This API yields a breakdown of the hot threads on each selected node in the
|
|
|
|
|
cluster. Its endpoints are `/_nodes/hot_threads` and
|
|
|
|
|
`/_nodes/{nodes}/hot_threads`:

The first command gets the hot threads of all the nodes in the cluster. The
|
|
|
|
|
second command gets the hot threads of only `nodeId1` and `nodeId2`. Nodes can
|
|
|
|
|
be selected using <<cluster-nodes,node filters>>.

The output is plain text with a breakdown of each node's top hot threads. The

|

allowed parameters are:
