This module provides a consistent way for extensions to report telemetry over Application Insights. The module respects the user's decision about whether or not to send telemetry data. See telemetry extension guidelines for more information on using telemetry in your extension.

Follow guide to set up Application Insights in Azure and get your key. Don't worry about hardcoding it, it is not sensitive.


With npm: npm install @vscode/extension-telemetry With yarn: yarn add @vscode/extension-telemetry



import * as vscode from 'vscode';
import TelemetryReporter from '@vscode/extension-telemetry';

// the application insights key (also known as instrumentation key)
const key = '<your key>';

// telemetry reporter
let reporter;

function activate(context: vscode.ExtensionContext) {
   // create telemetry reporter on extension activation
   reporter = new TelemetryReporter(key);
   // ensure it gets properly disposed. Upon disposal the events will be flushed

Sending Events

Use this method for sending general events to App Insights.

// send event any time after activation
reporter.sendTelemetryEvent('sampleEvent', { 'stringProp': 'some string' }, { 'numericMeasure': 123 });

Sending Errors as Events

Use this method for sending error telemetry as traditional events to App Insights. This method will automatically drop error properties in certain environments for first party extensions. The last parameter is an optional list of case-sensitive properties that should be dropped. If no array is passed, we will drop all properties but still send the event.

// send an error event any time after activation
reporter.sendTelemetryErrorEvent('sampleErrorEvent', { 'stringProp': 'some string', 'stackProp': 'some user stack trace' }, { 'numericMeasure': 123 }, [ 'stackProp' ]);
