# Embed Grafana panels in Markdown **(FREE)**
|
|
|
|
Grafana panels can be embedded in [GitLab Flavored Markdown](../../user/markdown.md). You can
|
|
embed Grafana panels using either:
|
|
|
|
- [Grafana-rendered images](#use-grafana-rendered-images).
|
|
- [Grafana API](#use-integration-with-grafana-api).
|
|
|
|
## Use Grafana-rendered images
|
|
|
|
You can embed live [Grafana](https://docs.gitlab.com/omnibus/settings/grafana.html) panels as a
|
|
[direct linked rendered image](https://grafana.com/docs/grafana/latest/reference/share_panel/#direct-link-rendered-image).
|
|
Your Grafana instance must:
|
|
|
|
- Be available to the target user, either as a public dashboard or on the same network.
|
|
- Have [Grafana Image Renderer](https://grafana.com/grafana/plugins/grafana-image-renderer/) installed.
|
|
|
|
To use Grafana-rendered images:
|
|
|
|
1. Go to the dashboard containing the panel in Grafana.
|
|
1. From the panel's menu, select **Share**.
|
|
1. Select the **Direct link rendered image** button, which provides the link.
|
|
1. Copy the link and add an image tag as [inline HTML](../../user/markdown.md#inline-html) in your
|
|
Markdown in the format `<img src="your_link"/>`. You can tweak the query parameters to meet your needs, such as removing the `&from=`
|
|
and `&to=` parameters to display a live panel.
|
|
|
|
## Use integration with Grafana API
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/31376) in GitLab 12.5.
|
|
|
|
Each project can support integration with one Grafana instance. This enables you to copy a link to a
|
|
panel in Grafana, then paste it into a GitLab Markdown field. The panel renders in the GitLab panel
|
|
format. To embed panels from a Grafana instance, the data source must be:
|
|
|
|
- A Prometheus instance.
|
|
- Proxyable, so the **HTTP > Access** setting for the Grafana data source should be set to
|
|
**Server (default)**.
|
|
|
|
### Set up Grafana integration
|
|
|
|
To set up the Grafana API in Grafana:
|
|
|
|
1. In Grafana, [generate an Admin-level API Token](https://grafana.com/docs/grafana/latest/http_api/auth/#create-api-token).
|
|
1. In your GitLab project, go to **Settings > Monitor** and expand the **Grafana authentication**
|
|
section.
|
|
1. To enable the integration, check the **Active** checkbox.
|
|
1. For **Grafana URL**, enter the base URL of the Grafana instance.
|
|
1. For **API Token**, enter the Admin API token you just generated.
|
|
1. Click **Save Changes**.
|
|
|
|
### Generate a link to a panel
|
|
|
|
To generate a link to a panel:
|
|
|
|
1. In Grafana, go to the dashboard you wish to embed a panel from.
|
|
1. In the upper-left corner of the page, select a specific value for each variable required for the
|
|
queries in the dashboard.
|
|
1. In Grafana click on a panel's title, then click **Share** to open the panel's sharing dialog to
|
|
the **Link** tab.
|
|
|
|
If you click the dashboard's share button instead, GitLab attempts to embed the first supported
|
|
panel on the dashboard (if available).
|
|
1. If your Prometheus queries use Grafana's custom template variables, ensure the
|
|
**Template variables** option is set to on. Only the Grafana global template variables
|
|
`$__interval`, `$__from`, and `$__to` are supported.
|
|
1. Set the **Current time range** option to on, to specify the time range of the panel. Otherwise,
|
|
the default range is the last 8 hours.
|
|
1. Select **Copy** to copy the URL to the clipboard.
|
|
1. In GitLab, paste the URL into a Markdown field and save. The panel takes a few moments to render.
|
|
|
|
See the following example of a rendered panel.
