If I want to remove previously imported data, how do I do that?
you have to make a distinction between deleting the index in the backend (Elasticsearch) and deleting references to the data from the frontend that is the “Index Pattern Search” in the datamodel configuration and then the dashboard etc.
The data in the backend can only be deleted with a low level query. You open the “dev tool” (wrench icon) and issue a delete command (just write “delete namehere”. . you get an autocompelte with the names of the indexes).
The index pattern search and all the other objects can be deleted from the UI e.g. in the datamodel you have a delete button on the top right. Other objects (E.g. visualizations) can be removed from the Object section in the management.
Hopes this helps… until we add this option in the UI
Okay. I will try what you said. Thanks.
