There should be a log entry on startup pointing this out I believe. ---

Thanks. So no api for run time query? The cluster has been running for more than 1 year. ---

> [@linkerc](#): > > Thanks. > So no api for run time query? You can use the [`_nodes`](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-info.html) API for it. ```auto GET _nodes/jvm?pretty ``` This will return information about the _jvm_ on all nodes, one of the fields in the response is this: ```auto "using_compressed_ordinary_object_pointers": "true" ``` If you want to check just a specific node you can pass it in the API. ```auto GET _nodes/node-name-or-node-id/jvm?pretty ``` ---
