prometheus远程连接m3db实现存储

如果是prometheus server配置文件添加如下：

remote_read:
  - url: "http://m3coordinator.m3db.svc.cluster.local:7201/api/v1/prom/remote/read"
    # To test reading even when local Prometheus has the data
    read_recent: true

remote_write:
  - url: "http://m3coordinator.m3db.svc.cluster.local:7201/api/v1/prom/remote/write"
    # To differentiate between local and remote storage we will add a storage label
    write_relabel_configs:
      - target_label: metrics_storage
        replacement: m3db_remote

如果是prometheus-operator里的prometheus资源添加如下

remoteRead:
  - url: "http://m3coordinator.m3db.svc.cluster.local:7201/api/v1/prom/remote/read"
    readRecent: true
remoteWrite:
  - url: "http://m3coordinator.m3db.svc.cluster.local:7201/api/v1/prom/remote/write"
    writeRelabelConfigs:
      - targetLabel: metrics_storage
        replacement: m3db_remote
