An Apps Script that polls Webpagetest weekly and puts the result into a Google Sheet. If metrics exceed your thresholds, you'll get an email. A great way to make sure your site doesn't slow down!

This is meant to be used in the Google Sheet at https://goo.gl/SgMfGc.

Here's how it works:

  1. You create a tab in the Google Sheet for each URL whose speed you want to track.
  2. Once a week, the tool runs Webpagetest on each of those URLs.
  3. The tool retrieves key performance metrics from those tests, placing those in a new row in each tab.
  4. If any metric exceeds thresholds you’ve set, it sends alerts to email addresses also stored in the trix.

That’s it!

Setup:

  1. Make your own copy of the Sheet.

  2. Get an API key and configure this tool to use it.

  • Get an API key from Webpagetest by filling out the simple form here.
  • Go to the Config tab.
  • Replace the API key in cell B1 with your own.
  1. Specify your URLs.
  • In the “URL 1” tab, replace the URL in column B1 with the URL you want tested.
  • If you want to test more URLs, copy the URL 1 tab. You can test as many as 10 URLs. Just make sure that the name of each tab starts with “URL”.
  1. In the Alerting tab, enter email addresses for people who should get alerts.

  2. Set up weekly tests:

  • Under the “Tools” menu, select “Script Editor”. A new browser tab will open.
  • In that new tab, go to the “Edit” menu and choose “Current project’s triggers”.
  • In the popup window, click on “Add a new trigger”, and set it up as shown (weekly tests are recommended, but you can decide)

That’s it! Enjoy!

Warning about a warning:

An Apps Script can now go through a verification process whereby Google ensures it's safe. Since you'll own this script, it won't be verified in this way. So, when you first run it, you'll probably see a scary warning that begins, "This app isn't verified."

You'll simply have to click on the "Advanced" link in that dialog box and tell Google you trust the script.
