# 为什么会有本书

Prometheus是一款优秀的监控平台，而平时最常见的组合是Prometheus+Alertmanager+Grafana。

Prometheus主动拉取数据并存储，配置告警，在触发阈值后，会将告警推送至Alertmanager，Alertmanager根据告警规则进行处理，选择通知用户等；而Grafana主动拉取Prometheus数据进行数据可视化展示。

本书相比较其他的教程，为从零到有的部署，作为一款多年的系统，在数据采集后的教程网上就很欠缺了，对于一款监控系统来说，虽然对应的项目有对应的规则，但是肯定是有一套通用的规则，比如针对Nginx、MySQL这类服务器、数据库，在部署完成Prometheus，把这些通用的监控纳入进来，让系统真正地跑起来，再考虑那些其他的项目，这是一种很简单的逻辑。

本书仍然创作中，大纲可能会进行大量的增删改。
