：监控测试环境层次
1.
二进制报告
：检查它导出的度量指标变量的值，在特定条件下是否按预期产生了
变化。
2.
监控配置
：确保规则评估产生了预期的结果，并在特定条件下产生预期的告警。
3.
告警配置
：根据告警标签的值测试，看它所生成的告警是否到达了预期。
如果你无法通过仿真的方式测试监控，或者你所处的阶段就是无法进行监控测试，
请考虑另外搭建一套运行的系统，暴露（导出）那些预先设定的指标，如请求数和
错误数。你可以使用此系统来验证仿真的时间序列和告警。在配置之后，你的告警
规则很可能数月或数年都不会触发，因而你需要确信当指标超过某个阈值时，工程
师会收到正确的有意义的告警通知。

SRE
通常需要非常熟悉服务的监
控系统，以及服务的各种功能。如果没有这方面的知识，
SRE
可能不知道该看哪里，
如何识别异常行为，或者如何在紧急情况下找到所需的信息。
我们希望通过指出监控系统里有用的功能及其原因，帮助你评估你的监控策略与需
求的匹配程度、探索你能利用到的一些其他功能、思考那些你可能想要做出的变化。
你可能会发现，将一些指标源和监控策略记录在一起的方式将会很有帮助。这种准
确的融合是需要高度依赖于上下文的。确保采集的指标都服务于特定的目的。这样
做是为了更好地进行容量规划，协助排错（

通知。
