Add a domain to watch
Requires a periodic job to actually collect data - see the "Set up monitoring" note below.
Set up monitoring (one-time)
This page only manages the watch list. To actually collect data points and send alerts, add a cPanel Cron Job that runs every 15-30 minutes:
php /home/thednscheck/public_html/cron_check.php
If your host doesn't offer shell/CLI cron, you can instead use an external scheduler (e.g. a free uptime-ping service or cron-job.org) to hit this URL every 15-30 minutes:
https://your-domain/path/cron_check.php?secret=YOUR_CRON_SECRET
Set your own random CRON_SECRET in config.php first.
