Subject Re: monitor and alert tool for open source cassandra
Date Mon, 24 Sep 2018 22:59:21 GMT
Hi James,

Prometheus is the most common monitoring solution for K8s-managed

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:

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:
The project is approaching MVP status, and we would certainly appreciate
any feedback or contributions.
