BusyConnectorsLoadMetric not working with Tomcat 6.0.13

[nichele]

Hi All,

i'm using mod-cluster 1.1.3 + tomcat 6.0.13.

This is the section i added in my server.xml:

  <Listener className="org.jboss.modcluster.catalina.ModClusterListener"

            advertise="false"

            proxyList="aaaaa:6666,bbbbb:6666,ccccc:6666"

            maxAttempts="3"

            nodeTimeout="600"

            workerTimeout="900"

            ping="60"

            stickySessionForce="true"

             />

As i have understood, mod-cluster should use BusyConnectorsLoadMetric with tomcat by default but what i'm seeing this is not true (i have 3 tomcat instances and on the slower one i have a large number of requests). Same result specifying in the listener definition:

loadMetricClass="org.jboss.modcluster.load.metric.impl.BusyConnectorsLoadMetric"

I added some debug info in ModclusterService.java (System.out.println("LBF: " + lbf); at line 493, method status) and in MBeanAttributeRatioLoadMetric  (System.out.println("Load: " + result + " (" + dividend + "/" + divisor + ")"); )

And in the catalina.out file i have:

Load: NaN (0.0/0.0)

LBF: 100

and this info never change.

Am I missing anything ? Any suggestion ?
