I think it makes more sense to move this into an initializer that just gets run once. Maybe just something like this:

```ruby
module Capacitor
  def init
    self.log_level = log_level
  end

private

  def log_level
    redis.get 'log_level'
  end
end
```

And then Capacitor.init can just be called from a [railtie](https://github.com/remind101/capacitor/blob/d4c56bfa8a6f597c01eed963bf25093ad7e06dec/lib/capacitor/railtie.rb).
