Prometheus系列第九篇一核心之micrometer架构

架构图

• MeterRegistry有两大类[SimpleMeterRegistry,CompositeMeterRegistry]单注册源和多注册源
• MeterRegistry针对不同数据源实现包含
• • HealthMeterRegistry
• • PrometheusMeterRegistry
• • AtlasMeterRegistry etc…
• PrometheusMeterRegistry负责创建micrometer的度量,比如PrometheusCounter,DefaultGauge等,同时为每个度量创建一个MicrometerCollector
• MicrometerCollector负责注册prometheus的CollectorRegistry,采集时通过MicrometerCollector收集PrometheusCounter或者其他度量的指标信息

系统模块

micrometer有两个大的模块

总结

• 本文概述了prometheus与micrometer的结合,以及micrometer的作用
• micrometer的core模块集成了大量的中间件度量采集工具,从而提供了开箱即用的一整套工具
