I wrote cass_top, a poor man's version of OpsCenter, in bash (no dependencies.)
http://www.jebriggs.com/blog/2014/09/top-utility-for-cassandra-clusters-cass_top/ Actually, if it had node or cluster restart, it would do most of what the OpsCenter free version does. :) The features of cass_top are: - colorizes nodetool status output: UN nodes green, DN nodes red, other statuses blue - no extra firewall holes needed (agent-less and server-less), unlike OpsCenter - fast initial startup time (under 2 seconds), unlike OpsCenter - uses bash, so no programming environment needed - run it anywhere nodetool works - uses minimal screen real estate, so several rings can fit on one monitor - free (Apache 2). Please send me your comments and suggestions. The top-like infinite loop is actually a read loop, so adding a few more features like cfstats or flush would be easy.
