Front matter

The source files of Grafana documentation use front matter to organize the content, order the project table of contents, and help users identify useful pages when searching or viewing the content in search engines or in social media, such as Twitter.

Use YAML for all front matter. Unless a front matter field is documented as supporting Markdown, do not include any special Markdown formatting, like italics, in that field.

Here’s a correctly built example:

description: Learn more about Grafana Mimir's microservices-based architecture.
    - oss
  - Mimir
  - microservices
  - architecture
menuTitle: Architecture
title: About Grafana Mimir architecture
weight: 100


The following headings describe what each front matter field does and provides guidelines for using it.


Use aliases to create redirects from the previous URL to the new URL when a page changes or moves.

When you rename or move files, you must create an alias with a reference to the previous URL path to create a redirect from the old URL to the new URL. In some cases, for example when you have deleted content or split a file into multiple topics, it may not be possible to create an alias for the moved content.


The following Markdown front matter snippet defines an alias /original-url/. You must incorporate it with any existing front matter.

  - /original-url/


The correct way to use aliases depends on whether the project is versioned or not.

Versioned projects

Aliases must be relative to avoid redirecting latest content to old versions.

If there is a page in the old documentation that has an alias that includes the version “latest”, and the page referred to by that alias doesn’t exist in the actual latest documentation, then Hugo creates a redirect at the page referred to by the alias.

That redirect redirects the user from latest documentation into the old documentation.

Aliases should include a YAML comment explaining the absolute URL path that the relative path redirects. This helps a reviewer confirm that your alias works correctly.

A YAML comment starts with a hash (#).

For example, the following Markdown front matter snippet, in the file, defines an alias to redirect /docs/grafana/<GRAFANA_VERSION/original-url/. The comment # /docs/grafana/<GRAFANA_VERSION>/original-url/ indicates the absolute URL path.

  - ./original-url/ # /docs/grafana/<GRAFANA_VERSION>/original-url/
Determine the relative alias

To determine the relative alias, you must first understand the meaning of the current directory (.) and parent directory (..) path elements when they’re used at the start of an alias.

For an alias in the page /docs/grafana/latest/alerting/manage-notifications/:

  • The current directory element (.) refers to the directory containing the current page, not the directory of the current page.

    In this example, this is the page /docs/grafana/latest/alerting/.

  • The parent directory element (..) refers to the parent directory of the current directory element.

    In this example, this is the page /docs/grafana/latest/.

In the following table:

  • From page: is the page that requires a redirect, for example because the page has been moved or no longer exists.
  • To page: is the page where readers are redirected to, for example the renamed page or where the content has been moved.
  • Relative alias: is the alias that must be added to the front matter of the file for To page to create the proper redirect.
/docs/grafana/latest/ # /docs/grafana/latest/alerting/
/docs/grafana/latest/alerting/silences/ # /docs/grafana/latest/alerting/silences/
/docs/grafana/latest/alerting/manage-notifications/create-silence/ # /docs/grafana/latest/alerting/manage-notifications/create-silence/
/docs/grafana/latest//docs/grafana/latest/alerting/manage-notifications/../ # /docs/grafana/latest/
/docs/grafana/latest/old-alerting//docs/grafana/latest/alerting/manage-notifications/../old-alerting/ # /docs/grafana/latest/old-alerting/
Use the docs/alias shortcode

You can use the docs/alias shortcode to determine the relative alias but you can’t use the shortcode in the front matter.

You must first use the shortcode in your source file and then copy the result from the page in the local web server into the front matter of the source file.

{{< docs/alias from="/docs/grafana/latest/old-alerting/" to="/docs/grafana/latest/alerting/manage-notifications/" >}}


/docs/grafana/latest/old-alerting//docs/grafana/latest/alerting/manage-notifications/../old-alerting/ # /docs/grafana/latest/old-alerting/

Other projects

  • Include an aliases entry for the current URL path.
  • Add an aliases entry to make it safer to move content around, as the redirect from old to new page location is already in place. Hugo doesn’t create a redirect .html file when the directory is already populated with content.
  • When a page is moved, update the aliases with the new URL path.

Test an alias

To test an alias results in the correct redirect, use your browser or a command-line tool for making HTTP requests.

Use the browser

  1. Start the documentation webserver with make docs.

  2. Browse to the URL of the page that should be redirected.

  3. Confirm that you are redirected to the desired page.

    For example, if you want the page to redirect to, browse to the following URL in the browser to confirm the redirect is working: http://localhost:3002/docs/grafana/latest/panels/working-with-panels/.

Use cURL

  1. Start the documentation webserver with make docs.

  2. In a separate terminal, make an HTTP GET request to the URL of the page that should be redirected. For example, to request the page localhost:3002/docs/grafana/latest/panels/working-with-panels/

    curl localhost:3002/docs/grafana/latest/panels/working-with-panels/

    The output is similar to the following:

    <!doctype html><html><head><script>const destination="http://localhost:3002/docs/grafana/latest/panels-visualizations/panel-editor-overview/";console.log(,document.head.innerHTML=`<meta http-equiv="refresh" content="0; url=${destination}${}"/>`</script><title>http://localhost:3002/docs/grafana/latest/panels-visualizations/panel-editor-overview/</title><link rel=canonical href=http://localhost:3002/docs/grafana/latest/panels-visualizations/panel-editor-overview/><meta name=robots content="noindex"><meta charset=utf-8><noscript><meta http-equiv=refresh content="0; url=http://localhost:3002/docs/grafana/latest/panels-visualizations/panel-editor-overview/"></noscript></head></html>
  3. Confirm that the value of the destination const in the <script> tag is the pretty URL for the page with the alias.


The canonical front matter sets the preferred URL for duplicate or very similar pages. Search engines use this information and only index the canonical URL.

The value of the canonical URL should be the full URL of the canonical page. For example,

For content reused in Grafana Cloud, prefer the open source documentation as the canonical page.


cascade is a map of front matter fields. The fields are passed down from the parent to the page descendants.

You can use cascade to define variables. For example:


Use the param shortcode in the topic body text wherever you need to insert the variable.


date describes the initial publish date of the page. Hugo produces XML page outputs for use by RSS feeds where users can be notified of updates. Customers use RSS feeds of release notes pages to be notified of new releases. Therefore, the date front matter is recommended for release note pages.

The value of the date field should be a full ISO 8601 timestamp. For example, date: "2023-04-24T00:00:00Z" is 12:00 AM, Apr 24 Coordinated Universal Time (UTC).

The date front matter also impacts menu ordering. Pages with more recent dates are lower in the menu.

Description (required)

Use description to provide the short description of the topic to search engines, including the search engine used in the Grafana documentation site. The description is also displayed on social media, such as Twitter, to provide a clue to users about the page contents.

Since the reader isn’t on the Grafana website, your description should include contextual information, such as the product name.

The number of characters vary by media, so make the description concise. Provide enough information to guide users to the content by describing what content the link leads to. Often, this doesn’t need to be original text. You can scan the first few paragraphs to pluck the appropriate terms or phrases into the description. If the description is too long, it’s truncated on social media.


When draft is set to true, this option prevents Hugo from rendering the content. Use the command-line flag --buildDrafts to generate content marked as draft: true.


The website uses keywords to generate links to related pages in the Related content sections. They don’t appear in the resulting HTML source for the page and don’t affect search engine optimization (SEO).

Ideally, use single terms as opposed to phrases.


Use the labels key to add one or more values that you want to appear before the topic title on the published page. Only certain labels are supported.

For labels.products, the supported values and the resulting published labels are as follows:

  • cloud: Grafana Cloud
  • enterprise: Enterprise
  • oss: Open source

For labels.stages, the supported values and the resulting published labels are as follows:

  • beta: Beta
  • alpha: Alpha
  • experimental: Experimental

Labels can be inherited through cascading front matter.

For versioned projects, the file resides in the website repository. For other projects, the file resides in the project’s repository.

If the default labels are incorrect for a page or directory of pages, update the labels. Also, if you are adding a new page, consider whether the default labels are appropriate. For each page, include a label in the labels.products sequence for every product that the page relates to.

For example, if a single page describes a feature available in Grafana Cloud and Grafana Enterprise, the source file front matter should include the following:

    - cloud
    - enterprise

For a directory of pages that describe a feature only available in Grafana Cloud, the branch bundle file front matter should include the following:

      - cloud

Use menuTitle to specify a different title in the sidebar navigation than in the title element. For example, if you want to abbreviate the topic title in the table of contents.

Don’t remove the verb from task topic titles. The verb helps the reader know that they’re navigating to a task topic before they follow the link.

It is OK to remove the verb from the menuTitle if it’s implied by the containing section. For example, the page ‘Install Grafana Alloy in a Docker container’ can be shortened to ‘Docker’ if it’s in a section named ‘Install’.


Use the refs front matter with ref URIs to link to different pages in reused content.

A partial front matter containing the refs field looks like:

    - pattern: <URL PATH PREFIX>
      destination: <FULL URL>
    - pattern: <URL PATH PREFIX>
      destination: <FULL URL>
  • <URL PATH PREFIX> - Enter the part of the page URL that represents the project in which the documentation is published.
  • destination - Enter the full URL of the destination page for that project including trailing slashes.

If the page’s URL matches the pattern <URL PATH PREFIX>, then Hugo uses destination as the link destination. If no pattern matches the current page, Hugo logs a build error.

The <FULL URL> destination has the same behavior as described in Link to pages


The following Markdown snippet demonstrates the refs front matter and link that uses a ref URI.

    - pattern: /docs/grafana/
    - pattern: /docs/grafana-cloud/

# Set up Alerting

## Before you begin

- Check which data sources are compatible with and supported by [Grafana Alerting](ref:grafana-alerting).

In the Grafana page, the link destination is Hugo replaces the version substitution syntax <GRAFANA_VERSION> with the version inferred from the current page.

In the page Grafana Cloud page, the link destination is

For more information, refer to Link from source content that’s used in multiple projects.

Review date

Use the review_date front matter to set the date you last reviewed a page for correctness.

Set the date using the YYYYY-MM-DD format, and separate the elements by using hyphens. For example, to set the last review date to June 6, 2024, use 2024-06-06.

The website includes the review date at the foot of the page’s content. You can see how this renders on the Writers’ Toolkit home page.


The slug front matter overrides the last segment of the URL path. It’s ineffective on files which are also known as section pages or branch bundles. For more information, refer to Slug.

You should prefer to update the filename instead of using the slug front matter because it makes it easier to find the correct source file for a URL.

Title (required)

Hugo uses the title to generate the sidebar table of contents if there is no menuTitle specified in the front matter. Your title should match your first heading for search engine optimization (SEO). The doc-validator linter enforces this.

The title becomes the document title element in the HTML. Often, browsers display this in the tab for the page.

Optimize the title for search engines.


By default, topics are displayed in alphabetical order by title.

Use weight to specify a different topic order within the left-hand sidebar on Smaller numbers place the topic earlier in the guide or section of the guide. Pages with the same weight are displayed in alphabetical order.

Use increments of 100 for content files. Doing so makes it easier for you to re-order existing topics when you add new topics. Weights are per directory.


There is additional front matter that you only need for tutorials. Tutorials should also include all the regular front matter.

Associated technologies

The associated_technologies front matter is a sequence of strings that refer to taxonomies in the website data directory. If you are a Grafana Labs employee, you can view the associated technologies in the website data directory.

The associated_technologies value is the filename without the file extension. For example, to refer to author defined in the mimir.yaml file, use mimir.

If you don’t set the associated_technologies front matter, grafana is the default.

The following YAML example demonstrates setting a single associated technology of mimir. You must incorporate it with the rest of your front matter.

  - mimir


The authors front matter is a sequence of strings that refer to author files defined in the website data directory. If you are a Grafana Labs employee, you can view and add authors to the website data directory.

The authors value is the filename without the file extension. For example, to refer to author defined in the grafana_labs.yaml file, use grafana_labs.

If no appropriate author file exists, grafana_labs is a good default.

The following YAML example demonstrates setting a single author of grafana_labs. You must incorporate it with the rest of your front matter.

  - grafana_labs


The summary front matter defines a short summary used on the tutorial’s card on

The following YAML example demonstrates summary front matter. You must incorporate it with the rest of your front matter.

summary: Use Telegraf to stream live metrics to Grafana.


The tags front matter is a sequence of strings displayed as tags under the author section on the tutorials page.

Typically, at least one of the tags is an expertise level. The expertise levels are:

  • Beginner
  • Intermediate
  • Advanced

The following YAML example demonstrates setting a single tag of the expertise level Beginner. You must incorporate it with the rest of your front matter.

  - Beginner
