The GPU Usage Monitor is an open-source project that deploys a fully integrated GPU observability stack for Kubernetes. Rather than requiring SRE and platform teams to assemble and configure individual components, the GPU Usage Monitor uses DCGM Exporter, kube-state-metrics, Prometheus, and Grafana into a single deployment, complete with pre-built dashboards designed specifically for GPU-accelerated workloads.
