Nodes hot_threads
editNodes hot_threads
editThis 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
:
GET /_nodes/hot_threads GET /_nodes/nodeId1,nodeId2/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 node filters.
The output is plain text with a breakdown of each node’s top hot threads. The allowed parameters are:
|
number of hot threads to provide, defaults to 3. |
|
the interval to do the second sampling of threads. Defaults to 500ms. |
|
The type to sample, defaults to cpu, but supports wait and block to see hot threads that are in wait or block state. |
|
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. |
