I just disabled SSL and I don't get that error any more. However I do get this message when I start the OpsCenter server. The Opsware agent is started on all nodes. Was wondering if there could be anything else that might be wrong:</p> <p>2012-12-04 21:41:16+0000 [Dev_Cluster] WARN: HTTP request <a href="http://69.252.206.62:61621/cluster/datacenter?node_ip=69.252.206.64" rel="nofollow">http://69.252.206.62:61621/cluster/datacenter?node_ip=69.252.206.64</a> failed: The http request to the agent timed out.

You can find more information here: <a href="http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2157" rel="nofollow">http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2157</a></p> <p>Let us know if that doesn't resolve your issue. </p> http://www.datastax.com/support-forums/topic/opscenter-agent-doesnt-start-and-connect#post-7788 Mon, 03 Dec 2012 22:16:09 +0000 davidace47 7788@http://www.datastax.com/support-forums/ <p>I have installed Opscenter on a linux server and wanted to install the agent on my Cassandra hosts. I followed the instructions given here but still can't get it to work. 69.252.116.59 is the IP of the server that has Opscenter installed on it.
