@salesforce/telemetry

sfdx-telemetry

This package serves an interface for Microsoft's Application Insights npm module and supports O11y (Observability) telemetry.

Install

yarn add @salesforce/telemetry --save

Usage

For long running process

import TelemetryReporter from '@salesforce/telemetry';

const reporter = await TelemetryReporter.create({ project: 'my-project-name', key: 'my-instrumentation-key' });
reporter.start();

// Now you can send events and the reporter will batch and send.
reporter.sendTelemetryEvent('event-name', { foo: 'bar', executionTime: 0.5912 });

By default, some common properties are hidden for GDPR. This is to protect client side tools that send telemetry. If the owner of the long running process controls the machines too, you can redefine the GDPR sensitive fields.

const reporter = await TelemetryReporter.create({
  project: 'my-project-name',
  key: 'my-instrumentation-key',
  gdprSensitiveKeys: [],
});

For short lived processes

import TelemetryReporter from '@salesforce/telemetry';

const reporter = await TelemetryReporter.create({ project: 'my-project-name', key: 'my-instrumentation-key' });

// Send events.
reporter.sendTelemetryEvent('event-name', { foo: 'bar', executionTime: 0.5912 });

// When all finished sending events, stop the reporter or the process may hang.
reporter.stop();

Note: For short lived processes, the telemetry can take 0-3 seconds to send all events to the server on stop, and even longer if there is a timeout. It is recommended to send telemetry in a detached spawned process. i.e. spawn(..., { stdio: 'ignore'}).unref();

O11y (Observability) Telemetry

The telemetry reporter also supports O11y telemetry alongside Application Insights. To enable O11y telemetry, provide the enableO11y and o11yUploadEndpoint options:

const reporter = await TelemetryReporter.create({
  project: 'my-project-name',
  key: 'my-instrumentation-key', // Required for Application Insights
  enableO11y: true,
  o11yUploadEndpoint: 'https://your-o11y-endpoint.com/upload',
  extensionName: 'my-extension' // Optional, defaults to project name
});

O11y-Only Mode

For O11y-only telemetry (without Application Insights), you can disable AppInsights explicitly:

const reporter = await TelemetryReporter.create({
  project: 'my-project-name',
  enableO11y: true,
  enableAppInsights: false, // Disable AppInsights
  o11yUploadEndpoint: 'https://your-o11y-endpoint.com/upload',
  extensionName: 'my-extension' // Optional, defaults to project name
});

Note: O11y telemetry respects the same telemetry enablement settings as Application Insights. If telemetry is disabled via SF_DISABLE_TELEMETRY or other configuration, O11y events will not be sent.

Env Variables

SF_DISABLE_TELEMETRY: Set to true if you want to disable telemetry.
