Rules: integrations and warnings

[LeitLei]

When I take a look at Security -> Rules I can found a lot of rules where integrations are missing or warnings are showing like This rule is attempting to query data from Elasticsearch indices listed in the "Index patterns" section of the rule definition, however no index matching: ["logs-endpoint.events.*"] was found. This warning will continue to appear until a matching index in created or this rule is disabled.

Is this anything we should care about?
From my understanding I can disable all rules with warnings as they wouldn't work anyway.

In Chapter 4 from your manual I could see at the screenshots the same "issues".
