第10章 Prometheus远程存储方案

Prometheus当前存在的问题

解决方案：

1.Thanos

2.VirtoriaMetrics

Thanos架构

VirtoriaMetrics架构

VirtoriaMetrics

vmstorage：数据存储以及查询结果返回，默认端口为 8482

vminsert：数据录入，可实现类似分片、副本功能，默认端口 8480

vmselect：数据查询，汇总和数据去重，默认端口 8481

vmagent：数据指标抓取，支持多种后端存储，会占用本地磁盘缓存，默认端口 8429

vmalert：报警相关组件，不如果不需要告警功能可以不使用该组件，默认端口为 8880
