Overview

Tomcat connector internal thread pool JMX statistics are not exposed by default. In order to expose them, the JBoss instance must start with "org.apache.tomcat.util.ENABLE_MODELER" system property set to "true". This can be done in the .conf file corresponding to the mode JBoss is run in (standalone.conf or in domain.conf): 

JAVA_OPTS="${JAVA_OPTS} -Dorg.apache.tomcat.util.ENABLE_MODELER=true"

Alternatively, it can be specified in the <system-properties> section of the configuration file: 

<system-properties>
    ...
    <property name="org.apache.tomcat.util.ENABLE_MODELER" value="true"/>
    ...
</system-properties>

The system property will determine the Tomcat Http11Protocol or class AjpProtocol to expose the corresponding JIoEndpoit in JMX as "jboss.web:name=<protocol>-<bind-address>-<port>,type=ThreadPool". Example: "jboss.web:name=ajp-127.0.0.1-8009,type=ThreadPool".
