flent-users,

When I try to run the "bursts" test, I get an error message
complaining there is no command set for class SilentProcessRunner.
Which leaves me a bit clueless, after trying to dig something forth
from the github issue tracker. And looking at the source code for the
class. (What am I overlooking?)

(Pop!_OS 22.04 LTS)

Congratulations, you're the first person to try to use that test in a
least five years! (AFAICT it's been broken at least that long)

The immediate API issue you're seeing is fixable (pushed a fix to github
just now), but TBH I am not sure which utility that test is trying to
run. :/

It's calling a 'traffic-gen' utility, which is not really a googlable
name, and for the life of me I can't remember what that utility is
supposed to be. Do you have such a binary on your system?

No executeable by that name. :(

% which traffic-gen
traffic-gen not found


Searching the local package index gives nothing. (Neither does the 
Debian+Ubuntu package indexes)

$ apt-cache search traffic-gen
<empty output>

https://packages.debian.org/index
https://packages.ubuntu.com/


Tried on Pypi to find something by that name.

1. https://pypi.org/search/?q=trafficgen
2. https://pypi.org/search/?q=traffic-gen

The second one gives so many results. It impossible for me to pick out 
where to start looking. 🤯


The commits adding tests/bursts.conf and flent/tests/bursts_11e.conf 
gives me little information to go by concerning the traffic-gen binary.

Ah, dug out some emails which set me on the right path. Seems to be this
utility which, apparently, I wrote myself a decade ago, and then,
evidently, forgot all about:

https://github.com/tohojo/traffic-gen

Seems to work well enough, so go ahead and try it, I guess? :)

Installed the latest flent and traffic-gen from source yesterday after 
our mail conversations.

Ran into an issue with the bursts test, where the flent test continues 
to run. Resulting in the node generating traffic for the full pipe for 
hours on end. My observation is the test does not terminate for unknown 
reasons.

Found this test running from yesterday afternoon this morning still 
actively running. Which was strange. As the test duration was set to 
begin => 30s => 300s => 30s => end.

Could this happen if the node is not able to connect to the remote end 
during the test? I.e. the inband control channel is not possible (to 
little bandwidth available), due to the bandwidth just filling up the 
wired pipe... :think:

Hmm, did you pull the latest version of traffic-gen? The version on
github had a bug where it would just go into an infinite loop and never
exit (and not produce any traffic either). Fixed that yesterday, so make
sure you pull the fixed version...

Hmm. Good question

I did compile the binary yesterday afternoon. So I can only assume it 
contains the tree commits from yesterday.

It did produce *lots* of traffic. Had to terminate flent process to 
terminate the child traffic-gen processes.
Attached is the graph of the network traffic levels (in MB/s) as 
reported by Proxmox.

Ah! Seems I introduced another infinite loop while fixing the previous
one; pushed another fix, please try that...

😅 Haha,

Compiled the new version (acf8c41) and setup my scheduled 
(flent-tests.sh) job to run the bursts test (again). 🙈

Created https://github.com/tohojo/traffic-gen/issues/1 for the version 
identifier request.

So the current summary is traffic-gen correctly terminates.

But the flent test itself never terminate. The process keeps running in 
the background. Resulting in the test results being saved to disk.

Resulting in the test results *not* being saved to disk.

I fell like I am getting more gray hairs by the hours. 🤕 I cannot 
figure out why this happens.

The burst test seems to run. Flent never "completes". Resulting in no

Ending up with multiple processes still running. Having not completed 
"correctly".

It's crashing in the parsing step, leading to a hang; this is visible on
stdout, so I guess your runner script hides that?

$ ./run-flent bursts -l 10
Starting Flent 2.1.1+git.6959463f using Python 3.10.10.

Should be fixed in the latest master, please try that.

Also, BTW, not sure what your wrapper script does, but Flent has a
built-in batch run facility which may be helpful for such multi-run
tests...

True. Switched to using systemd timers instead of crontab, saving logs 
from stdout/stderr going forwards. 💾 Had not initially thought about 
logging the output from the wrapper script. 🤦

Installed the upgrade. 🤞

I wrote the wrapper script, due to not knowing about flent's batch 
capabilities initially. 🙄 Will look into the built-in batch 
capabilities instead of a wrapper script.
