      I have created a monitor on the number of busy threads tomcat is using. When I restart jboss I get

      ObjectName: jboss.monitor:service=Busy_Thread_Count
 State: FAILED
 Reason: javax.management.InstanceNotFoundException: jboss.web:type=ThreadPool,name=http-0.0.0.0-80 is not registered.
 I Depend On:
 jboss.alerts:service=ConsoleAlertListener


      The problem appears that jboss tries to deploy the mbean before tomcat is ready

      The mbean is defined as 
      ?xml version="1.0" encoding="UTF-8"?>
<server>
<mbean code="org.jboss.monitor.ThresholdMonitor"
 name="jboss.monitor:service=Busy_Thread_Count">
 <attribute name="MonitorName">Busy Thread Count</attribute>
 <attribute name="ObservedObject">jboss.web:type=ThreadPool,name=http-0.0.0.0-80</attribute>
 <attribute name="ObservedAttribute">currentThreadsBusy</attribute>
 <depends-list optional-attribute-name="AlertListeners">
 <depends-list-element>jboss.alerts:service=ConsoleAlertListener </depends-list-element>
 </depends-list>
 <attribute name="Threshold">100</attribute>
 <attribute name="Period">10000</attribute>
 <attribute name="CompareTo">-1</attribute>
 <attribute name="Enabled">true</attribute>
</mbean>
</server>


      Clearly, there is no dependency on jboss.web defined. Will this bug be addressed?

      thank you
