数据现在只写到同端口的实例上

[xxx1204]

请问 backends 里的多个实例。怎么将数据写到另一个实例，现在我只能写到一个实例8087，8086 没有数据，但是数据库在4个实例都有，现在measurements只有在8087上的实例有。

curl -X POST "http://127.0.0.1:7076/query?u=admin&p=xiebin1204" --data-urlencode 'q=CREATE DATABASE test WITH DURATION 1d REPLICATION 1 SHARD DURATION 1h NAME "liquid"'

measurements里配多个backends。

@xxx1204 proxy是按照分库进行设计的，同一组db和measurement，只会往每个circle中的一个influxdb写，你可以多试几个不同的measurement，就会分配到8086的实例上。
不同circle之间的数据是相互备份的关系
