You may tweak the query parameters as required. For instance, removing the `&from=` and `&to=` parameters will give you a live chart. Here is example markup for a live chart from GitLab's public dashboard: + +```html +<img src="https://dashboards.gitlab.com/d/RZmbBr7mk/gitlab-triage?orgId=1&refresh=30s&var-env=gprd&var-environment=gprd&var-prometheus=prometheus-01-inf-gprd&var-prometheus_app=prometheus-app-01-inf-gprd&var-backend=All&var-type=All&var-stage=main&from=1580444107655&to=1580465707655"/> +``` + +This will render like so: + + + +## Embedding charts via integration with Grafana HTTP API + +> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/31376) in GitLab 12.5. + +Each project can support integration with one Grafana instance. This configuration allows a user to copy a link to a panel in Grafana, then paste it into a GitLab Markdown field. The chart will be rendered in the GitLab chart format. + +Prerequisites for embedding from a Grafana instance: + +1. The datasource must be a Prometheus instance. +1. The datasource must be proxyable, so the HTTP Access setting should be set to `Server`. + + + +## Setting up the Grafana integration + +1. [Generate an Admin-level API Token in Grafana.](https://grafana.com/docs/grafana/latest/http_api/auth/#create-api-token) +1. In your GitLab project, navigate to **Settings > Operations > Grafana Authentication**. +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**. + +## Generating a link to a chart + +1. In Grafana, navigate 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 chart. +  +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 panel instead, GitLab will attempt to embed the first supported panel on the dashboard (if available). +1. If your Prometheus queries use Grafana's custom template variables, ensure that the "Template variables" option is toggled to **On**. Of Grafana global template variables, only `$__interval`, `$__from`, and `$__to` are currently supported. Toggle **On** the "Current time range" option to specify the time range of the chart. Otherwise, the default range will be the last 8 hours. +  +1. Click **Copy** to copy the URL to the clipboard. +1. In GitLab, paste the URL into a Markdown field and save. The chart will take a few moments to render. +  |
