#03 Set Sidekiq and rails log level using single environment variable

Sidekiq by default logs at info level and do not respect the rails log level. This can be problematic in environments where you are running rails at warn or error. Log stream will be flooded by log entries from sidekiq.

To control sidekiq and rails logging level using a single environment variable, add this to your config/initializers/sidekiq.rb file.

Sidekiq.configure_server do |config|
  config.logger.level = Logger.const_get(ENV.fetch('LOG_LEVEL', 'info').upcase.to_s)
end

LOG_LEVEL variable is used to set the rails log level in config/environments/production.rb.

config.log_level = ENV.fetch('LOG_LEVEL', 'info').to_sym
