|
||
## Summary
|
||
- 核心主题：家庭环境监控完整解决方案
|
||
- 问题域：主机监控、容器监控、服务可用性监控、日志聚合
|
||
- 方法/机制：Docker Compose一键部署Prometheus+Grafana监控栈
|
||
- 结论/价值：构建工作室级监控体系
|
||
|
||
## Key Claims
|
||
- node_exporter采集主机指标（CPU/内存/磁盘/网络）
|
||
- cAdvisor采集容器资源使用情况
|
||
- blackbox_exporter探测HTTP/TCP服务可用性
|
||
- Alertmanager支持邮件/Slack/Webhook告警
|
||
|
||
## Key Concepts
|
||
- [[监控体系]]：Prometheus + Grafana核心架构
|
||
- [[指标采集]]：Pull模式主动采集exporter数据
|
||
- [[容器监控]]：cAdvisor监控Docker容器
|
||
- [[合成监测]]：blackbox_exporter做主动探测
|
||
- [[告警分发]]：Alertmanager统一告警路由
|
||
|
||
## 架构组件
|
||
|
||
### 数据采集层
|
||
| Exporter | 用途 | 端口 |
|
||
|----------|------|------|
|
||
| node_exporter | 主机指标 | 9100 |
|
||
| cAdvisor | 容器指标 | 8080 |
|
||
| blackbox_exporter | HTTP/TCP探测 | 9115 |
|
||
|
||
### 存储层
|
||
| 组件 | 用途 |
|
||
|------|------|
|
||
| Prometheus | 时序数据库/告警规则 |
|
||
| Alertmanager | 告警分发 |
|
||
|
||
### 展示层
|
||
| 组件 | 用途 |
|
||
|------|------|
|
||
| Grafana | 可视化仪表盘/告警 |
|
||
|
||
## 推荐监控项
|
||
- 主机：CPU使用率>85%告警
|
||
- 磁盘：剩余空间<10%告警
|
||
- 内存：可用内存<15%告警
|
||
- 容器：重启次数>0告警
|
||
- HTTP：探测失败连续2分钟告警
|
||
- TLS：证书剩余<14天告警
