Prometheus 是云原生计算基金会(CNCF)的毕业项目,专为动态云环境设计的开源监控与告警系统。它采用拉取(Pull)模式采集指标,支持多维数据模型(由指标名称和键值对标签定义),并通过强大的 PromQL 查询语言实现灵活的数据聚合与分析。Prometheus 自带告警管理功能,可基于规则触发通知,并集成 Alertmanager 进行去重、分组和路由。其生态丰富,与 Kubernetes、Docker 等容器平台无缝对接,是微服务监控的首选方案。虽然原生存储为本地磁盘,但可通过 Thanos 或 Cortex 实现长期持久化。适合需要实时监控、快速故障定位的运维场景,尤其适合云原生架构。
