Logstash non-heap memory

Elastic Stack Logstash
1

I run Logstash in a docker container (using the official image).

I assigned 10GB of memory to the container.

How much of these 10GB should be heap and how much non-heap?

50%-50% like Elasticsearch? 90%-10%?

@cciaccio, in most circumstances, Logstash does not benefit from leaving significant RAM free for the filesystem cache as Elasticsearch does, so I would suggest starting at 90% for the heap and see how that works for your workload.

Thanks @danhermann
