Comprehensive Kubernetes Autoscaling Monitoring with Prometheus and Grafana

The kubernetes-mixin is a popular resource for providing excellent dashboards and alerts for monitoring Kubernetes clusters. However, it lacks comprehensive support for autoscaling components such as Pod Disruption Budgets (PDB), Horizontal and Vertical Pod Autoscalers (HPA, VPA), Karpenter, and the Cluster Autoscaler. These essential components are commonly deployed in Kubernetes environments but do not have standardized, open-source monitoring solutions. This blog post aims to solve that by introducing the kubernetes-autoscaling-mixin - a set of Prometheus rules and Grafana dashboards for Kubernetes autoscaling.

Configuring VPA to Use Historical Metrics for Recommendations and Expose Them in Kube-state-metrics

The Vertical Pod Autoscaler (VPA) can manage both your pods’ resource requests but also recommend what the limits and requests for a pod should be. Recently, the kube-state-metrics project removed built-in support for VPA recommendation metrics, which made the VPA require additional configuration to be valuable. This blog post will cover how to configure the VPA to expose the recommendation metrics and how to visualize them in Grafana.
