I used the link here : [https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html#file-descriptors](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration.html#file-descriptors)

My query was the same as noted in the link above ie  
curl localhost:9200/\_nodes/stats/process?pretty

I substituted the localhost:9200 with the master node in the environment.

However, the response I get for each node only includes the open file descriptors under processes, and does NOT include the max file descriptors. Not sure what I am missing!

What version of ES are you using? I just tried with 2.3.5 and see both "open\_file\_descriptors" and "max\_file\_descriptors"

I am using 2.4.1. Did you query the ES master node (that's what I issue a query against)

Hm, could you gist up the complete response somewhere?

You could also try just the \_node/stats endpoint directly (e.g. no "process" filtering) although it shouldn't make a difference.

I did happen to query my master node, but it shouldn't matter: the API request will collect the node stats from all nodes in the cluster internally, regardless of which one you talk to.

What OS are you on? Perhaps it's not available on your platform?
