Hi Ernesto,
you may use a tool like JMeter to throw randomized queries and other
operations at an Elasticsearch instance. JMeter will take care of
counting requests per time and possibly also register other parameters
you may use for a more detailed evaluation. At the end of the day, the
total client count of queries that were processed in a given time frame
is important. Don't rely on Elasticsearch-internal counters that may
include other requests not visible to clients. The net performance
should be measured end-to-end, possibly not even on the REST service or
transport level, but at the respective front-end application (where one
page view may trigger multiple Elasticsearch requests).
Best regards,

Hello,
I don´t really know how to measure the number of requests per second
made to Elasticsearch cluster. I would like to know specifically the
number of search requests per second.
If I am not wrong, the stat "query_total" in "search" increases by the
number of shards being accessed in every search, so if it increases in
let´s say 25 units, that does not mean you had 25 _search requests but
ES has used 25 shards in total to answer to a single (or several)
_search request(s).
So, is it possible at all to know the number of _search requests per
second that your cluster receives? If not, is there any close approach
to this?
Thank you very much,
Ernesto
