Node statistics and performance testing


(andreasch) #1

I wrote a performance testing tool that retrieves node statistics
periodically and summarizes the statistics at the end of each performance
test run.

Is there a way to reset the statistics of a node preferably without
shutting down the node?

Thanks,
Andreas

Hi Andreas,

I don't think this is doable, but it may be an interesting feature to add.

If you want to reset the system for another performance run, wouldn't you
want to reset the node anyway to avoid warmed up cache issues? (Including
OS caches)

Restarting the nodes would be the ideal approach but the functionality to
restart a node using either the Java API or the REST API is currently
disabled:

Take a look at this script https://github.com/abronner/elasticsearch-monitoring
It dumps node stats into an index. Perhaps you could do some queries and math before and after your tests
