Hey all. I've got a fleet managed agent which is, via the kubernetes integration (and others), creating data streams. I'm trying to understand what the size column is telling me and I don't seem to be able to find any documentation on it.

Is it total size of data in the index from that data set, or is that the size of the last document shipped?

Thanks!

Hi Sean,

Size here is referring to the `data_streams.store_size` from the [data stream stats API](https://www.elastic.co/guide/en/elasticsearch/reference/current/data-stream-stats-api.html#data-stream-stats-api-response-body).

> Total size of all shards for the data stream’s backing indices

Cool, thanks.

So essentially "all the data stored as shipped from that integration"?

Sounds about right. Maybe only if there is no other shipper writing to the same data stream.
