[erlang-questions] When does lager logs into crash.log?
Fri Jan 22 22:11:01 CET 2016
from what I read about the error_logger "Error, warning and info events
are sent to the error logger from the Erlang runtime system and the
different Erlang/OTP applications." So, I guess, errors in
non-supervised code are also sent to the error_logger. But not to
lager's crash file. Actually this badmatch error is not reported
anywhere. How can I make lager report it?
