Title Body

I just imported a lot of data in a 9 node Cassandra cluster and before I create a new ColumnFamily with even more data, I'd like to be able to determine how full my cluster currently is (in terms of memory usage). I'm not too sure what I need to look at. I don't want to import another 20-30GB of data and realize I should have added 5-6 more nodes. In short, I have no idea if I have too few/many nodes right now for what's in the cluster. Any help would be greatly appreciated :) $ nodetool -h 192.168.1.87 ring Address DC Rack Status State Load Owns Token 151236607520417094872610936636341427313 192.168.1.87 datacenter1 rack1 Up Normal 7.19 GB 11.11% 0 192.168.1.86 datacenter1 rack1 Up Normal 7.18 GB 11.11% 18904575940052136859076367079542678414 192.168.1.88 datacenter1 rack1 Up Normal 7.23 GB 11.11% 37809151880104273718152734159085356828 192.168.1.84 datacenter1 rack1 Up Normal 4.2 GB 11.11% 56713727820156410577229101238628035242 192.168.1.85 datacenter1 rack1 Up Normal 4.25 GB 11.11% 75618303760208547436305468318170713656 192.168.1.82 datacenter1 rack1 Up Normal 4.1 GB 11.11% 94522879700260684295381835397713392071 192.168.1.89 datacenter1 rack1 Up Normal 4.83 GB 11.11% 113427455640312821154458202477256070485 192.168.1.51 datacenter1 rack1 Up Normal 2.24 GB 11.11% 132332031580364958013534569556798748899 192.168.1.25 datacenter1 rack1 Up Normal 3.06 GB 11.11% 151236607520417094872610936636341427313 - # nodetool -h 192.168.1.87 cfstats Keyspace: stats
