前言
VictoriaMetrics 是一个支持水平扩展的时序数据库，可以作为 Prometheus的远端存储，并且实现了 PromSQL，可以直接通过 VictoriaMetrics 查询时序数据，避开 Prometheus 查询时的单点瓶颈。
部署Victoria Metrics 集群
VictoriaMetrics 集群版本的架构如下：
vminsert 和 vmselect 是无状态的写入、查询节点，vmstorage 是有状态的存储节点。数据平均分配到 vmstorage 节点，每个 vmstorage 分担一部分数据，没有冗余，如果 vmstorage 节点丢失，那么数据对应丢失。
三个组件的镜像：
victoriametrics/vminsert:v1.34.0-cluster
victoriametrics/vmselect:v1.34.0-cluster
victoriametrics/vmstorage:v1.34.0-cluster
vmstorage:
image: victoriametrics/vmstorage:v1.34.0-cluster
privileged: true
volumes:
- ./data/victoria:/data
command:
- "-storageDataPath=/data"
- "-retentionPeriod=1"
ports:
- "8482:8482"
- "8400:8400"
- "8401:8401"
vmselect:
image: victoriametrics/vmselect:v1.34.0-cluster
command:
- "-selectNode=vmselect:8481"
- "-storageNode=vmstorage:8401"
ports:
- 8481:8481/tcp
vminsert:
image: victoriametrics/vminsert:v1.34.0-cluster
command:
- "-storageNode=vmstorage:8400"
ports:
- "8480:8480"分别访问下面三个地址，查看组件的状态数据：
insert: http://127.0.0.1:8480/metrics、
select: http://127.0.0.1:8481/metrics、
storage：http://127.0.0.1:8482/metrics、配置Prometheus

通过 VictoriaMetrics 的 API 查询：
curl -g 'http://127.0.0.1:8481/select/0/prometheus/api/v1/series' --data-urlencode 'match[]=requests_total{}' |jq
