Getting Index Info from curl


When I do a verbose curl on my indexes this is what I'll see:

health status index               pri rep docs.count docs.deleted store.size
green  open   logstash-2016.02.22   5   1    3362748            0      2.9gb          1.4gb
green  open   logstash-2016.01.16   5   1    4808464            0      4.9gb          2.4gb

My question is, what is the difference between store.size and


Store.size is how much space in total the index is using up. This includes primary and replicas. is how much space the index takes up on just the primary shards.

You can see that the rep column shows 1 saying that each shard has 1 replica. Since a replica is a fully copy of the data, you are basically doubling the storage size.
