# config/environments/production.rb
config.log_level = :info
config.lograge.enabled = true
config.lograge.custom_options = lambda do |event|
request_params = event.payload[:params].except("controller", "action", "")
{ params: request_params, ip: event.payload[:ip], uid: event.payload[:user_id] }
end
这适用于后台工作人员。对于rails请求它会在一段时间后停止工作。

如上所示，只有heroku [路由器]正在登录STDOUT。 Lograge不会记录任何内容，除非出现以下内容：
2017-01-02T17:05:56.302136+00:00 app[web.1]: ** [NewRelic][2017-01-02 17:05:56 +0000 web.1 (8)] WARN : Skipping RUM instrumentation. Unable to find <body> tag in first 50000 bytes of document.
如果我看一下后台工作人员的记录，我会得到很多很好的输出，如：

任何人都知道为什么请求记录无效？
