OpenTelemetry UserInteraction Instrumentation for web

This module provides automatic instrumentation for user interactions for Web applications, which may be loaded using the @opentelemetry/sdk-trace-web package.

If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-web bundle with @opentelemetry/sdk-trace-web for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK 1.0+.

This module can work either with zone-js or without it, with zone-js and ZoneContextManager it will fully support the async operations. Without zone-js it will still work but with limited support. If you use Angular or @opentelemetry/context-zone you will have zone-js included.

Installation

npm install --save @opentelemetry/instrumentation-user-interaction

Usage

Initialize

import { ConsoleSpanExporter, SimpleSpanProcessor } from '@opentelemetry/sdk-trace-base';
import { WebTracerProvider } from '@opentelemetry/sdk-trace-web';
import { UserInteractionInstrumentation } from '@opentelemetry/instrumentation-user-interaction';
import { ZoneContextManager } from '@opentelemetry/context-zone';
import { registerInstrumentations } from '@opentelemetry/instrumentation';
// or if you already have zone.js
// import { ZoneContextManager } from '@opentelemetry/context-zone-peer-dep';

const provider = new WebTracerProvider({
  contextManager: new ZoneContextManager()
});

provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.register();

registerInstrumentations({
  instrumentations: [
    new UserInteractionInstrumentation(),
  ],
});

// and some test
const btn1 = document.createElement('button');
btn1.append(document.createTextNode('btn1'));
btn1.addEventListener('click', () => {
  console.log('clicked');
});
document.querySelector('body').append(btn1);

const btn2 = document.createElement('button');
btn2.append(document.createTextNode('btn2'));
btn2.addEventListener('click', () => {
  getData('https://httpbin.org/get').then(() => {
    getData('https://httpbin.org/get').then(() => {
      console.log('data downloaded 2');
    });
    getData('https://httpbin.org/get').then(() => {
      console.log('data downloaded 3');
    });
    console.log('data downloaded 1');
  });
});
document.querySelector('body').append(btn2);

function getData(url) {
  return new Promise(async (resolve) => {
    const req = new XMLHttpRequest();
    req.open('GET', url, true);
    req.setRequestHeader('Content-Type', 'application/json');
    req.setRequestHeader('Accept', 'application/json');
    req.send();
    req.onload = function () {
      resolve();
    };
  });
}

// now click on buttons

Send spans for different events

By default, only click events are automatically instrumented. To automatically instrument other events, specify the events that should be captured for telemetry. Most HTMLElement interface events are supported.

import { UserInteractionInstrumentation } from '@opentelemetry/instrumentation-user-interaction';
import { registerInstrumentations } from '@opentelemetry/instrumentation';

// ...general opentelemetry configuration

registerInstrumentations({
  instrumentations: [
    new UserInteractionInstrumentation({
      eventNames: ['submit', 'click', 'keypress'],
    }),
  ],
});

Prevent spans from recording

import { UserInteractionInstrumentation } from '@opentelemetryinstrumentation-user-interaction';
import { registerInstrumentations } from '@opentelemetry/instrumentation';


// ...general opentelemetry configuration

registerInstrumentations({
  instrumentations: [
    new UserInteractionInstrumentation({
      shouldPreventSpanCreation: () => {
        return true;
      },
    }),
  ],
});

Add extra attributes to spans

To attach extra attributes to user interaction spans, provide a callback function to the shouldPreventSpanCreation option:

import { UserInteractionInstrumentation } from '@opentelemetryinstrumentation-user-interaction';
import { registerInstrumentations } from '@opentelemetry/instrumentation';

// ...general opentelemetry configuration

registerInstrumentations({
  instrumentations: [
    new UserInteractionInstrumentation({
      shouldPreventSpanCreation: (event, element, span) => {
        span.setAttribute('target.id', element.id);
        // etc..
      }
    }),
  ],
});
