Good morning,  
I'm trying to get the same information using the Java API that I can get using the curl command, "curl localhost:9200/\_cat/threadpool".

I'm using the TransportClient API to get the client connection to ElasticSearch.

When I use client.admin().cluster().threadpool(), and iterate over stats(), the only thread pool name that is populated with information is "generic", even though the curl command shows otherwise.

What is the correct API I should be using?

## Thank you.

You need to use `client().admin().cluster().prepareNodesStats().get()` which will give you an iterator over some NodeStats objects, and these objects have a `getThreadPool` property that you can use to get information about thread pools.

Thank you. You sent me in the right direction, but it missing one method call. The solution is:  
**client().admin().prepareNodesStats()._all()_.get()**;

Thank you! 😃
