Question

我正在使用Rails和Rollbar来跟踪错误，并使用Resque来处理延迟的任务。我的一名工作人员在resque GUI中出现以下错误失败：

Net::ReadTimeout
/app/vendor/ruby-2.0.0/lib/ruby/2.0.0/net/protocol.rb:158:in `rescue in rbuf_fill'

/app/app/models/shop.rb:110:in `block in bulk_scan'
/app/app/models/shop.rb:101:in `each'
/app/app/models/shop.rb:101:in `bulk_scan'
/app/app/workers/bulk_scanner.rb:9:in `perform'

但是看到有关失败的更有力的信息真的很有帮助。例如。什么是参数。通常我会将Rollbar用于此类事情，但由于某种原因它似乎没有记录此错误。

我如何修复此错误？因为我真的不知道是什么触发了它？（我的工作人员基本上是通过不同用户的一大堆API调用循环，我不知道哪一个失败了）

您可以创建自定义记录器，并使用它记录有用信息以跟踪问题。在您的worker中，添加转储可变内容等的调试语句

my_log = Logger.new("log/worker.log")

def do_stuff
  my_log.info "#do_stuff"
end

另一个选择是在代码中放置断点。您将获得一个可用于摆弄的交互式shell。

Rails：查找Resque工作程序中发生的错误。没有日志滚动条
