### Question
- What do you want to know?
I want to develop a plugin to count the cost of
`org.apache.storm.spout.ISpout#nextTuple`.
My `instrumentation` define:
```java
private static final String ENHANCE_CLASS =
"org.apache.storm.spout.ISpout";
private static final String ENHANCE_METHOD = "nextTuple";
private static final String STORM_METHOD_INTERCEPT_CLASS =
"org.apache.skywalking.apm.plugin.storm.ISpoutInterceptor";
@Override
public ClassMatch enhanceClass() {
return byHierarchyMatch(new String[]{ENHANCE_CLASS});
}
// ……
}
```
My Plugin works well in Storm's `LocalCluster` model, but failed in Storm's
cluster model.
This is the cluster model's log:

Can you give me some advice to fix it?
