What do these numbers mean in ElasticSearch head?

In the Overview tab of my ElasticSearch head it shows the following:

stock size: 2.2gb (2.2gb) docs: 1062049 (1598589)

Can someone tell me what the 2 docs numbers 1062049 and 1598589 mean?

The value without brackets shows us sum of sizes of primary shards.

The value inside brackets shows us sum of sizes of primary shards + sum of sizes of replica shards.

In your case, you've only 1 primary shard and 0 replica shards. So, it shows you index size 2.2 GB (2.2 GB).

Similar convention is followed for the document count.

I hope this helps.

The first number is num_docs, the second number is max_docs. Both are provided by the Index Status API

  • num_docs is simple: it is the number of documents living inside your index at this moment
  • max_docs is a bit more nebulous, I believe it is the max docs your index has seen before a merge removed the deleted docs. It also includes nested documents, which internally are a new doc but appear as a single doc to the end-user
