Hmm, could you try running the test from the command line and enabling
logging?

flent -v -L debug.log rrul_be <hostname>

and see if (a) that works and (b) if not, post the log somewhere?

Wait, this is the *only* output you see? This is decidedly odd. Could
you run flent under strace to see why it stops?

Okay, this is decidedly weird. From the strace output it looks like Flent is writing more stuff to stderr, but it never appears anywhere. But there is also definitely log output missing; looks like only the log lines from the settings module are actually output.

I think I have a windows 10 VM lying around somewhere, so I'll see if I can replicate this. Did you install Flent from the PPA?

There is definitely a risk that it is not something that can easily be worked around in flent. But it is still really odd behaviour...

OK, so tried this on win10 and could not reproduce the behaviour you are seeing.

The ping binary doesn't work properly on win10, though; could you try to see what happens if you run the tcp_1up_noping test?

It just occurred to me that the issue might be a hanging hostname lookup. I've added a debug statement before looking up hostnames, so if you could try running the git version with -v, it should be pretty clear if this is what is happening...

Ah, right, nice catch. Might be worth dealing with the case where the
metadata gathering commands hang. I'll look into that :)
