Hi James, Prometheus is the most common monitoring solution for K8s-managed applications.
There are a number of options to get Cassandra metrics into Prometheus. One of which, shameless plug, is something I've been working on for the past few months -- cassandra-exporter, a JVM agent that aims to be the easiest & fastest way to get Cassandra metrics into Prometheus. Check it out on GitHub: https://github.com/zegelin/cassandra-exporter cassandra-exporter is part of Instaclustrs current work-in-progress cassandra-operator for Kubernetes. If you're interested in running Cassandra on a K8s cluster and would like easy scale up/scale down, automatic Prometheus integration, automatic backups, etc, then an operator makes it a lot easier to manage. Check it out on GitHub: https://github.com/instaclustr/cassandra-operator The project is approaching MVP status, and we would certainly appreciate any feedback or contributions.
