[jira] [Created] (CASSANDRA-4962) JMX bean of StorageProxy is
sometimes invisible
Shotaro Kamio created CASSANDRA-4962:
----------------------------------------
Summary: JMX bean of StorageProxy is sometimes invisible
Key: CASSANDRA-4962
URL: https://issues.apache.org/jira/browse/CASSANDRA-4962
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.12, 1.0.7
Reporter: Shotaro Kamio
StorageProxy exposes info via JMX bean "org.apache.cassandra.db:type=StorageProxy". But that bean is sometimes invisible via jmxterm nor jconsole.
Seems like it becomes visible after data comes in.

Brandon Williams commented on CASSANDRA-4962:
---------------------------------------------
It's not invisible so much as it doesn't exist until it's instantiated. The same is true of a number of other mbeans, most notably HintedHandOffManager which will require two nodes to appear.

------------------------------------------
Is it possible to make them (at least StorageProxy) instantiated at startup?
We'd like to confirm some parameters via jmx right after maintenance of cassandra instance. But sending requests to cassandra is not what operators want to do in normal maintenance...
