I think the issue with me trying to use the default agent folder instead of copying from opscenter node </p> http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2158 Wed, 13 Jun 2012 15:48:40 +0000 Anonymous 2158@http://www.datastax.com/support-forums/ <p>I turned of ssl following the documentation and everything seems to work fine </p> http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2157 Wed, 13 Jun 2012 15:48:32 +0000 nickmbailey 2157@http://www.datastax.com/support-forums/ <p>Disabling SSL would resolve your issue, however you do not need to disable it. If you do want to disable it, instructions are here: <a href="http://www.datastax.com/docs/opscenter/configure/configure_ssl#configuring-ssl" rel="nofollow">http://www.datastax.com/docs/opscenter/configure/configure_ssl#configuring-ssl</a></p> <p>It sounds like there was a problem with the manual install somehow. In each of your agents install directories you should see an 'ssl/' folder. The files in that folder (agentKeyStore*, opscenter*) should correspond to the files in a similar directory for the opscenter daemon install. Can you verify that the ssl files are matching? </p> http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2156 Wed, 13 Jun 2012 15:41:49 +0000 Anonymous 2156@http://www.datastax.com/support-forums/ <p>I did a manual install. I did not disable the ssl. just ran the setup for the agent.<br /> Do I need to disable ssl? If I need to, How would I do that?</p> <p>Thanks! </p> http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2154 Wed, 13 Jun 2012 15:37:10 +0000 nickmbailey 2154@http://www.datastax.com/support-forums/ <p>That error indicates a problem with SSL communcation between the agent and OpsCenter.</p> <p>How did you install the agents? Manually or using the UI?<br /> Did you disable SSL in the OpsCenter conf? </p> http://www.datastax.com/support-forums/topic/opscenter-agent-not-working-exception-in-logs#post-2152 Wed, 13 Jun 2012 15:10:14 +0000 Anonymous 2152@http://www.datastax.com/support-forums/ <p>I see the below exceptions in opscenter agent. The agent that is installed where opscenter was installed is working fine.
