Hi everybody.  
i just removed .alerts-security.alerts-default-0000 suddenly after i was working with rules and made my dashboards.  
is there a way to recreate it? because it gives me this error:

Bulk indexing of signals failed: no such index [.alerts-security.alerts-default] and [require\_alias] request flag is [true] ...  
Elk Version : 8.5.2

You might need to manually create the underlying index for it to reattach to the alias. Otherwise try restarting Elasticsearch and it should do that for you.

Why was it removed?

Hi.

It removed manually because i wanted to clear the alerts.  
I thought it may create it again when it creates new alerts.
