通过将每个问题都视为新问题来处理，我们可以确定在生产过程中出现问题时真正发生
了什么，而不是简单地将其与最近的类似问题进行模式匹配。这使得对给传统方法带来
最大挑战的系统进行有效故障定位成为可能。
我们现在可以快速有效地诊断以下问题：
•
跨越多个运行时的微服务和请求。
•
面对多种存储系统，不需要每个系统的专业知识。
•
多租户和运行时服务器端代码和查询；我们可以轻松地深入了解个人用户体验，以
确切了解发生了什么。
即使我们剩下的少量单体系统使用了无聊的技术，但所有可能的问题都被很好地理解
了，我们仍然获得了一些收获。我们不一定会发现任何新的东西，但结果是我们能够更
快、更自信地发布软件。
在
Parse
，个人提升最快的途径是学习如何使用可观测的系统。通过在适当的抽象级别
收集应用程序遥测数据，围绕用户体验进行聚合，并能够实时分析，我们获得了神奇的
见解。一旦我们有能力提出任何问题，链路追踪每一个步骤，并通过观测应用程序的输
出来了解任何内部系统状态，我们就消除了传统工具的局限性。一旦有了可观测性，我
们就能够使自己的实践现代化。

控方法过渡到使用现代分布式系统和可观测性来扩展其实践。
