## 定义
|
||||
Synthetic Monitoring,通过主动发起探测请求(HTTP/TCP/DNS/TLS)模拟用户行为,检测服务可用性和性能。与 Real User Monitoring(RUM)相对。
|
||||
|
||||
## 核心指标
|
||||
- **probe_success**:探测是否成功(0/1)
|
||||
- **probe_duration_seconds**:探测响应时间
|
||||
- **probe_http_status_code**:HTTP 响应码
|
||||
- **probe_ssl_earliest_cert_expiry**:TLS 证书到期时间戳
|
||||
|
||||
## 工具对比
|
||||
| 工具 | 类型 | 特点 |
|
||||
|-----|------|-----|
|
||||
| [[blackbox_exporter]] | Prometheus 生态 | 细粒度 PromQL 指标,适合内嵌 Grafana |
|
||||
| [[Uptime Kuma]] | 独立开源 | 友好 UI,适合外网监控 |
|
||||
|
||||
## 在 Wiki 中的角色
|
||||
- [[家庭监控方案 Prometheus + Grafana + Node Exporter + cAdvisor + Blackbox]] 中通过 blackbox_exporter 实现内外网 HTTP/TCP/TLS 探测
|
||||
- 监控目标:https://pq2435887bh.vicp.fun、http://shenwei-nas.vip.cpolar.cn、https://transmission.vip.cpolar.cn
|
||||
|
||||
## 告警规则
|
||||
```promql
|
||||
# 站点不可达(连续2分钟)
|
||||
probe_success == 0 for 2m
|
||||
|
||||
# TLS证书14天内到期
|
||||
probe_ssl_earliest_cert_expiry - time() < 86400 * 14
|
||||
```
