I have a cluster of elastic search, and it has a very large scale of data.  
Then I use kibana to show data, there is a .kibana index in elastic search.  
The .kibana index has only 10 documents, but it usually became red when I use kibana show.

What are the causes of becoming red for an small index, Please?
