Resolution:
You can turn on internal tracing by setting the appropriate values in the server.ini file. Specifically, you can set values for the variable:

com.tibco.infra.tools.trace.typesEnabled

Multiple values can be set in a comma separated list.

Example:  
com.tibco.infra.tools.trace.typesEnabled = ClientBridge,RemoteRepoProcess, CachedServer, NodeCache


ClientBridge - shows instance data messages being
                received and sent

RemoteRepoProcess - shows InstanceManagement  

CachedServer - shows status as server processes
                requests

NodeCache - shows actions in the server cache
