I've got an existing Cassandra cluster (Datastax Community v2.1, Linux). I've downloaded 2.0.10 on a separate box (Win) just to use Opscenter (v5). I add ('manage') the existing cluster by simply adding one or more of the IP addresses of the nodes, but get the following error messages:
Error creating cluster: c is undefined
Error getting basic OpsCenter information: Unable to load http://opscenter.datastax.com/latest-version?1411551302156 status: 0
After that, the page goes black with no visible content.
I can see that Opscenter has detected all the nodes in the opscenterd.log file. I can't see any errors or warnings (other than ignoring scheduled job...only with DSE) in the logfile either. It generates a conf file for my cluster, and the last thing I see in the log file is:
2014-09-24 10:57:11+0100 [] INFO: Starting to update agents' configuration
2014-09-24 10:57:11+0100 [preprod_group_a] INFO: OpsCenter starting up.

2014-09-24 10:57:11+0100 [preprod_group_a] INFO: Stopping repair servic
After that, nothing. Any ideas?
NB: if I install Opscenter on one of the Linux nodes, it runs fine - but we'd like to avoid this in a live environment
