HTTP monitor overview

We’re changing our user interface. Some info may not yet be up to date. Please check From classic to new UI.

An HTTP monitor checks for your web pages' availability from the designated checkpoints located around the world. At the monitor’s most basic, the monitor checks for an error-free response from the web server. Beyond checking for basic website monitoring availability (or uptime monitoring), you can also monitor and trigger alerts for your page load times, minimum page size, content, and status codes. An HTTP monitor is a “basic” check. Learn the difference between basic checks and real browser checks.

Please note that an HTTP monitor only downloads the HTML content of a page. If you want to monitor all elements of a page (including stylesheets, scripts and images) we recommend using a Full Page Check.

Error conditions

You have several conditions you can check and trigger alerts for on your web page. From the Error conditions tab, you can set the page’s load time expectations, expected minimum page size, and set up content matching.

Please refer to the knowledge base article Error conditions for more detail and see the following links for detail on each category of error conditions:

Page availability

Page content

Page load time

Advanced HTTP settings

With the basic HTTP monitor, you can expand the check by declaring a user agent, use basic authentication, and define HTTP Requests on the Advanced tab.

User agent

Do you want to test your web page with specific browsers? Using the User Agent settings you can choose between 15 different commonly used browsers or you can create a custom agent. Please note that this only sends the chosen User Agent along with the request. As such, we do not actually monitor the site in a browser. If you want to monitor a single page in a real browser, please use a Full Page Check.

Authenticate Users

If your page requires user authentication, you can provide a username and password to verify that your authentication processes work correctly. Learn how Uptrends uses encryption to keep your authentication information safe.

Custom HTTP requests

The basic HTTP monitor uses a “get” header, but you can test the post headers as well. You can also create and test your own custom HTTP request headers.

Note: The HTTP monitor type will only download the HTML content of a page. It does not include any images, scripts, or interactive elements that the page may contain. If you need to check the complete content of a web page, we suggest you consider the Full Page Check monitor type.
