Log errors in file

Question

How do I log all process failures in a file instead of tty? I read in the documentation that there are some standard Erlang modules that can do this (SASL, error_logger), but, unfortunately, I did not find any clean examples.

Answer 1

Start your erl node with

erl -boot start_sasl -sasl sasl_error_logger \{file,\"path/to/logfile.log\"\}
