On the production environment we've setup 3 loggers. Right now on production the rails default and custom info logs are being sent even when we set the log_level to be :warn. The weird thing is that we have exactly the same config for staging and development, on the other environments is working just fine; only production has problems.

# production.rb

file_logger = ActiveSupport::Logger.new(File.join('log', "#{Rails.env}.log").to_s, 5, 10.megabytes) # keep 5 files with 10 megas
appsignal_logger = Appsignal::Logger.new("#{Rails.application.class.module_parent_name}_#{Rails.env}")

logger = AppLogger.new do |cacheable_logger|
  cacheable_logger.broadcast_to file_logger
  cacheable_logger.broadcast_to appsignal_logger
  cacheable_logger.broadcast_to ActiveSupport::Logger.new($stdout)

  cacheable_logger.appsignal_logger = appsignal_logger
end

config.logger = ActiveSupport::TaggedLogging.new(logger)
config.log_level = :warn

# AppLogger inherits from ActiveSupport::BroadcastLogger
# AppLogger < ActiveSupport::BroadcastLogger

Appsignal logs dashboard

I changed the log levels, I removed the custom logs, I even overwrote the custom class that inherits from ActiveSupport::BroadcastLogger to unsubscribe from the Appsignal logger when the severity is info
