Prometheus 将数据远程写入 InfluxDB 存储

Prometheus 将数据远程写入 InfluxDB 存储

• InfluxDB 1.x 提供了直接写入数据的 http 接口，Prometheus 可以直接写入，但是 InfluxDB 2.x 删除了这个接口。

• InfluxDB 2.x 引入了新的组件 Telegraf，必须借助 Telegraf 才可以将 Prometheus 的数据写入到 InfluxDB 2.x 中。

InfluxDB 2.0 使用 Prometheus 架构图

InfluxDB 2.0 不使用 Prometheus 架构图

InfluxDB 2.0 与 Telegraf 如何结合配置

测试: 启动，收集一点数据，再卸载容器，再启动容器，查看刚刚收集的数据是否存在，存在就说明持久化成功
