You can add, edit, or delete a cluster from OpsCenter and generate a PDF report about the cluster. OpsCenter Enterprise Edition 2.1.3 can monitor and administer Cassandra 1.2 as described in these procedures unless you enable virtual nodes. When you enable virtual nodes, OpsCenter chooses a single token for each node for operations, such as collecting metrics. Attempting to move nodes, rebalance nodes, and perform other tasks involving token ranges is not supported.
You must have a running and properly configured Cassandra cluster, as described in the documentation. OpsCenter 2.1.3 and later supports:

The report shows the version of OpsCenter, number of clusters and nodes being monitoring, gigabytes of storage used, name of the cluster, and information about nodes in the cluster. The node information includes:
You can save or print the PDF report.
