Thread dump - where does it get logged?

Elastic Stack Elasticsearch
1

Hi,

I'm trying to do a thread dump using "sudo /etc/init.d/elasticsearch dump",
but all I get is this in /wrapper.log file:

STATUS | wrapper | 2012/05/22 16:26:40 | Dumping JVM state.

I also tried directly kill -QUITing the ES JVM process, but couldn't find
the dump anywhere. I didn't see it in /logs/.log
where I thought I'd see it.

Any pointers would be greatly appreciated.

Thanks,
Otis

Have you tried:

jstack -l PID_HERE

?

How why would I use something as simple as jstack when I can use kill
-QUIT? Just kidding - that worked, thanks!
