Actual Storage Load of a Cassandra node

Is there any way to get the actual data size stored on a node? The nodetool outputs afaik only the compressed data size. Thx!

Have you tried using nodetool cfstats <keyspace>? That should break it down on a per column family basis (for each column family in the specified keyspace). And it should give you more detail on space usage.
