Hi ! With Elasticsearch 8.14 on Ubuntu, is it still required to set the max memory size to half the amount og available memory, or will elasticsearch calculate it automatically ?

If required to be set manually, where is the correct place to do it ? Traditionally i have set /etc/elasticsearch/jvm.options.d/jvm.options

How can i check that the correct amount is allocated ?

Hi there @elsgaard,

Here's the [8.14 docs](https://www.elastic.co/guide/en/elasticsearch/reference/8.14/important-settings.html#heap-size-settings) for heap size:

> By default, Elasticsearch automatically sets the JVM heap size based on a \> node’s [roles](https://www.elastic.co/guide/en/elasticsearch/reference/8.14/modules-node.html#node-roles) and total memory. We recommend the default sizing for most production environments.
> 
> If needed, you can override the default sizing by manually [setting the JVM heap size](https://www.elastic.co/guide/en/elasticsearch/reference/8.14/advanced-configuration.html#set-jvm-heap-size).
