Graylog does not show index created by elasticsearch

Hi

I am trying to manage an index from graylog which is created with elasticsearch using curl command, but it seems that I cant find it through graylog API, can any one tell me what is the problem?

Regards

you can only see/work with indices that are created from Graylog. External created indices can not be used with Graylog.

Thank you for the quick reply
