Prometheus（普罗米修斯）——适合k8s和docker的监控系统

<p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-p" style="line-height: 1.8;">Prometheus（普罗米修斯）是一套开源的监控&amp;报警&amp;时间序列数据库的组合.由SoundCloud公司开发。</span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;">&nbsp;</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-p" style="line-height: 1.8;">Prometheus基本原理是通过HTTP协议周期性抓取被监控组件的状态，这样做的好处是任意组件只要提供HTTP接口就可以接入监控系统，不需要任何SDK或者其他的集成过程。这样做非常适合虚拟化环境比如VM或者Docker 。</span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;">&nbsp;</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-p" style="line-height: 1.8;">Prometheus应该是为数不多的适合Docker、Mesos、Kubernetes环境的监控系统之一。近几年随着k8s的流行，prometheus成为了一个越来越流行的监控工具。</span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;">&nbsp;</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-p" style="line-height: 1.8;">而且Prometheus是开源的，真是我等伸手党的福音。</span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;">&nbsp;</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-h3" style="line-height: 1.8;">架构</span></p><div class="img-container" style="color: rgb(51, 51, 51);

color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;">&nbsp;</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-p" style="line-height: 1.8;">在业务层用作埋点系统 Prometheus支持各个主流开发语言（Go，java，python，ruby官方提供客户端，其他语言有第三方开源客户端）。我们可以通过客户端方面的对核心业务进行埋点。如下单流程、添加购物车流程。在应用层用作应用监控系统 一些主流应用可以通过官方或第三方的导出器，来对这些应用做核心指标的收集。如redis,mysql。在系统层用作系统监控 除了常用软件， prometheus也有相关系统层和网络层exporter,用以监控服务器或网络。集成其他的监控 prometheus还可以通过各种exporte，集成其他的监控系统，收集监控数据，如AWS CloudWatch,JMX，Pingdom等等。不要用Prometheus做什么</span></p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;">&nbsp;</p><p style="margin: 10px auto; color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif;"><span class="bjh-p" style="line-height: 1.8;">prometheus也提供了Grok exporter等工具可以用来读取日志，但是prometheus是监控系统，不是日志系统。应用的日志还是应该走ELK等工具栈。</span></p><p style="margin: 10px auto;

margin: 10px auto;">本文介绍在k8s集群中使用node-exporter、prometheus、grafana对集群进行监控。<br>其实现原理有点类似ELK、EFK组合。node-exporter组件负责收集节点上的metrics监控数据，并将数据推送给prometheus, prometheus负责存储这些数据，grafana将这些数据通过网页以图形的形式展现给用户。</p><p style="color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; margin: 10px auto;">在开始之前有必要了解下Prometheus是什么?<br>Prometheus （中文名：普罗米修斯）是由 SoundCloud 开发的开源监控报警系统和时序列数据库(TSDB).自2012年起,许多公司及组织已经采用 Prometheus,并且该项目有着非常活跃的开发者和用户社区.现在已经成为一个独立的开源项目。Prometheus 在2016加入 CNCF ( Cloud Native Computing Foundation ), 作为在 kubernetes 之后的第二个由基金会主持的项目。 Prometheus 的实现参考了Google内部的监控实现，与源自Google的Kubernetes结合起来非常合适。另外相比influxdb的方案，性能更加突出，而且还内置了报警功能。它针对大规模的集群环境设计了拉取式的数据采集方式，只需要在应用里面实现一个metrics接口，然后把这个接口告诉Prometheus就可以完成数据采集了，下图为prometheus的架构图。</p><p style="color: rgb(51, 51, 51);

margin: 10px auto;">&nbsp;</p><p style="color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; margin: 10px auto;">Prometheus的特点：<br>1、多维数据模型（时序列数据由metric名和一组key/value组成）<br>2、在多维度上灵活的查询语言(PromQl)<br>3、不依赖分布式存储，单主节点工作.<br>4、通过基于HTTP的pull方式采集时序数据<br>5、可以通过中间网关进行时序列数据推送(pushing)<br>6、目标服务器可以通过发现服务或者静态配置实现<br>7、多种可视化和仪表盘支持</p><p style="color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; margin: 10px auto;">prometheus 相关组件，Prometheus生态系统由多个组件组成，其中许多是可选的：<br>1、Prometheus 主服务,用来抓取和存储时序数据<br>2、client library 用来构造应用或 exporter 代码 (go,java,python,ruby)<br>3、push 网关可用来支持短连接任务<br>4、可视化的dashboard (两种选择,promdash 和 grafana.目前主流选择是 grafana.)<br>4、一些特殊需求的数据出口(用于HAProxy, StatsD, Graphite等服务)<br>5、实验性的报警管理端(alartmanager,单独进行报警汇总,分发,屏蔽等 )</p><p style="color: rgb(51, 51, 51); font-family: verdana, Arial, Helvetica, sans-serif; margin: 10px auto;">promethues 的各个组件基本都是用 golang 编写,对编译和部署十分友好.并且没有特殊依赖.基本都是独立工作。<br><br></p><h3 style="color: rgb(0, 0, 0); font-family: verdana, Arial, Helvetica, sans-serif;
