    Fix Version/s: 8.0.0.Final
       Resolution: Done


Fixed. I have added trace logging to help debug this. There is a log of adv. messages coming in, we dont want this on a high level. Its on trace logging of mod_cluster package.

If you turn on logging for
{code}
            <logger category="org.jboss.modcluster">
                <level name="TRACE"/>
            </logger>
{code}
you will get:

{code}
13:33:16,694 TRACE [org.jboss.modcluster.advertise.impl.AdvertiseListenerImpl] (pool-1-thread-1) Advertise message digest verification passed for server 0c5d65e6-824d-4f84-9fe5-e6a47d5373da
{code}

or

{code}
13:35:09,671 TRACE [org.jboss.modcluster.advertise.impl.AdvertiseListenerImpl] (pool-1-thread-1) Advertise message digest verification failed for server a024799d-629d-4db6-9295-de3b84201d8d
{code}

> Run standalone server with -c standalone-ha.xml and mod_cluster configured on the same box for a simple load balancing test.  Modcluster is not able to detect the as7 instance without explicitly setting the Profiles > ModCluster > Proxies> ProxyList property in console to the ServerAdvertise value from httpd.conf.  There should be some sort of indication in the UI or in the server logs when Advertise functionality is not working or fails to work. 
> Additionally the documentation for modcluster setup and FAQ should be updated to include this note for those troubleshooting their modcluster setups.
