Description:
User Monitoring # Hits and Requests fails to update when Admin is on a different node than user.
A user who is logged onto different node than Admin, does not seem to be tracked by Monitoring, # of Hits stuck on 0, fails to update.
So, although Monitoring shows session of users on other nodes, not all of the data seems to be correctly tracked.

Steps to Reproduce:
In my testing I have two nodes in my cluster with the following properties set in my portal-ext.properties file

cluster.link.enabled=true
lucene.replicate.write=true
ehcache.cluster.link.replication.enabled=true

live.users.enabled=true

1. As my Admin user, I sign into my First Node 9080 and go to User Monitoring.
2. Then as my normal user, I sign into my Second Node 8080.
3. As my Admin user I see the user's session appear, although my user performs actions the # of Hits stays at 0, but I do see the time increase for Last Request.
However Requests and # of Hits do not update for users on different nodes than Admin user.

Results of Testing:
Expected Results: As Admin, able to track # of hits and Requests for all users even if they are on different node than Admin.
Actual Results: As Admin, # of hits and Requests of user fails to update for users on different node than Admin.
