java 如何监控jms

1、	${ACTIVEMQ_HOME}/conf/activemq.xml 中的 broker 节点增加  useJmx="true" 属性
 
2、	${ACTIVEMQ_HOME}/conf/activemq.xml 中的 managementContext 节点修改成如下样子
 
	<managementContext>
	   <managementContext createConnector="true" connectorPort="11099" />
	</managementContext>	 
3.
vi 
/bin/activemq
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.200.129"
然后用jconsole
service:jmx:rmi:///jndi/rmi://192.168.200.128:11099/jmxrmi

如果不写第三步，会出现如下错误
