Thanks @kkewwei, I think a better approach would be to adjust the logger that this AbstractScopedSettings uses. See e.g.
for the pattern we usually use to create a per-index logger.
You will also need to supply a test that demonstrates that the messages logged now include the index name.

I think it'd be better to allow subclasses to provide their own logger rather than just a String, because I don't think we should be changing the behaviour for the logging of cluster-level settings.

Sorry @kkewwei, I still think this is not quite the right approach. I don't think applySettings should take a Logger, I think we should be using the AbstractScopedSettings#logger field. Something like the following.

Today we log changes to index settings like this:
updating [index.setting.blah] from [A] to [B]
The identity of the index whose settings were updated is conspicuously absent
from this message. This commit addresses this by adding the index name to these
messages.
Fixes #49818.
