What are the Sense's columns meanings for GET _cat/indices?

I couldn't find anywhere what are the meanings of the columns at the Sense site for "GET _cat/indices" (indices endpoint).

If i'll try to guess -

yellow open .marvel-kibana 1 1 1 0 3.1kb 3.1kb
[status] [some other status?] [index name] [shards?] [?] [num of docs] [??] [size] [actual size?]

Thanks :slight_smile:

Add ?help at the end to see the help, and add ?v for column names.

Also this is an ES thing, not specific to Marvel, see https://www.elastic.co/guide/en/elasticsearch/reference/current/cat.html
