How to monitor the status of an HTTP URL?

This article explains the proper procedure to monitor the status of a specific URL (such as http://192.168.0.200:8080/sistema) in Monsta, checking whether it responds with an HTTP/200 (OK) status.

❌ Common Mistake

Section titled “❌ Common Mistake”

It’s a common mistake to try to add the full URL path (ex: http://192.168.0.200:8080/sistema) in the Device Address field on the device screen.

The Device Address field accepts only the IP or hostname (ex: 192.168.10.16, www.foo.com). It is used to identify the device and does not check URL paths or ports.
