Nodes hot threads API

edit

Nodes hot threads API

edit

Returns the hot threads on each selected node in the cluster.

Request

edit

GET /_nodes/hot_threads

GET /_nodes/<node_id>/hot_threads

Prerequisites

edit

If the Elasticsearch security features are enabled, you must have the monitor or manage cluster privilege to use this API.

Description

edit

This API yields a breakdown of the hot threads on each selected node in the cluster. The output is plain text with a breakdown of each node’s top hot threads.

Path parameters

edit

<node_id>: (Optional, string) Comma-separated list of node IDs or names used to limit returned information.

Query parameters

edit

ignore_idle_threads: (Optional, Boolean) If true, known idle threads (e.g. waiting in a socket select, or to get a task from an empty queue) are filtered out. Defaults to true.
interval: (Optional, time units) The interval to do the second sampling of threads. Defaults to 500ms.
snapshots: (Optional, integer) Number of samples of thread stacktrace. Defaults to 10.
threads: (Optional, integer) Specifies the number of hot threads to provide information for. Defaults to 3. If you are using this API for troubleshooting, set this parameter to a large number (e.g. 9999) to get information about all the threads in the system.
timeout: (Optional, time units) Specifies how long to wait for a response from each node. If omitted, waits forever.
type: (Optional, string) The type to sample. Available options are block, cpu, and wait. Defaults to cpu.

Examples

edit

resp = client.nodes.hot_threads()
print(resp)

resp1 = client.nodes.hot_threads(
    node_id="nodeId1,nodeId2",
)
print(resp1)

response = client.nodes.hot_threads
puts response

response = client.nodes.hot_threads(
  node_id: 'nodeId1,nodeId2'
)
puts response

const response = await client.nodes.hotThreads();
console.log(response);

const response1 = await client.nodes.hotThreads({
  node_id: "nodeId1,nodeId2",
});
console.log(response1);

GET /_nodes/hot_threads
GET /_nodes/nodeId1,nodeId2/hot_threads
