   Opscenter-2.1.2
   Cassandra 1.1

   Ok, I'm a little stumped here, so let's take a step back. The first thing I want to figure it out is why you don't see any nodes, regardless of whether the agent is running and connected or not.

   First, make sure Cassandra is running properly on all of your nodes. You can verify this with 'nodetool ring' on one of the nodes.

   Now, assuming the machine you're running opscenterd on is 69.252.206.59: Verify that opscenterd is running, and that when you load http://<opscenterd-host>:8888, you can't see any nodes in the UI. <opscenterd-host> should be 69.252.206.59 or whatever the public IP of that machine is.

   If your Cassandra cluster is properly up and running, and you can't see any nodes in the OpsCenter UI, then re-send the output of http://<opscenterd-host>:8888/Dev_Cluster/nodes

   Top right of the page it says

   Active Nodes: 0 nodes
   Down Nodes: 0 nodes

   Dev_Cluster (Cassandra_ 0 of 0 agents connected

   Although where it says "Storage Capacity" it shows:
   1 0f 0 nodes

   I've only started one Opscenter-agent for now

   Ok so apparently it seems something is wrong with my browser! I had other people go to http://<opscenterd-host>:8888 and they all saw 3 nodes. Only mine seems to be showing 0 of 0 nodes so I'll have to have have that looked at. Thanks so much for your help good sir, it came in handy and I really learned a lot

   Aha. Glad you've figured something out. I'd love to hear what the issue ends up being, if you don't mind posting once you figure it out.

   Thanks

   Yes, actually it was very simple. Apparently my Firefox browser was calling cached version of the page and that's why it was still showing 0 nodes even after everything was configured and set up properly. All I had to do was clear the cache and it resolved the problem!
