We are ready with a brand-new check type - the Page Speed check.
First things first, what exactly is it, and what does it do? Glad you asked!
The primary purpose of this check is to monitor your sites (yes, you guessed it) page speed. Unlike our Uptime check, we test the site from a real Chrome Browser. This means that we download all the content from the page and then renders it in a Chrome browser.
By doing this, we are able to get the pages load time, among many other things. Why? To make sure that your site is stable and the visitors are actually able to view your content. Your website might be "up" (responding with a "status code 200"), but if it takes 10+ seconds to load it might as well be down, because:
But that is not all - oh no sir, no. We got some more delicious treats for you. Besides load time we also record:
- Largest Contentful Paint is one of the core web vitals that measures how long it takes for the largest content element in the viewport to become visible. You can read more about it here -Optimize Largest Contentful Paint.
- Page size is the total size of the page shown in megabyte (MB). We also show the uncompressed size.
- Requests are the number of files being requested for the page (HTML-, CSS-, JS-files, images, videos, etc.)
- Page errors show the number of console errors found on the page.
- Page warnings show the number of console warnings found on the page.
- A screenshot of the page (1366x768 resolution).
Pretty cool, right? But that is not all.
For each test, we run (you can run one every 10. minute) we also capture a full list of any page errors/warnings and a full Waterfall Analysis of all the file requests. You can find this by clicking the "View latest test result"-button on the check report page or by clicking on any of the entries in the log list.
To create your first Speed check, simply click on the "Add check"-button and select Speed check.
