The tutorial on the Grafana Polystat Panel, specifically Part 2, expands on monitoring multiple Cassandra clusters within Kubernetes, utilizing a series of interconnected dashboards to provide an overview and detailed metrics. Starting with high-level rollups, the tutorial explains how to modify composites to represent the overall state of a cluster, integrating template variables for easier maintenance and customizing queries. It emphasizes creating a top-level view with the ability to drill down into more detailed dashboards, enhancing the visualization of metrics such as CPU usage. The guide highlights the potential for improvements like customizable tooltip widths, template variable usage in composites, and automatic composites to facilitate easier use of Polystat, while also encouraging users to share their dashboards on grafana.com.
