HTTP & HTTPS — website uptime monitoring
HTTP and HTTPS monitoring is the most common type of check. Alive24x7 visits your URL at regular intervals — just like a visitor would — and checks that your website or API returns a successful response. If it does not, you get an alert.
When is a monitor marked DOWN?
Your monitor is marked DOWN if any of the following happen during a check:
- The server returns an error status code (anything outside the 200–299 range, such as 404 Not Found or 500 Internal Server Error)
- The connection is refused — the server is not listening on that port
- The domain name cannot be resolved (DNS failure)
- The request does not complete within the timeout period
- For HTTPS: the SSL certificate is invalid or the TLS handshake fails
What to enter in the URL field
Enter the full URL including the protocol. For example: https://yourwebsite.com, https://api.yourapp.com/health, or http://192.168.1.10/status. The URL must be reachable from the internet — Alive24x7 cannot monitor URLs on private networks or behind a VPN.
Check frequency
| Plan | Fastest check interval |
|---|---|
| Trial | Every 60 seconds |
| Starter | Every 60 seconds |
| Pro | Every 30 seconds |
| Team | Every 30 seconds |
Timeout
The timeout is the maximum amount of time Alive24x7 waits for a response before marking the check as failed. The default is 30 seconds. You can lower this if you want to be alerted when your site is slow to respond, or raise it for services that are expected to take longer.
User-Agent: Alive24x7/1.0. If your server or firewall blocks unknown user agents, you may need to add this to your allowlist.Geographic monitoring locations
On Pro and Team plans, all monitor types (including HTTP, HTTPS, Keyword, Ping, DNS, TCP Port, and SSL) can be checked from a specific geographic region using Globalping. See Geographic monitoring locations for full details.
