Hi,

I'm trying to calculate the indexing rate of my ES (version 8.8.0), and I've been using the API below to do that when I set `replica = 0`.

`GET <index_name>/_stats/indexing?filter_path=indices.*.total.indexing.index_total`

I would get the difference of the `index_total` values within a time period, and then divide by the time period to get the indexing rate.

When I set `replica = 1`, I get approximately 35-40% higher indexing rate than when no replica was set. Is this because the API included the documents indexed in the replica? If so, how do I get the indexing rate for only the primary shards then?

Thank you.
