I'm getting authentication errors when starting the opscenter agents on each of my cassandra (v1.2.5) nodes:

INFO [main] 2014-07-23 12:18:03,880 Starting Stomp

I've manually installed these agents from tarballs. I've not yet found clear documentation on how the Opscenter agent, server & cassandra node initialise with one another it's not clear to me what is wrong. Can someone point me to what configuration I need in order to get this to work?

You'll want to specify credentials for Cassandra via the Edit Cluster form in the OpsCenter UI. These will automatically be sent to the agent which will use them to connect to the local node.

  • Correct; assuming you are already running a SSH-server on the node. Be also sure you installed the sysstat packages as this is needed to get it fully working. – Melroy van den Berg Aug 08 '14 at 20:58
