Sidekiq Log Level not being set in production

Question

I'm running Sidekiq with Rails 5.2.3 on AWS Elastic Beanstalk. Following the instructions in the Sidekiq wiki in initializers/sidekiq.rb I've set:

Sidekiq.configure_server do |config|
   config.logger.level = Logger::WARN
end 

This works in the development environment however in production Sidekiq is still generating logs at the debug level. The Rails production logger level is set to config.log_level = :warn

Answer 1

I had a similar, but opposite problem. My production log level was set to WARN, my Sidekiq log level was set to INFO, but I kept getting only WARN logs in production.

I finally figured out you must manually override the other loggers with Sidekiq.Logging

    Sidekiq.configure_server do |config|
       config.logger.level = Logger::WARN

       Rails.logger = Sidekiq.logger
       ActiveRecord::Base.logger = Sidekiq.logger
       ActiveJob::Base.logger = Sidekiq.logger
    end

Answer 2

To use a single environment variable to control both rails and sidekiq logging behaviour.

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