-------------------------------
Summary: JmxTool should support querying all objects when
object-name is omitted
Key: KAFKA-2278
URL: https://issues.apache.org/jira/browse/KAFKA-2278
Project: Kafka
Issue Type: Improvement
Reporter: Dong Lin
Assignee: Dong Lin
One usecase of JmxTool is to allow user to query all existing objects and
attributes, such that the developer can quickly lookup the right object name
and attribute name in the output. Indeed, existing API of JmxTool allows user
to do this when object-name is not specified in argument.
However, current implementation of JmxTool doesn't support this operation due
to the way it is implemented. This is partly due to the fact that some JMX
object, such as java.lang:type=MemoryPool, doesn't have value for all its
attributes.
The patch submitted here will fix the problem.
