$params['node_id'] = (array) Comma-separated list of node IDs or names to limit the returned information; use _local to return information from the node you're connecting to, leave empty to get information from all nodes. $params['ignore_idle_threads'] = (boolean) Don't show threads that are in known-idle places, such as waiting on a socket select or pulling from an empty task queue. (Default = true) $params['interval'] = (string) The interval for the second sampling of threads. $params['snapshots'] = (integer) Number of samples of thread stacktrace.
