Abstract

Windows Error Reporting (WER) is a distributed system that automates the processing of error reports coming from an installed base of a billion machines. WER has collected billions of error reports in ten years of operation. It collects error data automatically and classifies errors into buckets, which are used to prioritize developer effort and report fixes to users. WER uses a progressive approach to data collection, which minimizes overhead for most reports yet allows developers to collect detailed information when needed. WER takes advantage of its scale to use error statistics as a tool in debugging; this allows developers to isolate bugs that could not be found at smaller scale. WER has been designed for large scale: one pair of database servers can record all the errors that occur on all Windows computers worldwide.
调试中的(非常)大:十年的实现和经验
Windows错误报告(WER)是一个分布式系统,可以自动处理来自已安装的十亿台机器的错误报告。在十年的运行中,WER收集了数十亿份错误报告。它自动收集错误数据,并将错误分类到不同的桶中,这些桶用于确定开发人员工作的优先级,并向用户报告修复。WER使用一种渐进式的方法来收集数据,这使大多数报告的开销最小化,但允许开发人员在需要时收集详细信息。WER利用其规模优势,使用错误统计作为调试工具;这使得开发人员可以隔离在较小范围内无法发现的bug。WER是为大规模设计的:一对数据库服务器可以记录全球所有Windows计算机上发生的所有错误。
