将prometheus采集的数据远程存储到influxdb中

这个比较简单，

https://docs.influxdata.com/influxdb/v1.7/supported_protocols/prometheus

只需要更改prometheus.yaml配置 文件。

    global:
      # 抓取的间隔时间
      scrape_interval: 20s
      # How long until a scrape request times out.
      scrape_timeout: 10s
      # 计算告警触发条件的周期
      evaluation_interval: 20s
    # 告警规则文件
    rule_files:
      - '/etc/prometheus-rules/*.rules'
    remote_write:
      - url: "http://xxxx:8086/api/v1/prom/write?db=prometheus"

    # remote_read:
    #   - url: "http://xxxx:8086/api/v1/prom/read?db=prometheus"
