Thanks, I'll take a look at that too. I also found that "nodetool info" gives some information as well. For instance, here's what one node reads:
Key Cache: size 104857584 (bytes), capacity 104857584 (bytes), 15085408 hits, 17336031 requests, 0.870 recent hit rate, 14400 save period in seconds. I'm guessing most people knew this, but I checked the 1.1 docs ( http://www.datastax.com/docs/1.1/references/nodetool#nodetool-info) and they don't mention that the "info" command shows key and row cache stats. Might be worth updating for others looking for this.
