I am new to jboss and i am learning how the loadbalancer works in our application. There are two clusters and each server has two eap, from four eap's , two are used for bpm. From domain.xml of jboss eap 6.4 i have this

*

<mod-cluster-config advertise-socket="modcluster" connector="ajp">
                    <dynamic-load-provider>
                        <load-metric type="busyness"/>
                    </dynamic-load-provider>
</mod-cluster-config>

* and for jboss eap 7.0 for bpm i have 

<mod-cluster-config advertise-socket="modcluster" connector="ajp">
                    <dynamic-load-provider>
                        <load-metric type="cpu"/>
                    </dynamic-load-provider>
                </mod-cluster-config>

I am not able to get a lot of information on mod_cluster.

It would be really helpful if anyone would tell me how the mod_cluster is configured and how it works. Any helps or suggestions are welcome.

Thank you in advance.

<load-metric type="busyness"/> and <load-metric type="cpu"/> are nothing but load metric algorithm that is provided in Jboss for manipulating requests between load servers. Load Metric Algorithm

For your requirement , use the link as start up guide . It is self explanatory . Kindly modify the configuration to suit your need . Please add comments for any bottlenecks or errors.
