In our usage of an earlier version of JBoss (5.1.0), we make use of the org.jboss.monitor.ThresholdMonitor bean

{{{
<!-- Generate a warning if there are less than two connections left -->
<mbean code="org.jboss.monitor.ThresholdMonitor" name="X:service=ThresholdMonitor,name=DefaultDS-ConnectionPool">
       
    <attribute name="MonitorName">DefaultDS-ConnectionPool</attribute>
 
    <depends optional-attribute-name="ObservedObject">jboss.jca:name=DefaultDS,service=ManagedConnectionPool</depends>
    <attribute name="ObservedAttribute">AvailableConnectionCount</attribute>
 
    <depends-list optional-attribute-name="AlertListeners">
        <depends-list-element>X:service=JmxNotificationListener</depends-list-element>
    </depends-list>
 
    <attribute name="Threshold">2</attribute>
    <attribute name="Period">60</attribute>
    <attribute name="CompareTo">1</attribute>
    <attribute name="Enabled">true</attribute>
   
</mbean>
}}}

The same monitor class is not provided in JBoss AS 7.1.1.Final. Does anybody know of an existing equivalent for AS7 ?
