Tracks

Tracks are composed of levels, checks and certifications. Tracks encourage alignment to architectural best practices and standards and are analogous to an organization’s long-term tech health initiatives. Tracks are composed of one or more levels, and each level is composed of one or more checks. Each level of checks sets the standard for an organization and how they want to determine what passes and what fails in the individual track.

Managing tracks via the no-code UI

Creating a new track

To create a track, give your track a meaningful name and a description, and select the filters and checks that you want to use.

Filters allow a user further customization for their tracks to only be applicable to specific entities in the Software Catalog. This allows users to tie their tracks to specific tags such as “Java”, “service” or “production” to name a few. You can have as many or as few selections per type as you want to include in each track. Each type of filter will display a dropdown menu with your choice for selection. You can select any number of filters per section as desired.

Checks are searchable, and can be dragged-and-dropped from the list of checks into the level(s) of the track. Levels can be added to a track with the “+ Add Level” button shown above. Organizing checks into levels allows for a more nuanced read of what checks cleared and which ones didn’t. Most use levels by order of difficulty to clear, where level one means hardest to pass, level two is medium hard to pass, and level three is relatively easy to pass.

Editing a track

Once a track is created, you will be able to manage and edit your track on its detail page. From the tracks listing page, you will see an option to edit your track, which will bring you to the details page shown below.

As with checks, you can make as many changes as desired when editing tracks. Just make sure to save your track in order for changes to take effect. Also, similar to checks,, editing a track and saving will immediately reflect onto anything that has been assigned to said track.

Export to YAML

Checks can be saved as YAML via the dropdown menu on the track cards.

Associated checks are not exported. You must export these seperately and ensure the id fields match.

Managing tracks via yaml configuration

Tracks can be created in code via yaml configuration files.

Overall Shape Of A Track

The following is an example of a descriptor file for a Soundcheck Track (more examples):

- id: test-certified
  name: Test Certified
  ownerEntityRef: group:default/example-owner
  description: >
    Improve quality and reliability of your software component by measuring the use of testing best practices.
  documentationURL: https://www.backstage.io
  filter:
    catalog:
      metadata.tags: python
  levels:
    - ordinal: 1
      checks:
        - id: python_service_runs_tests
          name: The python service runs pytest
          description: >
            This service is currently running pytest as part of its GitHub actions workflow as defined in the build.yaml
    - ordinal: 2
      checks:
        - id: github_actions_tests_passing
          name: CI/CD Tests passing
          description: >
            The last tests run in GitHub Actions was successful.

See below for details about these fields.

Adding yaml tracks to your track library

To add tracks defined in a yaml file to your track library, you need to source them in you app-config.yaml. You have the option of storing them locally or remotely.

Here is an example configuration should your tracks yaml files be local to your Backstage project:

app-config.yaml

soundcheck:
  programs:
    - $include: ./path-to-local-folder/tracks-file-1.yaml
    - $include: ./path-to-local-folder/tracks-file-2.yaml
    - $include: ./path-to-local-folder/tracks-file-3.yaml

To maintain your tracks files in a remote repo, you can source them in app-config.yaml in a similar manner. Here is an example configuration:

app-config.yaml

soundcheck:
  programs:
    - https://github.com/user/repo/blob/main/tracks-file-1.yaml
    - https://github.com/user/repo/blob/main/tracks-file-2.yaml
    - https://github.com/user/repo/blob/main/tracks-file-3.yaml
  remote_file_updates:
    disabled: false
    frequency:
      minutes: 5

Note: you cannot combine local and remote sourcing for tracks files. This includes the usage of $include within a remotely sourced tracks file. The below option will NOT work:

app-config.yaml

soundcheck:
  programs:
    - https://github.com/user/repo/blob/main/tracks-file-1.yaml
    - https://github.com/user/repo/blob/main/tracks-file-2.yaml
    - $include: ./path-to-local-folder/tracks-file-3.yaml

Remote file update options

The remote_file_updates object is optional configuration allowing you to control if and when Soundcheck looks for updates within your remote files. This configuration is global for Soundcheck, so will apply to both track and check files. If not explicitly set, see the below for default values.

Key	Default	Description
disabled	false	Enables Soundcheck to look for updates in remote files
frequency	minutes: 5	The frequency at Soundcheck will look for updates in remote files. Possible values are either a cron expression { cron: ... } or HumanDuration.

Track Fields

The Track object is composed of some top level summary fields as well as more complex nested fields for filters and levels.

Field	Required	Description
id	Yes	Unique identifier for this particular Soundcheck Track.
name	Yes	Human-readable identifier for this particular Soundcheck Track.
description	Yes	Additional details about the motivation behind this set of checks.
ownerEntityRef	Yes	Relates this Soundcheck Track to the person or team responsible for maintaining it.
documentationURL	No	Link users can follow for more details about this track.
group	No	Connects logically similar but functionally disjoint tracks into groups.
filter	No	Specifies the type of entities that a particular track applies to.
levels	Yes	Offers an additional layer of specificity on top of the track definition.

Example

Level Fields

The level object is composed of several top-level summary fields and a repeated check definition field.

Field	Required	Description
ordinal	Yes	Uniquely identifies a particular level within a track.
name	No	Provides a human-readable title for the level.
description	No	Allows further expression regarding the purpose of a level.
checks	Yes	Specifies all the checks an entity must pass to be certified at this level.

Check Fields

The check object defines the atomic unit of work within the Soundcheck certification process.

Field	Required	Description
id	Yes	Links this definition to the actual check results.
name	Yes	Provides the human-readable title for this check.
description	Yes	Provides additional context on the motivation and implementation of check.
filter	No	Allows further filtering of checks within a track definition.

Entity Filter

Filter objects narrow down applicability for both tracks and checks. Currently, Soundcheck supports filtering based on the shape of a Software Catalog Entity.

CatalogFilter

CatalogFilters consist of a map of FilterKey to FilterValue, and an Entity matches a CatalogFilter if every entry in the filter matches the Entity.

Field	Description
FilterKey	Represents specific subsets of fields within the Software Catalog Entity descriptor.
FilterValue	Represents patterns for entity matching.

FilterKey

FilterKeys represent specific subsets of fields within the Software Catalog Entity descriptor, categorized as follows:

Type	Description
String	'kind', 'spec.type', 'spec.lifecycle', 'spec.owner', 'spec.system'
Array	'metadata.tags'
Record	'metadata.annotations' (e.g., 'metadata.annotations["backstage.io/techdocs-ref"]'), 'metadata.labels'

FilterValue

FilterValues represent patterns for entity matching:

Type	Description
String	Checks if the Entity property specified by the corresponding FilterKey matches the provided value.
Array	Checks if the Entity property specified by the corresponding FilterKey matches any string in the array.
Presence	Tests presence/absence of a FilterKey in an Entity.

Examples

String

Soundcheck checks whether the Entity property specified by the FilterKey matches the provided string value (case insensitive).

filter:
  catalog:
    spec.lifecycle: 'production'

Array Example

Soundcheck checks whether the Entity property specified by the FilterKey matches any of the strings in the provided array value (case insensitive).

filter:
  catalog:
    spec.type: ['service', 'website']

Presence

ValueMatcher FilterValues test for the presence or absence of a particular FilterKey in an Entity. * considers any value (except undefined) a match, and !* only matches missing or undefined values.

filter:
  catalog:
    metadata.annotations["backstage.io/techdocs-ref"]: { match: '*' }
    metadata.annotations["wikipedia.org"]: { match: '!*' }

Integrating with Soundcheck

Soundcheck enables developers to evaluate software components against standards through the creation of tracks, levels, and checks.

Fact Framework

Soundcheck's fact framework collects information about an entity using Fact Collectors or the Facts API.

Fact Collectors

Collector	Description
Catalog	Collects facts from Backstage's Software Catalog as fact data.
Soundcheck	Exposes Soundcheck track certifications as facts.

Third Party Integrations

Integration	Description
Source Control Management (SCM)	Provides integration with source control management providers.
GitHub	Enables gathering facts regarding GitHub repositories.

Fact Checks

Fact checks define rules that determine whether a check result should pass or fail.

Field	Description
id	Unique identifier for this fact check.
name	A name for the fact check suitable for display.
description	A description of the fact check.
rule	Conditions that determine check pass/fail.
schedule	How often and on which entities to run the check.

Executing Checks

Fact checks are executed, or triggered, by Soundcheck in the following ways:

1. A dependent fact is updated, either through fact collectors or via the Facts API.
2. A fact check is scheduled, in which case Soundcheck will automatically execute the check on the specified frequency.
3. A fact check is manually triggered via the Checks API.

REST API

We include a REST API for Tracks. See API Reference for details.

Certifications

L1 L2 L3

Certifications and badges incentivize Engineers to complete levels through Gamification. Component owners can achieve bronze, silver, and gold badges upon completion of related levels.

Certification History

By default, Soundcheck certifies entities against their applicable tracks on demand, so that certifications (the highest level of the track that has all checks passing) are never stored in the database. However, it's possible to enable tracking of certification history in order to track the change in the highest certified levels for every entity and their applicable tracks over time.

Soundcheck does not currently provide an API for interacting with certification history. However, the certification history data is used by Soundcheck Tech Health page to visualize snapshots and trends of the highest certified levels for every entity and their applicable tracks. It's also possible for other systems to integrate with certification history by reading from the Soundcheck database directly.

Enabling Certification History

To enable check result history, set soundcheck.certifications.history.enable to true in config:

app-config.yaml

soundcheck:
  certifications:
    history:
      enable: true

Reading Certification History

Certification history is stored in the certification_history table in the Soundcheck database. Unless overridden in Backstage configuration, the Soundcheck database will be part of the main Backstage database, and named backstage_plugin_soundcheck.

SELECT *
FROM certification_history
WHERE entity_ref = 'component:default/example-component';

Certification History Schema

• certification_id - Unique identifier for the certification (primary key).
• entity_ref - Entity reference that the certification relates to.
• owner_entity_ref [optional] - Software catalog entity that owns the entity this certification is for.
• track_id - Unique identifier for the track this certification is for.
• scope - The scope of check results this certification was created for.
• highest_level [optional] - Rank of the highest certified level. Null if no level is certified.
• certification_date - The date of the certification.
• last_updated - The timestamp indicating the date and time when the certification was last updated.
