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
GET _cat/thread_pool?v
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
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
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. |
