Server-side Configuration - Node Identity
6.1.5. Node Identity Like mod_jk and mod_proxy_balancer, mod_cluster identifies each node via a unique jvm route. By default, mod_cluster uses the following algorithm to assign the jvm route for a given node: Use the value from server.xml, , if defined. Generate a jvm route using the configured ???. The default implementation does the following: Use the value of the jboss.mod_cluster.jvmRoute system property, if defined. Generate a UUID. While UUIDs are ideal for production systems, in a development or testing environment, it is useful to know which node served a given request just by looking at the jvm route. In this case, you can utilize the org.jboss.modcluster.SimpleJvmRouteFactory. The factory generates jvm routes of the form: bind-address:port:engine-name
