监控惯例
推模型
幸运的是，许多公司意识到了拉取模型的不足。以前丢失的性能数据现在可以被高精度
收集和存储，并用于解决与可用性和服务质量有关的问题。指标从不同来源被推送到统
一存储库，为我们提供了一整套数据，从而使我们可以借助这些数据来推动

响应和业
务决策。
同时，可以使用完全相同的指标来衡量系统的运行状况和可用性。
通过检测系统发送遥测数据而不是手动拉取数据，可以获得很大的灵活性。收集任务是
分散的，因此不再需要由于架构水平扩展（例如，扩展到很多节点）而垂直扩展收集系统。
系统报告它们是可用的

无须处理超时、没有断开连接或尝试重试。每个系统都可以

服务器可以通过加密来利用

套接字、消息队
列或普通的旧日志流。
在这个推模型中，我最喜欢的一个方面是可以开始分隔监控系统的功能。我们不再被迫
处理一个单一的“黑匣子”来管理
IT
资产。事实上，随着我们开始理解这些离散的功能
单元，我们便可以开始调研其他行业（例如，航空公司、医药等）并将其最佳实践应用
于自己的行业。
Graphite
适合监控领域吗
你能问这个问题，我很高兴。说实话，

几乎在监控生命周期的每一环节都能发

就是我之前提到的那些可怕的单体应用程序之一呢？

点也不是。如果你能够使用
Graphite
作为“真实来源”，那么由于其灵活的设计、定义

，它能够在监控体系结构的各个地方履行不同的职责。
