Feed a Puppeteer script to Watchmen to run synthetic monitoring.

In your Watchmen directory: npm install watchmen-ping-puppeteer --save

How To Use:

  • Important This runs on Node v7.4 or higher to use async/await otherwise, you'll have to compile down.
  • Create a Puppeteer script with a .js extension
const puppeteer = require('puppeteer');

async function getImageAltText() {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('');

  let selector = '.xfinity-logo';
  let imageSelector = await page.$('img');
  let getImage = await page.evaluate(image => image.alt, imageSelector);
  try {
    await page.waitForSelector(selector).then(getImage);
  } catch (err) {
    const browserClose = await browser.close();
    return `Failed to retrieve selector ${err}`;

  if (getImage === 'comcast official logo, xfinity official logo') {
    return 'Title Found';
  } else {
    throw 'Failure: title does not match';

getImageAltText().then(success => {
  return success;
}).catch(err => {
  process.exitCode = 1;
  return err;
