I am running a 3 node cluster and basically I want to see how many writes per second I have to my index in ES. I know X-pack is good for this to give me monitoring functionality, but before I install it on my 3 node cluster, I want to just monitor these rates command line.

Is it possible command line, just to list how many writes I have to a particular index per second? I see there are many command for displaying cluster state,what can I issue just to to see Index Rate per second?

The command below almost gives me too much, all I want is a representation command line of what Monitoring in Kibana would give me, for Index rate p/s
curl -XGET 'localhost:9200/xyz/_stats?pretty'
