最近读Sentinel源码,发现里面多出一个扩展模块 sentinel-prometheus-metric-exporter,基于之前对Sentinel的使用经验,对其必要性产生怀疑,理由如下: 我们知道,在Sentinel中有个sentinel-dashboard模块,其中有个类src/main/java/com/alibaba/csp/sentinel/dashboard/repository/metric/InMemoryMetricsRepository.java, 这个类是在内存中保留了各节点5分钟的监控信息,既然监控信息已经收集起来了, 为什么不直接在这里扩展一个metric-exporter,所有的节点监控都在这里暴露了,这样不用麻烦在每个应用内开一个metric-exporter,应用只用关注自己的业务开发即可。
