CAT thread pool

Introduced 1.0 {: .label .label-purple }

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

Example

GET _cat/thread_pool?v

{% include copy-curl.html %}

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

GET _cat/thread_pool/thread_pool_name_1,thread_pool_name_2,thread_pool_name_3

{% include copy-curl.html %}

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

GET _cat/thread_pool/<thread_pool_name>?v

{% include copy-curl.html %}

Path and HTTP methods

GET _cat/thread_pool

URL parameters

All CAT thread pool URL parameters are optional.

In addition to the common URL parameters, you can specify the following parameter:

Parameter	Type	Description
local	Boolean	Whether to return information from the local node only instead of from the cluster_manager node. Default is false.
cluster_manager_timeout	Time	The amount of time to wait for a connection to the cluster_manager node. Default is 30 seconds.
