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! </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts/page/2#post-8927 Tue, 05 Feb 2013 20:58:33 +0000 mbulman 8927@http://www.datastax.com/support-forums/ <p>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.</p> <p>Thanks </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts/page/2#post-8926 Tue, 05 Feb 2013 20:37:21 +0000 davidace47 8926@http://www.datastax.com/support-forums/ <p>Ok so apparently it seems something is wrong with my browser! I had other people go to <a href="http://&lt;opscenterd-host&gt;:8888" rel="nofollow">http://&lt;opscenterd-host&gt;:8888</a> 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.

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.</p> <p>First, make sure Cassandra is running properly on all of your nodes. You can verify this with 'nodetool ring' on one of the nodes.</p> <p>Now, assuming the machine you're running opscenterd on is 69.252.206.59: Verify that opscenterd is running, and that when you load <a href="http://&lt;opscenterd-host&gt;:8888" rel="nofollow">http://&lt;opscenterd-host&gt;:8888</a>, you can't see any nodes in the UI. &lt;opscenterd-host&gt; should be 69.252.206.59 or whatever the public IP of that machine is.</p> <p>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 <a href="http://&lt;opscenterd-host&gt;:8888/Dev_Cluster/nodes" rel="nofollow">http://&lt;opscenterd-host&gt;:8888/Dev_Cluster/nodes</a> </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts/page/2#post-8913 Mon, 04 Feb 2013 21:34:52 +0000 davidace47 8913@http://www.datastax.com/support-forums/ <p>Opscenter-2.1.2<br /> Cassandra 1.1 </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts#post-8912 Mon, 04 Feb 2013 21:18:55 +0000 mbulman 8912@http://www.datastax.com/support-forums/ <p>Can you tell me what version of OpsCenter and Cassandra you're running? </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts#post-8911 Mon, 04 Feb 2013 21:11:25 +0000 davidace47 8911@http://www.datastax.com/support-forums/ <p>I do not see any nodes when I open Opscenter matter of fact I get an error message:<br /> "Error<br /> Error loading cluster view: Unknown cluster partitioner"</p> <p>However prior to this I checked to see if Opscenter-agent was running (multiple instances) but it came back with nothing.<br /> [dayview@dayview-dev-ch2-02 ~] $ ps -ef | grep opscenter-agent<br /> dayview 12133 12105 0 21:02 pts/0 00:00:00 grep opscenter-agent<br /> Of course I restarted it before I got the "error" message I got that I showed above. Like you said it should be working right I would think and I'm really confused as to why it's not</p> <p>I must say that I'm really grateful for all your help on this. I really appreciate the time and effort.</p> <p>Thanks<br /> -David </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts#post-8904 Mon, 04 Feb 2013 15:49:20 +0000 mbulman 8904@http://www.datastax.com/support-forums/ <p>You do need to make sure the agent is running on all of your Cassandra nodes.</p> <p>The fact that it is still showing "0 of 0 agents connected" is very odd. Do you see any nodes when you open Cluster -&gt; Ring View? If not, it sounds like you may have multiple instances of opscenterd running. The output I had you send from the opscenterd API shows that it is seeing nodes, and I can't think of any reason the UI would not show them. </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts#post-8859 Fri, 01 Feb 2013 23:08:19 +0000 davidace47 8859@http://www.datastax.com/support-forums/ <p>[root@dayview-dev-ch2-02 conf]# ps -ef | grep opscenter-agent<br /> root 12301 20879 0 23:07 pts/1 00:00:00 grep opscenter-agent </p> http://www.datastax.com/support-forums/topic/stomp-connection-timeouts#post-8858 Fri, 01 Feb 2013 23:02:50 +0000 davidace47 8858@http://www.datastax.com/support-forums/ <p>Yeah.."0 of 0 agents connected" still.
