Get all Manager ObjectNames from all services and Hosts<\/p>\n

<jmx:query<\/p>\n

name=”Catalina:type=Manager,*<\/p>\n

resultproperty=”manager” \/><\/p>\n

 <\/p>\n

Now you can find the Session Manager at ${manager.[0..N].name} properties and access the result object counter with ${manager.length} property.<\/p>\n

 <\/p>\n

Example to get the Manager from servlet-examples application an bind all MBean properties<\/p>\n

 <\/p>\n

<jmx:query<\/p>\n

name=”Catalina:type=Manager,context=\/servlet-examples,host=localhost*”<\/p>\n

attributebinding=”true”<\/p>\n

resultproperty=”manager.servletExamples” \/><\/p>\n

 <\/p>\n

Now you can find the manager at ${manager.servletExamples.0.name} property and can access all properties from this manager with ${manager.servletExamples.0.[manager attribute names]}. The result object counter from MBeans is stored ad ${manager.length} property.<\/p>\n

Example to get all MBeans from a server and store inside an external XML property file<\/p>\n

 <\/p>\n

<project name=”jmx.query”<\/p>\n

xmlns:jmx=”antlib:org.apache.catalina.ant.jmx”<\/p>\n

default=”query-all” basedir=”.”><\/p>\n

<property name=”jmx.host” value=”localhost”\/><\/p>\n

<property name=”jmx.port” value=”8050″\/><\/p>\n

<property name=”jmx.username” value=”controlRole”\/><\/p>\n

<property name=”jmx.password” value=”tomcat”\/><\/p>\n

 <\/p>\n

<target name=”query-all” description=”Query all MBeans of a server”><\/p>\n

<!– Configure connection –><\/p>\n

<jmx:open<\/p>\n

host=”${jmx.host}”<\/p>\n

port=”${jmx.port}”<\/p>\n

ref=”jmx.server”<\/p>\n

username=”${jmx.username}”<\/p>\n

password=”${jmx.password}”\/><\/p>\n

 <\/p>\n

<!– Query MBean list –><\/p>\n

<jmx:query<\/p>\n

name=”*:*”<\/p>\n

resultproperty=”mbeans”<\/p>\n

attributebinding=”false”\/><\/p>\n

 <\/p>\n

<echoproperties<\/p>\n

destfile=”mbeans.properties”<\/p>\n

prefix=”mbeans.”<\/p>\n

format=”xml”\/><\/p>\n

 <\/p>\n

<!– Print results –><\/p>\n

<echo message=<\/p>\n

“Number of MBeans in server ${jmx.host}:${jmx.port} is ${mbeans.length}”\/><\/p>\n

<\/target><\/p>\n

<\/project><\/p>\n

Now you can find all MBeans inside the file mbeans.properties.<\/p>\n","protected":false},"excerpt":{"rendered":"
