telegraf - 将动态标签添加到 Telegraf 输入

Question

我们正在使用 telegraf从 AWS 收集 CloudWatch 数据并将其输出到 InfluxDB。

我们需要给输入添加动态标签，s.t if "instancId == 12345" , 添加标签 "user = 3"
有没有办法做到这一点？

看看 processors .如果您只想使用一组已知值，我认为 enum 将是最好的选择。以下是针对您的案例更新的示例:

[[processors.enum]]
  [[processors.enum.mapping]]
    ## Name of the field to map
    field = "instancId"

    ## Destination field to be used for the mapped value.  By default the source
    ## field is used, overwriting the original value.
    dest = "user"

    ## Default value to be used for all values not contained in the mapping
    ## table.  When unset, the unmodified value for the field will be used if no
    ## match is found.
    default = 0

    ## Table of mappings
    [processors.enum.mapping.value_mappings]
      123 = 1
      1234 = 2
      12345 = 3
