Is there a way to display the Lucene memory of Elasticsearch? I am using ES 2.4 on CentOS 6.9. I know it's found in /etc/sysconfig/elasticsearch, but is there a command I could use to check the lucene value?

Thanks

Hi,

I'm not sure in what you're interested exactly but you should check out the [node stats API](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/cluster-nodes-stats.html) and the [indices stats API](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/indices-stats.html).

Sorry for the delayed response.

`curl -XGET 'http://localhost:9200/_nodes/stats/jvm?pretty'`

This is exactly what I needed.

Thanks a bunch 😄
