I wanted to test my es to find ideal cluster volume in my production level (the number of shards and their size etc)
I watched one video Quantitative Cluster Sizing
and decided to follow steps in the video
(Quantitative Cluster Sizing | Elastic) because many es docs recommend to follow this video (like How many shards should I have in my Elasticsearch cluster? | Elastic Blog)
But I cannot find docs about the way to get kibana dashboard latency per minute, events per second, data volume queried per minute, size of shards per minute throughputs/s and many other factors that was used in video
I found some meta data about cluster on stack monitoring tap in kibana but there are few data (only some info like indexing rate or document count) and window is too small to get specified value
should I use Rally? I don't know how to get these factors used for es test
