FINAL UPDATE: August 2021 - This repository has been deprecated.
This repository has been deprecated with the underlying components moved to their own repositories as noted below. The repository has also been archived; setting it to readonly.
The projects have been moved to their own repositories:
This repository will exist for a time to allow for migration to the new repositories.
NVIDIA GPU Monitoring Tools
This repository contains Golang bindings and DCGM-Exporter for gathering GPU telemetry in Kubernetes.
** NOTE: NVML Go bindings have moved to github.com. The NVML Go bindings in this repo are no longer maintained.
** July 2021 - Update #1: The DCGM Go bindings have moved to github.com. The DCGM bindings in this repo are no longer maintained and will eventually be removed.
** June 2021 - NOTICE: Some of the tools in this repository are graduating to their own repos. In the next few weeks both the DCGM Go bindings and the DCGM Exporter will be migrating to github.com/NVIDIA. This will allow for independent versioning, issues, MRs, etc. Efforts will be made to review the existing MRs and issues before the migration occurs.**
Bindings
Golang bindings are provided for the following two libraries:
- NVIDIA Management Library (NVML) is a C-based API for monitoring and managing NVIDIA GPU devices.
- NVIDIA Data Center GPU Manager (DCGM) is a set of tools for managing and monitoring NVIDIA GPUs in cluster environments. It's a low overhead tool suite that performs a variety of functions on each host system including active health monitoring, diagnostics, system validation, policies, power and clock management, group configuration and accounting.
You will also find samples for both of these bindings in this repository.
DCGM-Exporter
The repository also contains DCGM-Exporter. It exposes GPU metrics exporter for Prometheus leveraging NVIDIA DCGM.
Quickstart
To gather metrics on a GPU node, simply start the dcgm-exporter
container:
$ docker run -d --gpus all --rm -p 9400:9400 nvcr.io/nvidia/k8s/dcgm-exporter:2.0.13-2.1.2-ubuntu18.04
$ curl localhost:9400/metrics
# HELP DCGM_FI_DEV_SM_CLOCK SM clock frequency (in MHz).
# TYPE DCGM_FI_DEV_SM_CLOCK gauge
# HELP DCGM_FI_DEV_MEM_CLOCK Memory clock frequency (in MHz).
# TYPE DCGM_FI_DEV_MEM_CLOCK gauge
# HELP DCGM_FI_DEV_MEMORY_TEMP Memory temperature (in C).
# TYPE DCGM_FI_DEV_MEMORY_TEMP gauge
...

Quickstart on Kubernetes
Note: Consider using the NVIDIA GPU Operator rather than DCGM-Exporter directly.
Ensure you have already setup your cluster with the default runtime as NVIDIA.
The recommended way to install DCGM-Exporter is to use the Helm chart:
$ helm repo add gpu-helm-charts \
https://nvidia.github.io/gpu-monitoring-tools/helm-charts
Update the repo:
$ helm repo update
And install the chart:
$ helm install \
--generate-name \
gpu-helm-charts/dcgm-exporter
Once the dcgm-exporter
pod is deployed, you can use port forwarding to obtain metrics quickly:
$ kubectl create -f https://raw.githubusercontent.com/NVIDIA/gpu-monitoring-tools/master/dcgm-exporter.yaml
# Let's get the output of a random pod:
$ NAME=$(kubectl get pods -l "app.kubernetes.io/name=dcgm-exporter" \
-o "jsonpath={ .items[0].metadata.name}")
$ kubectl port-forward $NAME 8080:9400 &
$ curl -sL http://127.0.01:8080/metrics
# HELP DCGM_FI_DEV_SM_CLOCK SM clock frequency (in MHz).
# TYPE DCGM_FI_DEV_SM_CLOCK gauge
# HELP DCGM_FI_DEV_MEM_CLOCK Memory clock frequency (in MHz).
# TYPE DCGM_FI_DEV_MEM_CLOCK gauge
# HELP DCGM_FI_DEV_MEMORY_TEMP Memory temperature (in C).
# TYPE DCGM_FI_DEV_MEMORY_TEMP gauge
...

To integrate DCGM-Exporter with Prometheus and Grafana, see the full instructions in the user guide.
dcgm-exporter
is deployed as part of the GPU Operator. To get started with integrating with Prometheus, check the Operator user guide.
Building from Source
dcgm-exporter
is actually fairly straightforward to build and use.
Ensure you have the following:
$ git clone https://github.com/NVIDIA/gpu-monitoring-tools.git
$ cd gpu-monitoring-tools
$ make binary
$ sudo make install
...
$ dcgm-exporter &
$ curl localhost:9400/metrics
# HELP DCGM_FI_DEV_SM_CLOCK SM clock frequency (in MHz).
# TYPE DCGM_FI_DEV_SM_CLOCK gauge
# HELP DCGM_FI_DEV_MEM_CLOCK Memory clock frequency (in MHz).
# TYPE DCGM_FI_DEV_MEM_CLOCK gauge
# HELP DCGM_FI_DEV_MEMORY_TEMP Memory temperature (in C).
# TYPE DCGM_FI_DEV_MEMORY_TEMP gauge

Changing Metrics
With dcgm-exporter
you can configure which fields are collected by specifying a custom CSV file.
You will find the default CSV file under etc/dcgm-exporter/default-counters.csv
in the repository, which is copied on your system or container at
/etc/dcgm-exporter/default-counters.csv
The format of this file is pretty straightforward:
# Format,,
# If line starts with a '#' it is considered a comment,,
# DCGM FIELD, Prometheus metric type, help message
# Clocks,,
DCGM_FI_DEV_SM_CLOCK, gauge, SM clock frequency (in MHz).
DCGM_FI_DEV_MEM_CLOCK, gauge, Memory clock frequency (in MHz).
A custom csv file can be specified using the -f
option or --collectors
as follows:
$ dcgm-exporter -f /tmp/custom-collectors.csv
Notes:
- Always make sure your entries have 3 commas (',')
- The complete list of counters that can be collected can be found on the DCGM API reference manual: https://docs.nvidia.com/datacenter/dcgm/latest/dcgm-api/group__dcgmFieldIdentifiers.html
What about a Grafana Dashboard?
You can find the official NVIDIA DCGM-Exporter dashboard here: https://grafana.com/grafana/dashboards/12239
You will also find the json
file on this repo under grafana/dcgm-exporter-dashboard.json
