Hi there! In a first progressive step, I managed to adapt a simple (yet effective) REST interface I've found at:
http://blogs.sun.com/jmxnetbeans/entry/restful_access_to_jmx_instrumentation The example was connecting to the first MBean server found on the virtual machine, so it was showing many JVM MBeans, but not the Cassandra ones. I added a JMXConnector articulation (connecting to the default 8080 port) to enable remote MBean browsing... with an awful implementation... HORRIBLE!... But it was just a simple test... It even supports reading of tabular, composite, collections, complex MBeans. Runs on it's own http server (in port 2021 in my example), this is a working URL which returns the requested data: http://localhost:2021/jmx/org.apache.cassandra.db:type=ColumnFamilyStores,name=Keyspace1,columnfamily=Standard2/MemtableDataSize So, that huge URI returns a single number!!! :P ---- Limitations so far: - TO-DO items: Set, Invoke and Notifications handling. - The "request-per-mbean-attribute" approach is a bit rough, the web client will be doing a request for every single magnitude being measured... the interface should have more commands to retrieve related sets of information, possibly JSON formatted. ----- Regards!
