hi friends

I would like to know if there is a code to clean up the kibana dev tool...  
In these days I created many templates, many mapping and indexes  
I know there are commands

DELETE / my\_index  
DELETE / all  
DELETE /my\_template

but if i want to reset all configuration?

(i ask this because when i create a new index (with name egual to old name) i see the old mapping.  
for example in the photo i see old ge\_poit mapping for my new index)

And if i use GET \_template i see this

there are many lines  
how i can delete it?

DELETE \_template/\* should do it.

You probably want to take a backup of some sort though.

Hi  
What do the "Delete \_template/\* " do?  
Delete all template?  
Can i make it without problem?  
Does it work to delete old fields mapping?  
I dont understand why when i delete the template, the pattern and the associated indexs and i create new index and new patter with an egual name as previous, i see ok kibana old mapping fields

Yes.

No, just the template for any future indices.

There must be another template that matches. Are you sure you are deleting everything? If so what commands are you running.
