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

threads -
(Optional, integer) Specifies the number of hot threads to provide
information for. Defaults to
