Currently, logback exposes an MBean to provide logging related controls via the inclusion of the following configuration:
<jmxConfigurator />

However, this always uses the platform mbean server:
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
(can be found in class JMXConfiguratorAction, line# 54).

I think it should be able to provide an option to use an MBeanServer with a specific domain, which is provided in the JMX spec.
The code needs to use the following:
List servers = MBeanServerFactory.findMBeanServer(agentId);
and then use the first one, possibly giving a warning if there are multiple.

This is crucial for our use-case, especially because we have separate MBeanServers in our web-app environment, and we need each application to use its own MBeanServer with a specific domain.

So, all in all, can we add an attribute of some sort, so that we can do the following:
<jmxConfigurator agentid="someMbeanServerId"/>

and if this is set, the code uses:
MBeanServer mbs = MBeanServerFactory.findMBeanServer(agentId).get(0);

and otherwise, it does whatever it used to do.
