SignalFx Integrations

Each directory in this repository specifies a different integration with Splunk Infrastructure Monitoring. At a minimum, each directory must have the files README.md and meta.yaml. If the integration is associated with a fixed set of metrics, add the file metrics.yaml. The following sections describe these files in more detail.

If you add a new integration, in meta.yaml set useLegacyBuild: false. Never use the legacy build for new integrations.

Writing YAML multi-line text

By default, YAML text appears on a single line. Consider the following text:

description: While you may see this metric in your organization, it is for Infrastructure Monitoring internal use only.

The YAML processor displays the line as is, with a newline (\n) after the word "only".

To control wrapping or to use Markdown syntax in YAML text, add one of the following characters after the YAML field name and colon delimiter. For example, use the delimiter for a multi-line description:

description: >
    While you may see this metric in your organization,
    it is for Infrastructure Monitoring internal use only.

• > - For a block of text, this character strips out line breaks within the block and adds a single break at the end of the block.
• | - For a block of text, this character preserves line breaks and implements Markdown.
• Use ＞－ or │－ if you don't want a blank line after the text block.

For more information, do an Internet search for "YAML multi-line".

Meta.yaml

Each integration directory must have the file meta.yaml, which provides basic metadata for the integration. Use the following fields:

Example 1:

display_name: "AppDynamics Metrics Integration"
description: "AppDynamics metrics integration"
project_url: "https://github.com/signalfx/integrations/tree/master/appdynamics"
code: "https://github.com/signalfx/appd-integration"

metrics.yaml

To help users make sense of incoming data, add or edit metrics.yaml to describe each metric and dimension that the integration emits, including the following:

• Metric name: For example, sf.org.limit.hosts
• Type: "counter", "gauge", or "cumulative_counter". For example, type: gauge
• Description of what it measures: For example,

  description: |
    Your contract specifies this limit for the number of MTS you can create per
    per minute. If you exceed this rate, Infrastructure Monitoring stops creating MTS.

Sample dashboard(s)

To help users start with your integration, include a dashboard that users can import into their monitoring solution. Infrastructure Monitoring provides extended trial accounts for plugin developers that you can use to develop your dashboard. Contact Infrastructure Monitoring to learn more.

New Template System

To help Infrastructure Monitoring teams and other contributors control the text generated from this repo, including text in the integration tiles in the user interface and text in the user documentation, the build system is based entirely on that is based entirely on Jinja templates.

To enable the new template functionality for your particular integration, set useLegacyBuild: false in your meta.yaml file.

The Jinja template for an integration is the file README.md.jinja in the integration directory. The build process uses only that file.

The build process deserializes all *.yaml files in the integration directory and makes them available to the template context as a variable. For example, metrics.yaml is available as metrics in the template.

Include the following line at the top of the file README.md.jinja:

{% import "macros.jinja" as macros %}

This macro statement imports the macro helpers defined in the Jinja system. To learn more about Jinja macros, see the Jinja documentation section Macros.

To apply a Jinja template to an existing integration:

1. Create the file README.md.jinja in the integration directory. You can either create it from scratch or copy and rename a legacy README.md file.
2. Ensure that README.md.jinja has the content that you want to describe, because it's the single source for integration tiles in the user interface and user documentation.
3. Verify that README.md.jinja file starts with the line {% import macros.jinja as macros %}.
4. In the file meta.yaml file for the integration, set useLegacyBuild: false so that the build process uses the Jinja template by default.
5. Delete the file README.md if it exists.

If possible, include all steps of the template application process in a single commit or pull request to your development branch. If you have useLegacyBuild: true, the build process ignores README.md.jinja or generates unexpected results. Similarly, if you have README.md.jinja and README.md in the same directory, your pull requests might generate file conflicts, because the build process merges all *.md files in your directory.

Tile Tabs

To control tabs in the integration tiles in the user interface, use second-level headers (specified by "##" in the first two columns of the header text) in README.md.jinja. The build process interprets a second-level header as the title of a tab, and all the content between the header and the next second-level header (or end of file) is displayed in the tab.

You can use first-level headers ("#") for text you want to display in user documentation. Otherwise, text that's outside a second-level section in README.md.jinja doesn't display in the integration tiles in the user interface.

Differentiate between tile content and documentation content

To control where content appears, use Jinja conditional statements and the target macro variable. To build integration tiles for the user interface, use target: tile. To build user documentation, use target: docs.

Build scripts write the output for target: tile to the integrations repository, while build scripts for target: docs write output to the product-docs repository. For example, the "if" statements in the following example write their content to the integrations repository but not the product-docs repository.

Conditional statements must be paired. Close the if statement with an endif statement:

Conditional text example

{% if target ﹦﹦ "tile" -%}

Test Tiles locally

The integration tiles used in the user interface come from a Javascript module that uses the content in the integrations repository. To build the module, use the ./build script in the root of the repository, as follows:

1. Verify that you have Python 3 installed on your machine.

2. In your terminal application, navigate to the root of the integrations repository.

3. Run the following command:

   pip3 install --user -r ./requirements.txt

4. Run the following command:

   ./build

If the build completes successfully, it displays a command that you can run to serve the JS module and associated images using a local HTTP server.

You can then run the user interface with the following content in the local.config.js file in the root of the SignalView repository:

module.exports = {
    integrationsDocsUrl: "http://localhost:3005/"
}

Run your local SignalView instance to preview the latest build of this repository.
