Nice.. Good to see the community producing tools around the Cassandra product.
Few pieces of feedback *Kudos* 1. Glad that you are doing it 2. Looks great 3. Willing to try it out if you find this guy called "Free Time" for me :) *Criticism* 1. It mimics a lot of stack components that are out there.. Though I agree with you that the prometheus/grafana/etc stack is difficult to get running, I look at https://docs.scylladb.com/operating-scylla/monitoring/monitoring_stack/ and give them kudos for just making a simple tool to leverage what's there. Even DSE is now drinking the prometheus coolaid https://www.datastax.com/2018/12/improved-performance-diagnostics-with-datastax-metrics-collector 2. Given a choice of making something on my own (1), using a "stack" approach similar to Scylla (2), buying something that DSE produces (3), or buying AxonOps (4), the challenge for a practioner will be whether the cost offsets the effective pains of options 1 (more time),2( less time),3 (money) "It is not the critic who counts; not *the man* who points out how the strong *man* stumbles, or where the doer of deeds could have done them better. ... It is the man in the arena" - Teddy Roosevelt Keep play in the Arena and looking forward to updates!
