Rails日誌過於冗長

如何防止Rails日誌過多？以下是我的production.log文件中的一個典型跟蹤，許多分支和緩存命中......它在開發中很有用，但我不希望它在我的生產環境中使用。Rails日誌過於冗長

感謝的對你有所幫助

使用** [Lograge]（https://github.com/roidrage/lograge）**，最好寶石我找到了清理Rails日誌記錄 – Yarin 2014-01-07 14:51:55

在Rails 4將有清理日誌設置：

config.action_view.logger = nil

爲了實現在Rails 3中，你必須猴子補丁的ActionView：

module ActionView 
    class LogSubscriber < ActiveSupport::LogSubscriber 
    def logger 
     @memoized_logger ||= Logger.new('/dev/null') 
    end 
    end 
end

FWIW，這個猴子補丁顯然會導致文件句柄泄漏（至少在Rails 3.2.12中）。我建議用'@memoized_logger || = Logger.new（'/ dev/null'）'替換'Logger.new（'/ dev/null'）'。這裏的經驗苦澀的聲音。 :) – bheeshmar 2013-11-21 21:23:35

感謝您的報告。我編輯了我的答案。 – sailor 2014-01-02 16:06:20

爲了在日誌級別調試時保持部分日誌記錄的啓用，您可以使用'@memoized_logger || = Rails.logger.debug？？ super：Logger.new（'/ dev/null'）' – robd 2014-05-22 10:27:21

你需要設置你的config.log_level不同。瞭解有關Log Levels。

例如，添加以下config/evironments/production.rb

config.log_level = :warn

此致很可能設置爲:debug或:info。

問題是當日志級別設置爲警告，我什麼也沒有在我的日誌文件中。我想要的基本信息記錄如「處理由HomeController＃索引爲HTML」或「在369毫秒完成200 OK（Views：272.3ms | ActiveRecord：8.1ms）」 – sailor 2012-08-17 09:49:53

我把這個在我初始化程序來monkeypatch某些日誌記錄去調試，而不是信息：

module ActionView 
    class LogSubscriber 
    def render_template(event) 
     message = "Rendered #{from_rails_root(event.payload[:identifier])}" 
     message << " within #{from_rails_root(event.payload[:layout])}" if event.payload[:layout] 
     message << " (#{event.duration.round(1)}ms)" 
     debug(message) 
    end 
    alias :render_partial :render_template 
    alias :render_collection :render_template 
    end 
end 

module ActionController 
    class LogSubscriber 
    # Use debug logging for read_fragment 
    # %w(write_fragment read_fragment exist_fragment? expire_fragment expire_page write_page).each do |method| 
    %w(read_fragment).each do |method| 
     class_eval <<-METHOD, __FILE__, __LINE__ + 1 
     def #{method}(event) 
      return unless logger.info? 
      key_or_path = event.payload[:key] || event.payload[:path] 
      human_name = #{method.to_s.humanize.inspect} 
      debug("\#{human_name} \#{key_or_path} (\#{event.duration.round(1)}ms)") 
     end 
     METHOD 
    end 
    end 
end
