I'm using opscenter free edition 4.0.2, with cassandra 2.0.3 on centos 6. The storage capacity widget on the landing page is showing no data at all. The storage-capacity call is returning:
{"free_gb": 0, "used_gb": 0, "reporting_nodes": 0}
However in the cluster ring view size is shown correctly.
Is there a way to fix this?
