What is a good method for testing out different elastic search jvm parameters

(Tim) #1

I have a large Elastic Search cluster that I want to tune better. I have a few different things I want to try, including some different jvm parameters. What might be a good way to test the parameters that provides a valid confirmation if the jvm parameters are better.

I was thinking of bring up a new node that has the new jvm parameters and benchmarking the cpu/gc/speed against the other nodes. Would that be a valid test? I read that for other types of tuning like the Java version, you shouldn't run different versions in the same cluster. Is that true for jvm parameters as well?

We use rally to test these. I'm not really sure of the details beyond that though.
