to update the documentation before making the new release! -Toke ___ Flent-users mailing list Flent-users@flent.org http://flent.org/mailman/listinfo/flent-users_flent.org

Commit 46a2154 introduce the bug that completly remove import
matplotlib, and fixed at commit 2d0cd05a. But still have bug when
opening a new data file, it will hang by this:
Exception in thread Thread-3:

RuntimeError: main thread is not in main loop
After checking the code, adding one line
matplotlib.use("Agg")
to fix this problem.

[Flent-users] Now raw data found for series TCP download / TCP upload / Ping (ms) avg?
Hi all, When I palying around with flent, using flent-gui to open a data file which run with: $ flent rtt_fair_var -p totals -H 192.168.177.157 -H netperf.bufferbloat.net -o file.png -v It will came with this error output: No raw data found for series TCP download avg, falling back to computed values No raw data found for series TCP upload avg, falling back to computed values No raw data found for series Ping (ms) avg, falling back to computed values Is this what test case just not test it, or my config with netperf or iperf have some problem? Thanks, Louie. ___ Flent-users mailing list Flent-users@flent.org http://flent.org/mailman/listinfo/flent-users_flent.org
