telegraf - QuestDB 中带点的列名？

Question

我想使用 Jolokia Telegraf用于收集 JMX 指标并将其推送到 QuestDB 的插件。但是，Jolokia 插件创建带有点的标签，而 QuestDB 不支持列名称中的点。有什么办法解决这个问题吗？

Answer 1

您可以使用Telegraf rename plugin将点替换为例如下划线:_

来自重命名插件文档:

# Rename measurements, tags, and fields that pass through this filter.
[[processors.rename]]
  ## Specify one sub-table per rename operation.
  [[processors.rename.replace]]
    measurement = "network_interface_throughput"
    dest = "throughput"

  [[processors.rename.replace]]
    tag = "hostname"
    dest = "host"

  [[processors.rename.replace]]
    field = "lower"
    dest = "min"

  [[processors.rename.replace]]
    field = "upper"
    dest = "max"
