功能介绍：

为了方便CITA服务的运维，我们开发了 CITA 的监控服务，可用于监控节点中CITA的服务运行情况，包括区块链数据、CITA进程的存活监控、运行环境监控、故障自动告警通知。

软件架构：基于 Prometheus 框架开发；使用 Grafana 做可视化面板；使用 Alertmanager 做告警消息分发；运行架构上分为用于数据存储、信息展示、告警分发的 Server 端；区块链数据、软件进程、运行环境监控指标收集的 Agent 端；各端均使用微服务架构分离功能职责，并使用 Docker Compose 部署方式解决服务的依赖管理，轻松做到一行命令更新、启动服务。

• CITA 服务进程监控
