Re: 0.7.0 mx4j, get attribute
No idea. Is there an mx4j list you could try maybe? :) On Wed, Feb 2, 2011 at 10:40 AM, Chris Burroughs wrote: > I'm using 0.7.0 and experimenting with the new mx4j support. > > http://host:port/mbean?objectname=org.apache.cassandra.request%3Atype%3DReadStage > > Returns a nice pretty html page.

0.7.0 mx4j, get attribute
I'm using 0.7.0 and experimenting with the new mx4j support. http://host:port/mbean?objectname=org.apache.cassandra.request%3Atype%3DReadStage Returns a nice pretty html page. For purposes of monitoring I would like to get a single attribute as xml. The docs [1] decribe a "getattribute" endpoint. But I have been unable to get anything other than a blank response from that. mx4j does not seem to include any logging for troubleshooting. Example: http://host:port/getattribute?objectname=org.apache.cassandra.request%3atype%3dReadStage&attribute=PendingTasks returns 200 OK with no data. If anyone could point out what embarrassingly simple mistake I am making I would be much obliged. [1] http://mx4j.sourceforge.net/docs/ch05.html
