IBM Telemetry JS

JavaScript telemetry tooling for open/inner source projects

Quality metrics

Overview

IBM Telemetry collects anonymized usage data for open source and inner source packages when they have been instrumented with this JavaScript tooling. The data is reported back to a central server so package maintainers can analyze usage and make improvements.

IBM Telemetry uses OpenTelemetry as the foundation of its data transport format.

IBM Telemetry collection basics

If you're reading this section, you're likely using a package and have noticed that it is collecting telemetry data using IBM Telemetry. We call that an "instrumented package". Here's what you need to know about how that works:

Telemetry data collection runs on CI servers, like GitHub Actions, Travis CI, or Jenkins. It never runs locally on a developer's machine.
When npm install (or equivalent) is run on the CI server (resulting in the instrumented package getting installed), IBM Telemetry gets installed too and runs a script which analyzes your source code and captures data about your usage of the instrumented package.
This data is fully anonymized and reported back to a server at IBM.
For more details about exactly what is captured and how sensitive data is anonymized, keep reading.
Though IBM Telemetry is installed as a regular dependency in the instrumented package, it has no exports and therefore does not impact your project's source code or build output in any way. Said differently: This is not a runtime package. It has no "shippable code". It is static source code analysis performed during builds and nothing more.

The point of capturing this data is to help the open source and inner source maintainers within IBM by giving them meaningful insights and metrics based on actual data. IBM Telemetry's purpose is to enable data-driven decision-making to enable maintainers to focus on features that are actually used by developers like you.

What data gets collected?

Depending on the nature of the instrumented package and its telemetry configuration, IBM Telemetry may capture the following data about your project:

General

Date and time of collection
A de-identified version of your project's git repository URL
A de-identified version of your project's most recent Git commit hash
De-identified versions of the branches and tags associated with that commit hash

NPM data

A de-identified version of your project's name (as defined in your package.json file)
Your project's version (as defined in package.json) with any identifiable parts removed
De-identified names and versions of your project's dependencies

JSX data

JSX elements (aka components) imported by your project from the instrumented package and details about the elements’ attributes (aka props) including names, values, and import paths.

Element attribute names that haven't been specifically configured by the instrumented package to be collected will be anonymized before collection.

Boolean and number values will be captured for allowed attribute names. String values that haven't been specifically configured by the instrumented package and other value types (such as complex objects or variable names) are also anonymized. This means your project-specific data supplied to JSX elements will never be captured.

All sensitive data that may contain confidential or personally identifiable information that gets collected by the IBM Telemetry JS tooling gets anonymized/de-identified prior to storage in our database, see anonymizing.

When does data get collected?

Telemetry collection runs exclusively in CI environments. Collection will never happen on local development environments or on projects that aren't configured to run automated scripts on a CI environment (GitHub actions, Travis CI, etc.)

During a build or any other CI operation that installs package dependencies (npm install, yarn install, ...), IBM telemetry will run as a background process and perform data collection.

Opting out of IBM Telemetry data collection

IBM Telemetry will collect metric data for instrumented packages by default. If your project is installing an IBM Telemetry-instrumented package and you want to opt-out of metric collection, set an environment variable of IBM_TELEMETRY_DISABLED='true'. This will prevent any and all data from being collected in your project.

Anonymizing / de-identifying

When data is to be de-identified, it is hashed using the SHA-256 cryptographic function, meaning an instrumented package owner can query for specific known names/values but can never recover original values from the stored data in the database.

When data is to be anonymized, it is redacted/substituted in a way where its original value can never be recovered, and there is no meaningful way to query the data to ascertain its value.

As a general philosophy, we favor anonymizing fields over de-identifying them.

Onboarding a package to IBM Telemetry

1. Obtain a project ID from the IBM Telemetry team by opening an issue here.

The IBM Telemetry team will assign you a project ID to include in your telemetry.yml config file.

2. Create a `telemetry.yml` config file.

!IMPORTANT This config file needs to be included in your published NPM package!

This file defines what types of metrics will be captured for your project as well as some general configuration settings.

See the telemetry config schema for a detailed explanation of all available configuration options.

Sample:

# yaml-language-server: $schema=https://unpkg.com/@ibm/telemetry-config-schema@0.3.0/dist/config.schema.json
version: 1
projectId: '<your assigned project id>'
endpoint: 'https://example.com/v1/metrics'
collect:
  npm:
    dependencies: null
  jsx:
    elements:
      allowedAttributeNames:
        - 'size'
        - 'title'
        - 'etc.'
      allowedAttributeStringValues:
        - 'small'
        - 'medium'
        - 'large'
        - 'title1'
        - 'title2'
        - 'etc.'

Note: Though this file can live anywhere within your project, it is customary to place it at the root level.

Optionally, use the IBM Telemetry Js Config Generator script to automatically generate the config file. Remember to verify that the generated output is correct before using the config file.

3. Install `@ibm/telemetry-js` dependency.

Note: This must be installed as a regular dependency, not a dev dependency in the instrumented project.

npm install @ibm/telemetry-js

yarn add @ibm/telemetry-js

4. Add a `postinstall` script to your `package.json` file.

The postinstall script runs telemetry collection anytime your package gets installed inside of another project.

// ...
"scripts": {
  // ...
  "postinstall": "ibmtelemetry --config=path/to/your/telemetry.yml"
}
// ...

Make sure the --config option points to your telemetry.yml file within your package.

5. Add telemetry collection notice to your docs.

You'll want to be as transparent as possible about telemetry collection and the data that is being stored. You should strongly consider adding an informational paragraph to your docs (usually the README) as follows:

## <picture><source height="20" width="20" media="(prefers-color-scheme: dark)" srcset="https://raw.githubusercontent.com/ibm-telemetry/telemetry-js/main/docs/images/ibm-telemetry-dark.svg"><source height="20" width="20" media="(prefers-color-scheme: light)" srcset="https://raw.githubusercontent.com/ibm-telemetry/telemetry-js/main/docs/images/ibm-telemetry-light.svg"><img height="20" width="20" alt="IBM Telemetry" src="https://raw.githubusercontent.com/ibm-telemetry/telemetry-js/main/docs/images/ibm-telemetry-light.svg"></picture> IBM Telemetry

This package uses IBM Telemetry to collect metrics data. By installing this package as a dependency
you are agreeing to telemetry collection. To opt out, see
[Opting out of IBM Telemetry data collection](https://github.com/ibm-telemetry/telemetry-js/tree/main#opting-out-of-ibm-telemetry-data-collection).
For more information on the data being collected, please see the
[IBM Telemetry documentation](https://github.com/ibm-telemetry/telemetry-js/tree/main#ibm-telemetry-collection-basics).

6. Publish a new version of your package.

Package consumers need to install a version of your package that includes both the config file and post-install script in order for telemetry collection to occur.

7. Done!

Whenever consumers pick up a version of your package that includes the config file and post-install script, telemetry collection will run and collect metrics.

I don't work for IBM. Can I still use this?

Yes! This package can send its output to any OpenTelemetry-compatible collector endpoint via the standard v1/metrics Rest API endpoint. All you need to do is specify your collector endpoint's URL in the endpoint configuration setting in your telemetry.yml file.
