All of our documentation is written in Markdown.
Use semantic linefeeds. Separating each sentence with a new line makes it easy to parse diffs with the human eye.
Diff without semantic linefeeds:
-Data is taking off. This data is time series. You need a database that specializes in time series. You should check out InfluxDB.

+You need InfluxDB.Use only h2-h6 headings in markdown content.
h1 headings act as the page title and are populated automatically from the title frontmatter.
h2-h6 headings act as section headings.
Save images using the following naming format: project/version-context-description.png.
For example, influxdb/2-0-visualizations-line-graph.png or influxdb/2-0-tasks-add-new.png.
Specify a version other than 2.0 only if the image is specific to that version.
Every documentation page includes frontmatter which specifies information about the page. Frontmatter populates variables in page templates and the site's navigation menu.
title: # Title of the page used in the page's h1
seotitle: # Page title used in the html <head> title and used in search engine results
list_title: # Title used in article lists generated using the {{< children >}} shortcode
description: # Page description displayed in search engine results
menu:
influxdb_2_0:
name: # Article name that only appears in the left nav
parent: # Specifies a parent group and nests navigation items
weight: # Determines sort order in both the nav tree and in article lists
draft: # If true, will not render page on build
product/v2.x/tags: # Tags specific to each version (replace product and .x" with the appropriate product and minor version )
related: # Creates links to specific internal and external content at the bottom of the page

list_image: # Image included with article descriptions in children type="articles" shortcode
list_note: # Used in children shortcode type="list" to add a small note next to listed links
list_code_example: # Code example included with article descriptions in children type="articles" shortcode
list_query_example: # Code examples included with article descriptions in children type="articles" shortcode,
# References to examples in data/query_examples
canonical: # Path to canonical page, overrides auto-gen'd canonical URL
v2: # Path to v2 equivalent page
prepend: # Prepend markdown content to an article (especially powerful with cascade)
block: # (Optional) Wrap content in a block style (note, warn, cloud)
content: # Content to prepend to article
append: # Append markdown content to an article (especially powerful with cascade)
block: # (Optional) Wrap content in a block style (note, warn, cloud)
content: # Content to append to articleThe title frontmatter populates each page's h1 header.
It shouldn't be overly long, but should set the context for users coming from outside sources.
The seotitle frontmatter populates each page's HTML title attribute.
Search engines use this in search results (not the page's h1) and therefore it should be keyword optimized.
The list_title frontmatter determines an article title when in a list generated
by the {{< children >}} shortcode.
The name attribute under the menu frontmatter determines the text used in each page's link in the site navigation.
It should be short and assume the context of its parent if it has one.
To ensure pages are sorted both by weight and their depth in the directory structure, pages should be weighted in "levels." All top level pages are weighted 1-99. The next level is 101-199. Then 201-299 and so on.
Note: _index.md files should be weighted one level up from the other .md files in the same directory.
Use the related frontmatter to include links to specific articles at the bottom of an article.
- If the page exists inside of this documentation, just include the path to the page. It will automatically detect the title of the page.
- If the page exists inside of this documentation, but you want to customize the link text, include the path to the page followed by a comma, and then the custom link text. The path and custom text must be in that order and separated by a comma and a space.
- If the page exists outside of this documentation, include the full URL and a title for the link. The link and title must be in that order and separated by a comma and a space.

- /v2.0/write-data/quick-start
- /v2.0/write-data/quick-start, This is custom text for an internal link
- https://influxdata.com, This is an external linkSearch engines use canonical URLs to accurately rank pages with similar or identical content.
The canonical HTML meta tag identifies which page should be used as the source of truth.
By default, canonical URLs are automatically generated for each page in the InfluxData documentation using the latest version of the current product and the current path.
Use the canonical frontmatter to override the auto-generated canonical URL.
Note: The canonical frontmatter supports the {{< latest >}} shortcode.
canonical: /path/to/canonical/doc/
# OR
canonical: /{{< latest "influxdb" "v2" >}}/path/to/canonical/doc/To display a notice on a 1.x page that links to an equivalent 2.0 page, add the following frontmatter to the 1.x page:
v2: /influxdb/v2.0/get-started/Use the prepend and append frontmatter to add content to the top or bottom of a page.
Each has the following fields:
- block: (Optional) block style to wrap content in (note, warn, cloud, or enterprise)
- content: (Required) markdown content to add.
append:
block: note

#### This is example markdown content
This is just an example note block that gets appended to the article.Use this frontmatter with cascade to add the same content to all children pages as well.
cascade:
append:
block: note
content: |
#### This is example markdown content
This is just an example note block that gets appended to the article.To automatically apply frontmatter to a page and all of its children, use the
cascade frontmatter
built in into Hugo.
title: Example page
description: Example description
cascade:
layout: custom-layoutcascade applies the frontmatter to all children unless the child already includes
those frontmatter keys. Frontmatter defined on the page overrides frontmatter
"cascaded" from a parent.
Shortcodes are available for formatting notes and warnings in each article:
{{% note %}}
Insert note markdown content here.
{{% /note %}}
{{% warn %}}
Insert warning markdown content here.
{{% /warn %}}For sections content that relate specifically to InfluxDB Enterprise, use the {{% enterprise %}} shortcode.
{{% enterprise %}}
Insert enterprise-specific markdown content here.
{{% /enterprise %}}The name used to refer to InfluxData's enterprise offering is subject to change.
To facilitate easy updates in the future, use the enterprise-name shortcode
when referencing the enterprise product.
This shortcode accepts a "short" parameter which uses the "short-name".
This is content that references {{< enterprise-name >}}.
This is content that references {{< enterprise-name "short" >}}.
Product names are stored in data/products.yml.
References to InfluxDB Enterprise are often accompanied with a link to a page where
visitors can get more information about the Enterprise offering.
This link is subject to change.
Use the enterprise-link shortcode when including links to more information about
InfluxDB Enterprise.
Find more info [here][{{< enterprise-link >}}]
For sections of content that relate specifically to InfluxDB Cloud, use the {{% cloud %}} shortcode.
{{% cloud %}}
Insert cloud-specific markdown content here.
{{% /cloud %}}The name used to refer to InfluxData's cloud offering is subject to change.
To facilitate easy updates in the future, use the cloud-name short-code when
referencing the cloud product.
This shortcode accepts a "short" parameter which uses the "short-name".
This is content that references {{< cloud-name >}}.
This is content that references {{< cloud-name "short" >}}.
Product names are stored in data/products.yml.
References to InfluxDB Cloud are often accompanied with a link to a page where
visitors can get more information.
This link is subject to change.
Use the cloud-link shortcode when including links to more information about
InfluxDB Cloud.
Find more info [here][{{< cloud-link >}}]
Each of the InfluxData projects have different "latest" versions.
Use the {{< latest >}} shortcode to populate link paths with the latest version
for the specified project.
[Link to latest Telegraf](/{{< latest "telegraf" >}}/path/to/doc/)To constrain the latest link to a major version, include a second argument with the major version:
[Link to latest InfluxDB 1.x](/{{< latest "influxdb" "v1" >}}/path/to/doc/)]{{< latest "telegraf" >}} is replaced with telegraf/v1.15 (or whatever the latest version is).
{{< latest "influxdb" "v1" >}} is replaced with influxdb/v1.8 (or whatever the latest v1.x version is).
Use the following for project names:
- influxdb
- telegraf
- chronograf
- kapacitor
- enterprise_influxdb
Note: Include a leading slash before the latest shortcode and a trailing slash after in all link paths:
/{{< latest "telegraf" >}}/Use the {{< latest-patch >}} shortcode to add the latest patch version of a product.
By default, this shortcode parses the product and minor version from the URL.
To specify a specific product and minor version, use the product and version arguments.
Easier to maintain being you update the version number in the data/products.yml file instead of updating individual links and code examples.
{{< latest-patch >}}
{{< latest-patch product="telegraf" >}}
{{< latest-patch product="chronograf" version="1.7" >}}Use the {{< latest-cli >}} shortcode to add the latest version of the influx
CLI supported by the minor version of InfluxDB.
By default, this shortcode parses the minor version from the URL.
To specify a specific minor version, use the version argument.
Maintain CLI version numbers in the data/products.yml file instead of updating individual links and code examples.
{{< latest-cli >}}
{{< latest-cli version="2.1" >}}Use the {{< api-endpoint >}} shortcode to generate a code block that contains
a colored request method and a specified API endpoint.
Provide the following arguments:
- method: HTTP request method (get, post, patch, put, or delete)
- endpoint: API endpoint
{{< api-endpoint method="get" endpoint="/api/v2/tasks">}}Shortcodes are available for creating "tabbed" content (content that is changed by a users' selection). Ther following three must be used:
{{< tabs-wrapper >}}
This shortcode creates a wrapper or container for the tabbed content.
All UI interactions are limited to the scope of each container.
If you have more than one "group" of tabbed content in a page, each needs its own tabs-wrapper.
This shortcode must be closed with {{< /tabs-wrapper >}}.
Note: The < and > characters used in this shortcode indicate that the contents should be processed as HTML.
{{% tabs %}}
This shortcode creates a container for buttons that control the display of tabbed content.
It should contain simple markdown links with anonymous anchors (#).
The link text is used as the button text.
This shortcode must be closed with {{% /tabs %}}.
Note: The % characters used in this shortcode indicate that the contents should be processed as Markdown.
{{% tab-content %}}
This shortcode creates a container for a content block.
Each content block in the tab group needs to be wrapped in this shortcode.
The number of tab-content blocks must match the number of links provided in the tabs shortcode
This shortcode must be closed with {{% /tab-content %}}.
Note: The % characters used in this shortcode indicate that the contents should be processed as Markdown.
{{< tabs-wrapper >}}
{{% tabs %}}
[Button text for tab 1](#)
[Button text for tab 2](#)
{{% /tabs %}}
{{% tab-content %}}
Markdown content for tab 1.
{{% /tab-content %}}
{{% tab-content %}}
Markdown content for tab 2.
{{% /tab-content %}}
{{< /tabs-wrapper >}}Shortcodes are also available for tabbed code blocks primarily used to give users the option to choose between different languages and syntax. The shortcode structure is the same as above, but the shortcode names are different:
{{< code-tabs-wrapper >}}
{{% code-tabs %}}
{{% code-tab-content %}}
{{< code-tabs-wrapper >}}
{{% code-tabs %}}
[Flux](#)
[InfluxQL](#)
{{% /code-tabs %}}
{{% code-tab-content %}}
```js
data = from(bucket: "example-bucket")
|> range(start: -15m)
|> filter(fn: (r) =>
r._measurement == "mem" and
r._field == "used_percent"
)
```
{{% /code-tab-content %}}
{{% code-tab-content %}}
```sql
SELECT "used_percent"
FROM "telegraf"."autogen"."mem"
WHERE time > now() - 15m
```
{{% /code-tab-content %}}
{{< /code-tabs-wrapper >}}To link to tabbed content, click on the tab and use the URL parameter shown.
It will have the form ?t=, plus a string.
For example:
[Windows installation](/influxdb/v2.0/install/?t=Windows)
Use the {{< req >}} shortcode to identify required elements in documentation with
orange text and/or asterisks. By default, the shortcode outputs the text, "Required," but
you can customize the text by passing a string argument with the shortcode.
{{< req >}}Output: Required
{{< req "This is Required" >}}Output: This is required
If using other named arguments like key or color, use the text argument to
customize the text of the required message.
{{< req text="Required if ..." color="blue" type="key" >}}When identifying required elements in a list, use {{< req type="key" >}} to generate
a "* Required" key before the list. For required elements in the list, include
{{< req "*" >}} before the text of the list item. For example:
{{< req type="key" >}}
- {{< req "\*" >}} **This element is required**
- {{< req "\*" >}} **This element is also required**
- **This element is NOT required**Use the color argument to change the color of required text.
The following colors are available:
- blue
- green
- magenta
{{< req color="magenta" text="This is required" >}}Use the {{< keybind >}} shortcode to include OS-specific keybindings/hotkeys.
The following parameters are available:
- mac
- linux
- win
- all
- other
<!-- Provide keybinding for one OS and another for all others -->
{{< keybind mac="⇧⌘P" other="Ctrl+Shift+P" >}}
<!-- Provide a keybind for all OSs -->
{{< keybind all="Ctrl+Shift+P" >}}
<!-- Provide unique keybindings for each OS -->
{{< keybind mac="⇧⌘P" linux="Ctrl+Shift+P" win="Ctrl+Shift+Alt+P" >}}Use the {{< diagram >}} shortcode to dynamically build diagrams.
The shortcode uses mermaid.js to convert
simple text into SVG diagrams.
For information about the syntax, see the mermaid.js documentation.
{{< diagram >}}
flowchart TB
This --> That
That --> There
{{< /diagram >}}Use the {{< filesystem-diagram >}} shortcode to create a styled file system
diagram using a Markdown unordered list.
{{< filesystem-diagram >}}
- Dir1/
- Dir2/
- ChildDir/
- Child
- Child
- Dir3/
{{< /filesystem-diagram >}}In many cases, screenshots included in the docs are taken from high-resolution (retina) screens. Because of this, the actual pixel dimension is 2x larger than it needs to be and is rendered 2x bigger than it should be. The following shortcode automatically sets a fixed width on the image using half of its actual pixel dimension. This preserves the detail of the image and renders it at a size where there should be little to no "blur" cause by browser image resizing.
{{< img-hd src="/path/to/image" alt="Alternate title" />}}- This should only be used on screenshots takes from high-resolution screens.
- The
srcshould be relative to thestaticdirectory. - Image widths are limited to the width of the article content container and will scale accordingly,
even with the
widthexplicitly set.
In some cases, it may be appropriate to shorten or truncate blocks of content. Use cases include long examples of output data or tall images. The following shortcode truncates blocks of content and allows users to opt into to seeing the full content block.
{{% truncate %}}
Truncated markdown content here.
{{% /truncate %}}Use the {{% expand "Item label" %}} shortcode to create expandable, accordion-style content blocks.
Each expandable block needs a label that users can click to expand or collpase the content block.
Pass the label as a string to the shortcode.
{{% expand "Label 1" %}}
Markdown content associated with label 1.
{{% /expand %}}
{{% expand "Label 2" %}}
Markdown content associated with label 2.
{{% /expand %}}
{{% expand "Label 3" %}}
Markdown content associated with label 3.
{{% /expand %}}Use the optional {{< expand-wrapper >}} shortcode around a group of {{% expand %}}
shortcodes to ensure proper spacing around the expandable elements:
{{< expand-wrapper >}}
{{% expand "Label 1" %}}
Markdown content associated with label 1.
{{% /expand %}}
{{% expand "Label 2" %}}
Markdown content associated with label 2.
{{% /expand %}}
{{< /expand-wrapper >}}Use the {{% caption %}} shortcode to add captions to images and code blocks.
Captions are styled with a smaller font size, italic text, slight transparency,
and appear directly under the previous image or code block.
{{% caption %}}
Markdown content for the caption.
{{% /caption %}}Section landing pages often contain just a list of articles with links and descriptions for each.
This can be cumbersome to maintain as content is added.
To automate the listing of articles in a section, use the {{< children >}} shortcode.
{{< children >}}The children shortcode can also be used to list only "section" articles (those with their own children),
or only "page" articles (those with no children) using the show argument:
{{< children show="sections" >}}
<!-- OR -->
{{< children show="pages" >}}By default, it displays both sections and pages.
Use the type argument to specify the format of the children list.
{{< children type="functions" >}}The following list types are available:
- articles: lists article titles as headers with the description or summary of the article as a paragraph. Article headers link to the articles.
- list: lists children article links in an unordered list.
- anchored-list: lists anchored children article links in an unordered list meant to act as a page navigation and link to children header.
- functions: a special use-case designed for listing Flux functions.
To include a "Read more" link with each child summary, set readmore=true.
Only the articles list type supports "Read more" links.
{{< children readmore=true >}}To include a horizontal rule after each child summary, set hr=true.
Only the articles list type supports horizontal rules.
{{< children readmore=true >}}Use the list_code_example frontmatter to provide a code example with an article
in an articles list.
list_code_example: |
```sh
This is a code example
```To include text from a file in /shared/text/, use the
{{< get-shared-text >}} shortcode and provide the relative path and filename.
This is useful for maintaining and referencing sample code variants in their native file formats.
- Store code examples in their native formats at
/shared/text/.
/shared/text/example1/example.js
/shared/text/example1/example.py- Include the files, e.g. in code tabs
{{% code-tabs-wrapper %}}
{{% code-tabs %}}
[Javascript](#js)
[Python](#py)
{{% /code-tabs %}}
{{% code-tab-content %}}
```js
{{< get-shared-text "example1/example.js" >}}
```
{{% /code-tab-content %}}
{{% code-tab-content %}}
```py
{{< get-shared-text "example1/example.py" >}}
```
{{% /code-tab-content %}}
{{% /code-tabs-wrapper %}}To include the text from one file in another file in the same
directory, use the {{< get-leaf-text >}} shortcode.
The directory that contains both files must be a
Hugo Leaf Bundle,
a directory that doesn't have any child directories.
In the following example, api is a leaf bundle. content isn't.
content
|
|--- api
| query.pdmc
| query.sh
| _index.md# Query examplescurl https://localhost:8086/queryTo include query.sh and query.pdmc in api/_index.md, use the following code:
{{< get-leaf-text "query.pdmc" >}}
# Curl example
```sh
{{< get-leaf-text "query.sh" >}}
```Avoid using the following file extensions when naming included text files since Hugo interprets these as markup languages:
.ad, .adoc, .asciidoc, .htm, .html, .markdown, .md, .mdown, .mmark, .pandoc, .pdc, .org, or .rst.
To include a query example with the children in your list, update data/query_examples.yml
with the example code, input, and output, and use the list_query_example
frontmatter to reference the corresponding example.
list_query_example: cumulative_sumEach children list type uses frontmatter properties when generating the list of articles.
The following table shows which children types use which frontmatter properties:
| Frontmatter | articles | list | functions |
|---|---|---|---|
list_title |
✓ | ✓ | ✓ |
description |
✓ | ||
external_url |
✓ | ✓ | |
list_image |

The icon shortcode allows you to inject icons in paragraph text.
It's meant to clarify references to specific elements in the InfluxDB user interface.
{{< icon "icon-name" >}}
Below is a list of available icons (some are aliases):
- add-cell
- add-label
- alert
- calendar
- chat

In many cases, documentation references an item in the left nav of the InfluxDB UI.
Provide a visual example of the navigation item using the nav-icon shortcode.
{{< nav-icon "tasks" >}}
The following case insensitive values are supported:
- admin, influx
- data-explorer, data explorer
- notebooks, books
- dashboards
- tasks
- monitor, alerts, bell
- cloud, usage
- disks, load data, load-data
- settings
- feedback
CSS Flexbox formatting lets you create columns in article content that adjust and
flow based on the viewable width.
In article content, this helps if you have narrow tables that could be displayed
side-by-side, rather than stacked vertically.
Use the {{< flex >}} shortcode to create the Flexbox wrapper.
Use the {{% flex-content %}} shortcode to identify each column content block.
{{< flex >}}
{{% flex-content %}}
Column 1
{{% /flex-content %}}
{{% flex-content %}}
Column 2
{{% /flex-content %}}
{{< /flex >}}{{% flex-content %}} has an optional width argument that determines the maximum
width of the column.
{{% flex-content "half" %}}The following options are available:
- half (Default)
- third
- quarter
Use the {{< tooltips >}} shortcode to add tooltips to text.
The 1st argument is the text shown in the tooltip.
The 2nd argument is the highlighted text that triggers the tooltip.
I like {{< tooltip "Butterflies are awesome!" "butterflies" >}}.The example above renders as "I like butterflies" with "butterflies" highlighted. When you hover over "butterflies," a tooltip appears with the text: "Butterflies are awesome!"
The InfluxDB documentation is "task-based," meaning content primarily focuses on what a user is doing, not what they are using. However, there is a need to document tools and other things that don't necessarily fit in the task-based style. This is referred to as "reference content."
Reference content is styled just as the rest of the InfluxDB documentation.
The only difference is the menu reference in the page's frontmatter.
When defining the menu for reference content, use the following pattern:
# Pattern
menu:
<project>_<major-version-number>_<minor-version-number>_ref:
# ...
# Example
menu:
influxdb_2_0_ref:
# ...When a user selects an InfluxDB product and region, example URLs in code blocks
throughout the documentation are updated to match their product and region.
InfluxDB URLs are configured in /data/influxdb_urls.yml.
By default, the InfluxDB URL replaced inside of code blocks is http://localhost:8086.
Use this URL in all code examples that should be updated with a selected provider and region.
For example:
```sh
# This URL will get updated
http://localhost:8086
# This URL will NOT get updated
http://example.com
```
If the user selects the US West (Oregon) region, all occurrences of http://localhost:8086
in code blocks will get updated to https://us-west-2-1.aws.cloud2.influxdata.com.
To exempt a code block from being updated, include the {{< keep-url >}} shortcode
just before the code block.
{{< keep-url >}}
```
// This URL won't get updated
http://localhost:8086
```
Some functionality is only supported in InfluxDB Cloud and code examples should
only use InfluxDB Cloud URLs. In these cases, use https://cloud2.influxdata.com
as the placeholder in the code block. It will get updated on page load and when
users select a Cloud region in the URL select modal.
```sh
# This URL will get updated
https://cloud2.influxdata.com
```
Version bumps occur regularly in the documentation. Each minor version has its own directory with unique content. Patch versions within a minor version are updated in place.
To add a new minor version, go through the steps below. This example assumes v2.0 is the most recent version and v2.1 is the new version.
-
Ensure your
masterbranch is up to date:git checkout master git pull
-
Create a new branch for the new minor version:
git checkout -b influxdb-2.1
-
Duplicate the most recent version's content directory:
# From the root of the project cp content/influxdb/v2.0 content/influxdb/v2.1 -
Find and replace all instances of the old version number with the new version (only within the new version directory). Be sure to find and replace both the following forms of the version number:
v2.0 -> v2.1 v2_0 -> v2_1 -
Add the new product and version tag taxonomy to the
config.tomlin the root of the project.[taxonomies] "influxdb/v2.0/tag" = "influxdb/v2.0/tags" "influxdb/v2.1/tag" = "influxdb/v2.1/tags"
-
Update the
latest_versionindata/products.yml:latest_version: v2.1
-
Copy the InfluxDB
swagger.ymlspecific to the new version into the/api-docs/v<version-number>/directory. -
Commit the changes and push the new branch to Github.
These changes lay the foundation for the new version.
All other changes specific to the new version should be merged into this branch.
Once the necessary changes are in place and the new version is released,
merge the new branch into master.
InfluxData uses Redoc to generate the full
InfluxDB API documentation when documentation is deployed.
Redoc generates HTML documentation using the InfluxDB swagger.yml.
For more information about generating InfluxDB API documentation, see the
API Documentation README.
