You can get the topology info from thrift's describe_ring. But you can not get host/gossip status through thrift. It does make sense as something to add. In the native protocol and with the fat client(storage proxy) you can hook into these events.
An example of this is here (fat client): https://github.com/zznate/intravert-ug/blob/master/src/main/java/org/usergrid/vx/server/IntravertClusterNotifier.java Basically implement IMigrationListener and you are made aware of metadata changing events. I believe a similar interface exists for topology changes.
