kube-opex-analytics (literally Kubernetes Opex Analytics) is a Kubernetes usage accounting and analytics tool to help organizations track the resources being consumed by their Kubernetes clusters over time (hourly, daily, monthly). The purpose of kube-opex-analytics is to help prevent overpaying. Indeed, it provides insightful usage analytics metrics and charts, that engineering and financial teams can use as key indicators to take appropriate cost optimization decisions.

Key features:

  • Hourly consumption trends, daily and monthly accounting per namespace. This feature provides analytics metrics tracking both actual usage and requested capacities over time. Metrics are namespaced-based, collected every 5 minutes, consolidated on a hourly basis for trends, from which daily and monthly accounting is processed.
  • Accounting of non-allocatable capacities. At node and cluster levels, kube-opex-analytics tracks and consolidates the share of non-allocatable capacities and highlights them against usable capacities (i.e. capacities used by actual application workloads). In contrary to usable capacities, non-allocatable capacities are dedicated to Kubernetes operations (OS, kubelets, etc).
  • Cluster usage accounting and capacity planning. This feature makes it easy to account and visualize capacities consumed on a cluster, globally, instantly and over time.
  • Usage/requests efficiency. Based on hourly-consolidated trends, this functionality helps know how efficient resource requests set on Kubernetes workloads are, compared against the actual resource usage over time.
  • Cost allocation and charge back analytics: automatic processing and visualization of resource usage accounting per namespace on daily and monthly periods.
  • Insightful and extensible visualization. kube-opex-analytics enables built-in analytics dashboards, as well as a native Prometheus exporter that exposes its analytics metrics for third-party visualization tools like Grafana.

Multi-cluster Integration: kube-opex-analytics tracks the usage for a single Kubernetes cluster. For a centralized multi-Kubernetes usage analytics, use our Krossboard Kubernetes Operator product. Watch a demo video.
