Telegraf: Rename multiples fields to only one field

Hi

I tried with the processor for rename multiples columns to only one colunm, but this save only last field.

Example:
[INPUT_1] = 10 -> INPUT
[INPUT_2] = 20 -> INPUT
[INPUT_3] = 30 -> INPUT

In this example the value send to output is “INPUT” = “30” by this is the last value.

I see the code of the processor and believe that this is for the key value is replace ever for the last key write, Exist of the posibilitys the create a new metrics ?.

I see documentation of plugins proccesor but not understan how to add new metrics for no remplace befores metrics.

How is the method?.

Another question, they used any virtual machine with the enviroment of dev for goland and telegraf ?

Thanks.
