Hello, I'm working on native Custom Score scripts and trying to profile my code --- but I do not know how to attach a profiler to my Elasticsearch instance. I tried using the YourKit profiler, and followed its instructions for enabling profiling both in a running JVM and in a new JVM with profiler support --- both to no avail. Is there a simple way of getting profiling information from Elasticsearch? Should I try a different profiler? Bear in mind that this comes from a Java beginner, so please be explicit! -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, maybe it helps, if you describe, what you tried already, so perhaps you are just missing a tiny step and others can jump in to help. You could also try jvisualvm (included in your JDK). Should work as easy as starting up elasticsearch via commandline, then starting jvisualvm and selecting the appropriate process - I also think, yourkit works the same, havent installed it at the moment to verify though. --Alex On Wed, Oct 2, 2013 at 11:26 AM, Maciej Kula [aggregaccount@gmail.com](mailto:aggregaccount@gmail.com)wrote: > Hello, > > I'm working on native Custom Score scripts and trying to profile my code > --- but I do not know how to attach a profiler to my Elasticsearch > instance.
