Module: Unicorn

Defined in:
lib/unicorn_logstash_patch.rb

Overview

See github.com/defunkt/unicorn/commit/5f478f5a9a58f72c0a844258b8ee614bf24ea9f7 Unicorn originally logs backtrace line by line with ‘exc.backtrace.each { |line| logger.error(line) }`. However, that means we get a separate logstash message for each backtrace which isn’t what we want. The monkey patch here overrides Unicorn’s logging of error so that we log the error and backtrace in a single message.
