KubeLedger
What KubeLedger is
KubeLedger tracks Kubernetes CPU, memory and GPU use by namespace for usage accounting and cost allocation. Its accounting includes node overhead and resources that cannot be allocated, supporting chargeback and showback. It compares resource usage with requests over time to help identify over-provisioning and plan capacity. Built-in dashboards show hourly CPU and memory trends for seven days, daily accounting for 14 days and monthly accounting for 12 months. Charts and datasets can be exported as PNG, CSV or JSON, and integrations include a Prometheus exporter and an official Grafana dashboard. The site says KubeLedger keeps a full year of usage analytics with a fixed footprint under 100 MB. Installation is documented for Kubernetes and OpenShift using Kustomize or Helm, and the tool requires read-only access to Kubernetes API endpoints, including the Metrics API. An optional MCP server provides ten read-only tools for compatible assistants; it is disabled by default, lacks authentication at the tool layer and is exposed as a ClusterIP service in v1. Internal use is free, and the source code is available, but resale as a managed service is not allowed.
