I don't know about web-console (it has not been working in the latest releases), but using jmx-console, in the jboss.jca:name=XXX,service=ManagedConnectionPool MBean (where XXX is the datasource name), you can find these attributes:
ConnectionCount - current number of connection to the database
InUseConnectionCount - the number of those connections that are active (in use by some app)
and various other counts.
