# Nvidia Data Center GPU Manager (DCGM)


<img src="https://netdata.cloud/img/nvidia.svg" width="150"/>


Plugin: go.d.plugin
Module: dcgm

<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />

## Overview

This collector gathers NVIDIA GPU telemetry from a `dcgm-exporter` endpoint.
It supports all numeric fields exposed by the exporter and maps them into Netdata-native contexts.


It collects metrics by periodically scraping the exporter Prometheus endpoint over HTTP.


This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.


Nvidia Data Center GPU Manager (DCGM) can be monitored further using the following other integrations:

- [Nvidia GPU](/src/go/plugin/go.d/collector/nvidia_smi/integrations/nvidia_gpu.md)

### Default Behavior

#### Auto-Detection

This integration does not support auto-detection in v1.

#### Limits

The collector applies global and per-metric time series limits to prevent excessive cardinality.


#### Performance Impact

The impact depends on dcgm-exporter field selection and resulting series cardinality.

## Setup


You can configure the **dcgm** collector in two ways:

| Method                | Best for                                                                                 | How to                                                                                                                                 |

| [**UI**](#via-ui)     | Fast setup without editing files                                                         | Go to **Nodes → Configure this node → Collectors → Jobs**, search for **dcgm**, then click **+** to add a job. |
| [**File**](#via-file) | If you prefer configuring via file, or need to automate deployments (e.g., with Ansible) | Edit `go.d/dcgm.conf` and add a job.                                                                        |

:::important

UI configuration requires paid Netdata Cloud plan.

### Prerequisites

#### Run dcgm-exporter

Install DCGM and run `dcgm-exporter` so that a Prometheus endpoint is available (default `:9400/metrics`).

#### Configure exporter field list

The default exporter profile exposes a small subset of fields.
Use the Netdata recommended profile:
[`dcgm-exporter-netdata.csv`](https://github.com/netdata/netdata/blob/master/src/go/plugin/go.d/collector/dcgm/dcgm-exporter-netdata.csv)
(raw download: `https://raw.githubusercontent.com/netdata/netdata/master/src/go/plugin/go.d/collector/dcgm/dcgm-exporter-netdata.csv`).

The Netdata profile enables 127 fields by default and documents all remaining known DCGM fields as commented entries.
To customize beyond the baseline, uncomment the field you need and comment one currently enabled field.

Runtime validation artifact:
`src/go/plugin/go.d/collector/dcgm/runtime-validation-driver-590.48.01-dcgm-exporter-4.4.1-4.5.2.md`
and
`src/go/plugin/go.d/collector/dcgm/runtime-validation-driver-590.48.01-dcgm-exporter-4.4.1-4.5.2.json`

Validation is primarily version-scoped (NVIDIA driver + DCGM/DCGM-exporter versions), so treat it as a strong baseline rather than universal compatibility.

Example:
`dcgm-exporter -f /path/to/dcgm-exporter-netdata.csv`


#### Keep collection intervals aligned

Set Netdata `update_every` to the same value as dcgm-exporter collection interval (default 30 seconds).
Example exporter interval: `dcgm-exporter -c 30000` and Netdata `update_every: 30`.


#### Enable profiling capabilities (optional)

Profiling fields may require additional privileges/capabilities in your runtime environment.


### Configuration

#### Options

The following options can be defined globally: update_every, autodetection_retry.


<details open><summary>Config options</summary>



| Group | Option | Description | Default | Required |

| **Virtual Node** | vnode | Associate this job with a Virtual Node. |  | no |


</details>


#### via UI

Configure the **dcgm** collector from the Netdata web interface:

1. Go to **Nodes**.
2. Select the node **where you want the dcgm data-collection job to run** and click the :gear: (**Configure this node**). That node will run the data collection.
3. The **Collectors → Jobs** view opens by default.
4. In the Search box, type _dcgm_ (or scroll the list) to locate the **dcgm** collector.
5. Click the **+** next to the **dcgm** collector to add a new job.
6. Fill in the job fields, then click **Test** to verify the configuration and **Submit** to save.
    - **Test** runs the job with the provided settings and shows whether data can be collected.
    - If it fails, an error message appears with details (for example, connection refused, timeout, or command execution errors), so you can adjust and retest.


#### via File

The configuration file name for this integration is `go.d/dcgm.conf`.

The file format is YAML. Generally, the structure is:

```yaml
update_every: 1
autodetection_retry: 0
jobs:
  - name: some_name1
  - name: some_name2
```
You can edit the configuration file using the [`edit-config`](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.md#edit-configuration-files) script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.md#locate-your-config-directory).

```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/dcgm.conf
```

## Metrics

Metrics grouped by *scope*.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Metrics are grouped into static Netdata contexts. Contexts are created only when matching DCGM fields are present in the exporter output.



### Per gpu

These metrics refer to GPU device instances.

## Troubleshooting

### Debug Mode

**Important**: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.

To troubleshoot issues with the `dcgm` collector, run the `go.d.plugin` with the debug option enabled. The output
should give you clues as to why the collector isn't working.

- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.

  ```bash
  cd /usr/libexec/netdata/plugins.d/
  ```

- Switch to the `netdata` user.

  ```bash
  sudo -u netdata -s
  ```

- Run the `go.d.plugin` to debug the collector:

  ```bash
  ./go.d.plugin -d -m dcgm
  ```

  To debug a specific job:

  ```bash
  ./go.d.plugin -d -m dcgm -j jobName
  ```

### Getting Logs

If you're encountering problems with the `dcgm` collector, follow these steps to retrieve logs and identify potential issues:

- **Run the command** specific to your system (systemd, non-systemd, or Docker container).
- **Examine the output** for any warnings or error messages that might indicate issues.  These messages should provide clues about the root cause of the problem.

#### System with systemd

Use the following command to view logs generated since the last Netdata service restart:

```bash
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep dcgm
```

#### System without systemd

Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:

```bash
grep dcgm /var/log/netdata/collector.log
```

**Note**: This method shows logs from all restarts. Focus on the **latest entries** for troubleshooting current issues.

#### Docker Container

If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:

```bash
docker logs netdata 2>&1 | grep dcgm
```
