[jboss-user] [Management, JMX/JBoss] - Monitor alerts depending on jboss.web not deploying

[teknokrat]

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
