完整的错误如下：

level=debug ts=2021-08-16T09:07:43.412451Z caller=handler.go:355 component=receive component=receive-handler msg="failed to handle request" err="store locally for endpoint : conflict"

开始以为是 thanos receive 命令行中配置了receive.local-endpoint参数导致的，去掉参数仍然不行。

prometheus中的关键配置为：

# prometheus.yaml

remote_write:

  - url: "http://127.0.0.1:10908/api/v1/receive"

---

thanos receiver的启动命令行为：

thanos  receive \

    --tsdb.path "./20210816/" \

    --grpc-address 0.0.0.0:10907 \

    --http-address 0.0.0.0:10909 \

    --receive.replication-factor 1 \

    --label "receive_replica=\"0\"" \

    --label "receive_cluster=\"eu1\"" \

    --remote-write.address 0.0.0.0:10908 \

    --log.level=debug \

    --log.format=logfmt
