管理监控系统
你的监控系统与你运行的任何其他服务一样重要。因此，应该给予其适当的关注度。
实现配置即代码（
Configuration as Code
）
将系统配置视为代码，并将其存储在版本控制系统中是一种常见的做法，这种方式
提供了一些明显的好处：保存了更改历史记录、把特定变更和任务跟踪系统关联起来、
提供了更简单的回滚功能和语法语义检查

，以及强化了代码评审流程的执行。
我们强烈建议将监控配置视为代码（有关配置的更多信息，请参阅第

的系统。这种方法是
诸多只读取一个配置文件的开源二进制软件包的标准配置方法。一些第三方的解决
方案（如
grafanalib
）也启用了这种方法，而不是传统上只通过图形界面配置组件。
鼓励一致性
那些大型公司往往拥有多个工程团队，而且这些团队都在使用监控系统，这就需要
一种良好的平衡：一方面有一种集中式的方法提供了所需要的一致性，另一方面，
各个团队可能也希望完全控制自己配置设计。
正确的解决方案取决于你的组织。

的方式是随着时间不断发展演进的，逐渐
融合成为一套统一的框架，并以一个集中式的服务运行。由于一些原因，这个解决
方案只适用于我们。单一框架使工程师在切换团队的时候也能够更快地轻松上手，
而且一起调试时的协作也更加容易了。我们还有一个集中式的仪表板服务，每个团
队都可找到并访问自己的仪表板。如果你轻松地理解了其他团队的仪表板，那么你
就可以更快地调试你和他们的问题。
如果可能的话，我们要把基础监控的实施化为无形。如果你的所有服务 ...
