This repository contains the DCGM-Exporter project. It exposes GPU metrics exporter for Prometheus leveraging NVIDIA DCGM.
Official documentation for DCGM-Exporter can be found on docs.nvidia.com.
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:3.3.6-3.4.2-ubuntu22.04
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
...
DCGM_FI_DEV_SM_CLOCK{gpu="0", UUID="GPU-604ac76c-d9cf-fef3-62e9-d92044ab6e52"} 139
DCGM_FI_DEV_MEM_CLOCK{gpu="0", UUID="GPU-604ac76c-d9cf-fef3-62e9-d92044ab6e52"} 405
DCGM_FI_DEV_MEMORY_TEMP{gpu="0", UUID="GPU-604ac76c-d9cf-fef3-62e9-d92044ab6e52"} 9223372036854775794
...
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/dcgm-exporter/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/dcgm-exporter/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://127.0.0.1:8080/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).

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.
Exporter supports TLS and basic auth using exporter-toolkit. To use TLS and/or basic auth, users need to use --web-config-file
CLI flag as follows
dcgm-exporter --web-config-file=web-config.yaml
A sample web-config.yaml
file can be fetched from exporter-toolkit repository. The reference of the web-config.yaml
file can be consulted in the docs.
The DCGM-exporter can include High-Performance Computing (HPC) job information into its metric labels. To achieve this, HPC environment administrators must configure their HPC environment to generate files that map GPUs to HPC jobs.
These mapping files follow a specific format:
- Each file is named after a unique GPU ID (e.g., 0, 1, 2, etc.).
- Each line in the file contains JOB IDs that run on the corresponding GPU.
To enable GPU-to-job mapping on the DCGM-exporter side, users must run the DCGM-exporter with the --hpc-job-mapping-dir command-line parameter, pointing to a directory where the HPC cluster creates job mapping files. Or, users can set the environment variable DCGM_HPC_JOB_MAPPING_DIR to achieve the same result.
In order to build dcgm-exporter ensure you have the following:
git clone https://github.com/NVIDIA/dcgm-exporter.git
cd dcgm-exporter
make binary
sudo make install
...
dcgm-exporter &
curl localhost:9400/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/default-counters.csv
in the repository, which is copied on your system or container to /etc/dcgm-exporter/default-counters.csv
The layout and format of this file is as follows:
# 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 2 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/dcgm-api-field-ids.html
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
