## 定义
系统外部可推断其内部状态的能力。包含三大支柱Metrics指标、Logs日志、Traces链路追踪
## 核心组成
- **Metrics**Prometheus 采集的数值型时序数据,如 CPU 使用率、请求延迟
- **Logs**:事件发生的文本记录,如应用错误日志
- **Traces**:请求在分布式系统中的完整调用链路,如 OpenTelemetry
## 工具链
- Metrics[[Prometheus]] + [[Grafana]]
- Logs[[Loki]] + Promtail + Grafana
- TracesJaeger/Zipkin + Grafana Tempo
## 在 Wiki 中的角色
- [[家庭监控方案 Prometheus + Grafana + Node Exporter + cAdvisor + Blackbox]] 覆盖 Metrics 和部分合成监测
- 扩展路径:加 Loki + Promtail 补全日志覆盖
