Renaming auto extracted fields

[SudarshanS]

After parsing my json fields the auto extracted fields have format like this a{}.b and a{}.b{}.c and so on.
When i try to add auto extracted field to data model I'm getting an exception,

"Field Name can not contain whitespace, double quotes, single quotes, curly braces or asterisks. " And this exception makes sense as my auto extracted field name contains curly braces, so how can i remove curly braces. I tried to use the concept of field alias as mentioned in https://answers.splunk.com/answers/307993/is-there-a-bug-in-splunk-6-with-adding-an-attribut.html. But I'm not able to add field alias in Data Model, Is there an example how to add field alias in Data Model.

use the rename command:
... | rename a{}.b as A, a{}.b{}.c{} as B .....
http://docs.splunk.com/Documentation/SplunkCloud/6.6.0/SearchReference/Rename
there are other options out there as well. eval command for example

Hi Adonio,

Thanks for your reply. using spath and rename can be done on search head, how can i use it in data model ?

[adonio]

couple of options here regarding a data model.
first, you can extract the fields first and have the data model root search or child search or constraint have the fields you extracted with spath and renamed mentioned.
other option is: -> add field -> eval expression -> eval "A" = a{}.b
i think it supposed to work
hope it helps
