> My suggestion would be disable the `sampling` mechanism to stop creating
the TracingContext. What do you think?
This is a good way, our customized version provides another way, support
dynamic close all plugins, but dynamic switches can only be applied to a
limited number of plugins. like is,
```
public Object intercept(@This Object obj, @AllArguments Object[]
allArguments, @SuperCall Callable<?> zuper,
@Origin Method method) throws Throwable {
if (!DynamicPluginService.shouldTrace(targetClassName)) {
return zuper.call();
}
EnhancedInstance targetObject = (EnhancedInstance) obj;
MethodInterceptResult result = new MethodInterceptResult();
try {
interceptor.beforeMethod(targetObject, method, allArguments,
method.getParameterTypes(), result);
} catch (Throwable t) {
logger.error(t, "class[{}] before method[{}] intercept failure",
obj.getClass(), method.getName());
}
Object ret = null;
try {
if (!result.isContinue()) {
ret = result._ret();
} else {
ret = zuper.call();
}
} catch (Throwable t) {
try {
interceptor.handleMethodException(targetObject, method,
allArguments, method.getParameterTypes(), t);
} catch (Throwable t2) {
logger.error(t2, "class[{}] handle method[{}] exception
failure", obj.getClass(), method.getName());
}
throw t;
} finally {
try {
ret = interceptor.afterMethod(targetObject, method,
allArguments, method.getParameterTypes(), ret);
} catch (Throwable t) {
logger.error(t, "class[{}] after method[{}] intercept
failure", obj.getClass(), method.getName());
}
}
return ret;
}
```
