CAT thread pool

Introduced 1.0

The CAT thread pool operation lists the active, queued, and rejected threads of different thread pools on each node.

Example

  1. GET _cat/thread_pool?v

copy

If you want to get information for more than one thread pool, separate the thread pool names with commas:

  1. GET _cat/thread_pool/thread_pool_name_1,thread_pool_name_2,thread_pool_name_3

copy

If you want to limit the information to a specific thread pool, add the thread pool name after your query:

  1. GET _cat/thread_pool/<thread_pool_name>?v

copy

Path and HTTP methods

  1. GET _cat/thread_pool
