类 ClusterNode

java.lang.Object

com.alibaba.csp.sentinel.node.StatisticNode

com.alibaba.csp.sentinel.node.ClusterNode

所有已实现的接口:

Node, OccupySupport, DebugSupport

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 which 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 getOrCreateOriginNode(String) to get Node of the specific origin.
Note that 'origin' usually is Service Consumer's app name.

方法详细资料

getName

public String getName()

Get resource name of the resource node.

返回:

resource name

从以下版本开始:

1.7.0

getResourceType

public int getResourceType()

Get classification (type) of the resource.

返回:

resource type

从以下版本开始:

1.7.0

getOrCreateOriginNode

public Node getOrCreateOriginNode(String origin)

Get Node of the specific origin. Usually the origin is the Service Consumer's app name.

If the origin node for given origin is absent, then a new StatisticNode for the origin will be created and returned.

参数:

origin - The caller's name, which is designated in the parameter parameter ContextUtil.enter(String name, String origin).

返回:

the Node of the specific origin

getOriginCountMap

public Map<String,StatisticNode> getOriginCountMap()
