No output when using lager dynamically on detached node [JIRA: RIAK-2301]

[malotte]

I'm using lager dynamically, i.e. adding debug tracing during execution, but when I try to do this on a detached erlang-node (that I have attached to) I get no debug output, neither in the shell nor in the files I have specified as backends for info and error in the application environment. I don't want to have debug output generated during normal execution, as when I specify a file backend for the debug level, only occasionally. Am I doing something wrong or isn't it possible?

Shell: (hoc33@venus)2> lager:trace_console([{module, seaz_ws}], debug). {ok,{lager_console_backend,[{module,seaz_ws}],debug}}

sys.config: {lager, [{log_root, "/var/erlang/hoc33/log/lager"}, {handlers, [ {lager_console_backend, [debug, {lager_default_formatter, [date, " ", time," [",severity,"] ",pid, " ", module, ":", line, " ", message, "\n"]}]}, {lager_file_backend, [{file, "error.log"}, {level, error}, {size, 10485760}, {date, "$D0"}, {count, 5}]}, {lager_file_backend, [{file, "console.log"}, {level, info}, {size, 10485760}, {date, "$D0"}, {count, 5}]} ]} ]},

We have a ticket open now to investigate this but I'm not sure offhand why this is happening.

OK. Thanks for looking at it.

There was another issue #301 which may be related to how console messages don't travel over disterl. Just wondering if that's what you're hitting here.

I'm going to close this since its been several months since the last update. Please reopen if needed. Thanks.

Sorry, I did not understand that I was supposed to investigate #301. Could you please explain how you think this is related?

And how do I reopen?
