What are the options for a very small and nimble startup to do keep a cassandra cluster running well oiled. We are on AWS. We are interested in a monitoring tool and potentially also cluster management tools.
We are currently on apache cassandra 3.7. We were hoping the datastax opscenter would be it (It is free for startups our size). But, looks like it does not support cassandra versions greater than v2.1. It is pretty surprising considering cassandra v2.1 came out in 2014. We would consider downgrading to datastax cassandra 2.1 just to have robust monitoring tools. But, I am not sure if having opscenter offsets all the improvements that have been added to cassandra since 2.1. Sematext has a integrations for monitoring cassandra. Does anyone have good experience with it ? How much work would be involved to setup Ganglia or some such option for cassandra ? Thanks, Arun
