组件介绍：
| 组件介绍 | 功能 |
| Prometheus Server | 主要用于抓取数据和存储时序数据，另外还提供查询和 Alert Rule 配置管理。 |
| client libraries | 用于对接 Prometheus Server，可以查询和上报数据。 |
| push gateway | 用于批量，短期的监控数据的汇总节点，主要用于用于业务数据汇报等。 |
| exporters | 用来汇报数据，列如汇报机器数据的node_exporter，汇报 MongDB 信息的 MongDB exporter 等等 |
| altertmanager |
我们的监控节点使用docker起镜像，Prometheus使用二进制安装
