WSEJBStats (IBM WebSphere Application Server, Release 9.0)

```
public interface WSEJBStats
```
WebSphere Enterprise Java Beans stats interface. Enterprise Beans stats are structured as follows in the PMI tree:

<server>
|
|__Enterprise Beans+
  |
  |__<appName#ejb.jar>
    |
    |__Stateless Session Bean+
       |__<stateless_EJB1>
         |__Methods+
           |__<method_1>
    |
    |__Stateful Session Bean+
       |__<stateful_EJB1>
         |__Methods+
           |__<method_1>
    |
    |__Entity Bean+
       |__<entity_EJB1>
         |__Methods+
           |__<method_1>

+ indicates logical group

StatDescriptor is used to locate and access particular Stats in the PMI tree.
Example:
1. StatDescriptor that represents the Stateless session bean logical group: new StatDescriptor (new String[] {WSEJBStats.NAME, "appName#ejb.jar", "stateless_EJB1", WSEJBStats.EJB_STATELESS});
2. StatDescriptor that represents the a method in a Stateless session bean: new StatDescriptor (new String[] {WSEJBStats.NAME, "appName#ejb.jar", "stateless_EJB1", WSEJBStats.EJB_STATELESS, WSEJBStats.MethodStats.NAME, "method_1"});
