如何从Telegraf配置控制石墨场/标签顺序/层次结构？

Question

我们刚刚开始使用iptables telegraf输入收集iptables指标并将其发送到graphite输出。问题是，生成的Graphite标签/字段层次结构与配置不匹配。

我们正尝试使用以下配置选项对其进行控制：

[[outputs.graphite]]
  prefix = "telegraf"
  template = "host.tags.measurement.field"

这是完整的配置：

[global_tags]
   location = "dc1"
   tier = "live"
   role = "intfw"
   lsbdistdescription = "wheezy"
[agent]
    hostname = "intfw1-test"
[[processors.regex]]
  namepass = ["iptables"]
  [[processors.regex.tags]]
  key = "ruleid"
  pattern = "[:.,\\s]"
  replacement = "_"
[[outputs.graphite]]
  prefix = "telegraf"
  template = "host.tags.measurement.field"
[[inputs.iptables]]
  table = "filter"
  chains = ["INPUT","FORWARD","OUTPUT"]

由于这种配置，我们期望石墨场的层次结构如下：

telegraf ( == outputs.graphite prefix )
└── intfw1-test ( == host from outputs.graphite template )
    └── dc1 ( == first global tag from outputs.graphite template tags (global_tags.location))
        └── live  ( == global_tags.tier)
            └── intfw ( == global_tags.role)
                └── wheezy ( == global_tags.lsbdistdescription )
                    └── iptables ( == measurment(inputs.iptables))
                        └── filter  ( == first tag from inputs.iptables, table)
                            └── INPUT( == 2nd tag from inputs.iptables, chain)
                                └── allow_monitoring ( == 3rd tag from inputs.iptables, ruleid)
                                    └── pkts.wsp (field)

但是，实际上，我们得到了以下结构：

telegraf
└── intfw1-test
    └── INPUT
        └── dc1
            └── wheezy
                └── intfw
                    └── allow_monitoring
                        └── filter
                            └── live
                                └── iptables
                                    └── pkts.wsp

即global_tags和tags from iptables.input以某种奇怪的方式混合在一起。有没有机会通过telegraf配置来控制这种层次结构？
