public class MBeanConnector
extends MBeanHelper

Utility class to expose Coherence JMX MBeans via the Sun JMX reference implementation HtmlAdaptorServer or a JMX Remote JMXConnectorServer.

In order to use this class, the following system property may need to be set on the monitored cluster nodes (i.e. cache servers):

   -Dcoherence.management.remote=true
 

The following properties may be used for configuration of the monitoring node:

Monitoring properties

coherence.management	Specifies if a cluster node's JVM has an in-process MBeanServer and if this node allows management of other nodes' managed objects. Use all to specify management of this and all other remotely manageable cluster nodes
coherence.management.remote.host	The host that the JMX server will bind to. Default is localhost.
coherence.management.remote.registryport	The port used for the JMX RMI registry. Default is 9000.
coherence.management.remote.connectionport	The port used for the JMX RMI connection. Default is ephemeral.
coherence.management.remote.httpport	The port used for the HTTP connection. Default is 8888.

Since:

Coherence 3.3
