I have exactly the same question as this guy:
How do I log stdout from guests in Crossbar? I’ve tried stdout: log on the guest (crossbar check passes), but I get no output in neither the crossbar start output nor in .crossbar/log (which is empty), even with --loglevel trace (which doesn’t seem to affect anything?).
Also, in how do I log output from components in general (not just guests)? Just using whatever Python mechanism for logging I’d normally use? Or does Crossbar have some way of logging different components to different files et.c.?
I can’t find much in the docs on logging, except the mentioning of the --logdir and --loglevel flags for crossbar start.
