独自コントローラーログの設定

around_action :logging_filter

def logging_filter
  class_name = "#{params[:controller].capitalize}Controller"
  method_name = params[:action]
  login = current_user.login if current_user

  start_time = Time.now_msec
  trace_start = {type: "controller", se_flg: "start", user: login, class_name: class_name, method_name: method_name, apptime: "", params: params}
  logger.debug trace_start

  ret = yield

  end_time = Time.now_msec
  trace_end = {type: "controller", se_flg: "end", user: login, class_name: class_name, method_name: method_name, apptime: "#{(end_time - start_time).to_s}ms", params: ""}
  logger.debug trace_end
end

renderingログをLTSV形式に分割

def convert_hash_if_rendering_log(msg)
  return msg unless msg =~ /  Rendered .*/
  messages = {}
  messages[:type] = "rendering"
  msg =~ /  (Rendered) (.*) (.*)/
  messages[:uri] = $2
  messages[:apptime] = $3.gsub(/[\(\)]/, "")
  messages
end

Request GET、POSTのログをLTSV形式に分割

def convert_hash_if_request_log(msg)
  return msg unless msg =~ /Started (GET|POST) .*/
  messages = {}

  msg =~ /(Started) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*).*/
  messages[:type] = $2
  messages[:uri] = $3
  messages[:host] = $5
  messages
end

CompletedログをLTSV形式に分割

def convert_hash_if_complete_log(msg)
  return msg unless msg =~ /Completed .*/
  messages = {}
  messages[:type] = "completed"

  msg =~ /(Completed) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*) (.*)/
  messages[:status] = $2
  messages[:success] = $3
  messages[:apptime] = $5
  messages[:apptime_view] = $7
  messages[:apptime_active_record] = $10.chop!
  messages
end

カスタムロガー全体のコード

config/environment.rb

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Project::Application.initialize!

    ret << "progname:[#{progname}]" if progname
    msg = convert_hash_if_rendering_log msg
    msg = convert_hash_if_request_log msg
    msg = convert_hash_if_complete_log msg
    if (msg.instance_of?(Hash))
      msg.each {|k, v|ret << "#{k}:[#{v}]"}
    else
      ret << "msg:[#{msg}]"
    end
    ret.join("\t") + "\n"

    app_time_active_record = $10.nil? ? "" : $10.chop! 
    messages[:apptime_active_record] = app_time_active_record
    messages
  end
end

module ActionController
  class LogSubscriber < ActiveSupport::LogSubscriber
    # 標準のControllerトレースログを無効化
    # application_controller.rbで独自定義したログを利用する。
    def start_processing(event)
    end
