OpsCenter performance metrics¶
In the Performance area of OpsCenter, you monitor a number of performance metrics about a Cassandra cluster. Real-time and historical performance metrics are available at different granularities: cluster-wide, per node, or per column family. OpsCenter 2.1 and later has been optimized to handle thousands of column families efficiently.
