Class ClusterNode

java.lang.Object

com.alibaba.csp.sentinel.node.StatisticNode

com.alibaba.csp.sentinel.node.ClusterNode

All Implemented Interfaces:

Node

public class ClusterNode
extends StatisticNode

This class stores summary runtime statistics of the resource, including rt, thread count, qps and so on. Same resource shares the same ClusterNode globally, no matter in witch Context.

To distinguish invocation from different origin (declared in ContextUtil.enter(String name, String origin)), one ClusterNode holds an originCountMap, this map holds StatisticNode of different origin. Use getOriginNode(String) to get Node of the specific origin.
Note that 'origin' usually is Service Consumer's app name.

origin - The caller's name. It is declared in the ContextUtil.enter(String name, String origin).

Returns:

the Node of the specific origin.

getOriginCountMap

public HashMap<String,StatisticNode> getOriginCountMap()

trace

public void trace(Throwable throwable,
                  int count)

Add exception count only when throwable is not BlockException.isBlockException(Throwable)

Parameters:
