## Source File
|
||
- [[raw/Home Office/家庭监控方案：Prometheus + Grafana + Node Exporter + cAdvisor +Blackbox.md]]
|
||
|
||
## Summary
|
||
- 核心主题：家庭实验室监控方案设计（Prometheus + Grafana 栈）
|
||
- 问题域：家庭服务器监控与告警
|
||
- 方法/机制：Prometheus 采集+告警，Grafana 可视化，node_exporter/cAdvisor/blackbox_exporter 分别采集主机/容器/网络指标
|
||
- 结论/价值：完整的开源监控栈，可在 NAS/Ubuntu Server 通过 Docker 一键部署
|
||
|
||
## Key Claims
|
||
- 监控覆盖：主机层（CPU/内存/磁盘）、容器层（运行状态/重启次数）、服务层（HTTP可用性/TLS证书）
|
||
- 核心组件：prometheus + grafana + alertmanager + node_exporter + cAdvisor + blackbox_exporter
|
||
- Docker Compose 一键部署，配置文件包括 prometheus.yml、alerts.yml、alertmanager/config.yml
|
||
- 告警规则：HostHighCPU（>85%）、HostLowDisk（<10%）、HostLowMemory（<15%）、HTTPProbeFailed、TLSCertExpiring（<14天）
|
||
- Grafana 导入 Dashboard ID：Node Exporter Full (1860)、cAdvisor (14282)、Blackbox (7587)

|
||
- [[node_exporter]]：主机硬件指标采集
|
||
- [[cAdvisor]]：容器资源指标采集
|
||
- [[blackbox_exporter]]：HTTP/TCP 网络探测
|
||
- [[Alertmanager]]：告警分发与抑制
|
||
|
||
