Prometheus是一个最初在SoundCloud上构建的监控系统。自2012年成为社区开源项目，拥有非常活跃的开发人员和用户社区。为强调开源及独立维护，Prometheus于2016年加入云原生云计算基金会（CNCF)，成为继Kubernetes之后的第二个托管项目。

原理：Prometheus的基本原理是通过各种exporter提供的HTTP协议接口周期性抓取被监控组件的状态，任意组件只要提供对应的HTTP接口就可以接入监控。不需要任何SDK或者其他的集成过程,非常适合做虚拟化环境监控系统，比如VM、Docker、Kubernetes等。互联网公司常用的组件大部分都有exporter可以直接使用，如Nginx、MySQL、Linux系统信息等。
