[ovirt-devel] [ANN] JMX control using CLI for ovirt-engine

[Roy Golan]

Hi all,

We can now have JMX control over the backend, from the command line, 
using ovirt authentication [1]

It's is now very easy to:

1. raise logging level to DEBUG
2. get threading info
3. get transaction stats
4. interact with whatever we exposed as JMX beans (like LockManager)
5. shutdown, redeploy context and so on...

$JBOSS_HOME/bin/jboss-cli.sh \
      --controller=127.0.0.1:8706 --connect --user=admin at internal \
/subsystem=logging/logger=org.ovirt.engine.core.bll:write-attribute(name=level,value=DEBUG)

See more examples in the commit message.

Currently only admin at internal would be allow to perform such actions. We 
may consider to extend that to a dedicated system role.
