What snitch are you using? You may need to do some work on your topology file (or rackdc) to make sure you have the topology you want. Also, it is possible you may need to restart OpsCenter agents and/or your browser to see the nodes represented properly in OpsCenter.

When adding a new node, I saw that Opscenter saw the node in an unknown cluster. In the yaml, the cluster name is the same. So i have stopped the node and added it's ip address in the list of seeds. Now Opscenter sees my node. But nodetool status now sees it as UN, instead of UJ when it first started. One other mension is that even if I stop the node, remove it's ip from the list of seeds, Opscenter sees the node in the known clustre but nodetool sees it as UN. I am not sure what the implications of adding a node's ip in it's seed list are and I think that for the existing nodes I have might done the same. Eg. started with it's ip in the seed list but after removing it and having to restart the nodes for whatever reason, I did not see any changes. Is my cluster ok, or what do I need to do to bring the cluster to a good state?
