We built a Cassandra metrics tracking and monitoring project https://github.com/smartcat-labs/cassandra-diagnostics that will pump said metrics into your monitoring system; we are working on adding new features (maybe repair and restart) but I've also always heard good things about Spotify's Reaper https://github.com/spotify/cassandra-reaper re repairs
