Hi,

Is there a way to force a heap dump with Elasticsearch? I have `OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-2ubuntu218.04)` running and unfortunately, `jmap` isn't part of that.

Thanks!

You can't get a heap dump directly out of Elasticsearch, no, you need to use `jmap`. If that's not included in your JDK then use a different JDK. The one that comes bundled with Elasticsearch is recommended, and includes `jmap`.
