Remove Default Index?

Hi,
I wanted to know if it's possible to disable the default index on Kibana dashboard or change the default page with a different one?

The default index can be changed in Settings -> Advanced.

or by clicking the star when you select an index pattern in settings.
If one isn't selecting you'll be asked to choose one.

If you want to change the default page, in config/kibana.yml you can set kibana.defaultAppId to a different page, ie "dashboard".

There isn't a current way to disable having a default index but if you want to file an enhancement request with your use case you can do so at https://github.com/elastic/kibana/issues.
