- gpu-fleet: cluster-wide admin view — inventory, capacity (total / allocated / free), per-node utilization and power, throttling, temperatures, XID errors. - gpu-tenants: per-namespace view — live allocation, utilization, tensor saturation, power, and 24h GPU-hours / kWh integrations for billing inputs. Register both under gpu/* in dashboards-infra.list so they ship as GrafanaDashboard CRs and fall under the bats cross-check introduced earlier on this branch. Update examples/README to spell out which DCGM counters each of the five gpu/* dashboards actually needs on top of the upstream default CSV — gpu-performance needs profiling and throttling counters, gpu-efficiency needs profiling, gpu-tenants needs only DCGM_FI_PROF_PIPE_TENSOR_ACTIVE for its tensor panel, and gpu-fleet and gpu-quotas work on the default counter set alone.

GPU operator — native pod workload on Talos (reference)
The files in this directory are not templates. They are reference
artifacts that document one working configuration for running GPU
workloads directly in pods on a Talos-based Cozystack cluster, together
with the DCGM metrics needed by the gpu/gpu-performance Grafana
dashboard.
The out-of-the-box values-talos.yaml for this package targets the
sandbox (VFIO passthrough to KubeVirt VMs) scenario. The files here
illustrate an alternative — running CUDA workloads in regular pods with
the NVIDIA device plugin — and the workarounds it currently requires on
Talos.
Files
values-native-talos.yaml— CozystackPackagevalues that disable sandbox workloads, enable the device plugin, pointhostPaths.driverInstallDirat the staging location used by the compat DaemonSet, and wire DCGM to the custom metrics ConfigMap.dcgm-custom-metrics.yaml—ConfigMapwith a DCGM metrics CSV that adds profiling, ECC, throttling and energy counters on top of the upstream defaults. The CSV is a superset needed for full coverage of thegpu/gpu-performancedashboard. Which parts are actually required depends on which dashboards you ship — see the table below.nvidia-driver-compat.yaml— DaemonSet that stageslibnvidia-ml.so.1andnvidia-smifrom the Talos glibc tree into a path where the NVIDIA GPU Operator validator expects them. See the "Why the compat DaemonSet exists" section below.
Why these are reference, not templates
Shipping these as first-class templates would silently impose assumptions that do not hold for every user:
- Whether the NVIDIA Talos system extension is installed on the nodes.
- Whether GPUs are exposed directly to pods or passed through to VMs.
- The exact path the installed driver ends up at (depends on the extension version and Talos release).
The sandbox-oriented values-talos.yaml remains the default. Operators
who want native pod GPU workloads can start from this directory and
adapt as needed.
Why the compat DaemonSet exists
The NVIDIA GPU Operator validator checks for libnvidia-ml.so.1 and
bin/nvidia-smi in the path given by hostPaths.driverInstallDir.
Talos installs them under /usr/local/glibc/usr/lib/ and
/usr/local/bin/, which the validator does not look at. Until upstream
addresses NVIDIA/gpu-operator#1687, the DaemonSet copies those
files into a directory the validator does inspect and creates the
.driver-ctr-ready flag file so the validator proceeds.
Dashboards and what DCGM metrics they need
Five GPU dashboards live under gpu/* in
packages/system/monitoring/dashboards-infra.list. All of them share
packages/system/monitoring-agents/alerts/gpu-recording.rules.yaml as
their source of aggregated series. The recording rules are safe to
ship on any cluster — they evaluate to empty series when DCGM is not
scraped, or when optional counters are missing.
What each dashboard needs on top of the upstream DCGM Exporter
default-counters.csv:
| Dashboard | Scope | Needs beyond defaults |
|---|---|---|
gpu-performance |
Per-node, per-GPU deep dive | DCGM_FI_PROF_PIPE_TENSOR_ACTIVE, DCGM_FI_PROF_GR_ENGINE_ACTIVE, DCGM_FI_DEV_POWER_VIOLATION, DCGM_FI_DEV_THERMAL_VIOLATION |
gpu-efficiency |
Per-workload util vs tensor active | DCGM_FI_PROF_PIPE_TENSOR_ACTIVE |
gpu-fleet |
Cluster-wide admin inventory | nothing (works on default counters) |
gpu-quotas |
Kube-quota vs live usage | nothing (kube-state-metrics + default counters) |
gpu-tenants |
Per-namespace tenant view | DCGM_FI_PROF_PIPE_TENSOR_ACTIVE for the tensor-saturation panel; other panels work on defaults |
The throttling counters (DCGM_FI_DEV_POWER_VIOLATION,
DCGM_FI_DEV_THERMAL_VIOLATION) are only required by gpu-performance.
The profiling counters (DCGM_FI_PROF_*) are required by
gpu-performance and gpu-efficiency, and unlock the tensor panel in
gpu-tenants. Everything else the recording rules consume —
utilization, FB used/free, power, temperature, energy — is already in
the default counter set.
Verification status
Pending verification on an updated GPU Operator release.
The minimum-CSV claims above are derived by cross-referencing
gpu-recording.rules.yamland each dashboard against the DCGM Exporterdefault-counters.csvfor the version pinned in the currently shippedgpu-operatorpackage. The package in this branch is not the latest GPU Operator release; once we move to a newer version, the claims must be re-checked because the upstream default set occasionally adds or removes counters between releases. Until then, treat the CSV indcgm-custom-metrics.yamlas a known-good superset rather than a minimal config.
