Node exporter

Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.

The Node Exporter is disabled by default. You can enable it with the flags:

--set prometheus.server.nodeExporter.enabled=true
--set prometheus.serviceAccounts.nodeExporter.create=true

NVIDIA GPUs

NVIDIA GPU monitoring support can be explained in more detail in the Kubecost Docs: NVIDIA GPU Monitoring Configurations and on the Kubecost Blog: Monitoring NVIDIA GPU Usage in Kubernetes with Prometheus. Monitoring of NVIDIA GPUs requires DCGM Exporter. While all metrics exposed by DCGM Exporter are collected, the following metrics are the ones currently used by Kubecost:

Metric
