In the days of the Covid-19 lockdown in Ho Chi Minh, Vietnam. I have been working from home for the past 2 months. In my free time, I share how to create a status statistics page, although it seems quite new or there are paid packages with great features, but for personal needs I choose free services.
You can see my site demo at http://status.eplus.dev
Sign up for an account
Enter the website address you need to track
See the stats page we just created will have the format https://updown.io/xxxx . Example: https://updown.io/2yy9
Don't forget to make your page public
Custom domain status page
In order to have your status page available under your own subdomain, you need to create a CNAME record from your subdomain to xxxx.status.updown.io (xxxx being your check token, visible in your status page URL).
For example, in order to direct https://status.example.com to https://updown.io/2yy9, you need to create a CNAME entry status.example.com pointing to 2yy9.status.updown.io. Example: https://status.eplus.dev
An SSL certificate will automatically be generated for your custom domains. Also, your status page must be PUBLIC, otherwise you'll get a 404.
Good luck
