Possible to add/force a static tag=value pair in /etc/telegraf/telegraf.d?

Telegraf

So I have many conf files in /etc/telegraf/telegraf.d
a.conf
b.conf
c.conf

Am I able to add a static tag = “value” into a.conf which is not impacting all of other conf files?

I’ve tried to use [global_tags] but that literally adds that tag into all measurements being collected by telegraf agent run on that server.

Example of my hypothetical use in which I’d like to force a new tag “url” which is NOT present in the json data:

[[inputs.file]]
  interval = "5m"
  files = ["/tmp/coingecko.json"]
  name_override = "coingecko"
  data_format = "json"
  url = "coingecko.com"

Hi,

Sounds like you want to add tags to a specific input plugin. You can do this by adding the following “tags” to your config above:

[[inputs.file]]
  interval = "5m"
  files = ["/tmp/coingecko.json"]
  name_override = "coingecko"
  data_format = "json"
  url = "coingecko.com"

  [inputs.file.tags]
    tag1 = "foo"
    tag2 = "bar"

There is not a way to do this per-file, as all the files are read in together. Also, note that these tag declarations need to come at the end of the TOML definition.

Cool, that might work. But your statement…

…got me worried a lil bit…so let me ask this first:
So in case in file b.conf I have also [[inputs.file]] plugin collecting data completely unrelated to what’s in a.conf
Are the tags defined in a.conf being written in the measurement defined in b.conf?

No - only if you setup global tags.
