Web checks

Does the site open?And does it show what it should?

An HTTP monitor fetches the page like a visitor would: status code, response time, redirects, certificate validity and page content. Any condition you set that does not hold marks that cycle as a failure.

What happens in each check

With nothing installed on your server.

  1. A request from several regions

    The same cycle runs from the vantage points you picked, not just one.

  2. Conditions evaluated

    Status code, response-time ceiling and content assertions are applied to that response.

  3. Result and evidence stored

    Each region's result is kept separately, and on failure the technical evidence of that moment is preserved.

Conditions you can set

All of them phrased as "when is this a failure".

Status code

You name the successful codes; anything else fails.

Text on the page

Present, absent, exactly equal, or matching a pattern.

Response-time ceiling

A slower response fails the cycle — separate from the slowdown alert, which only raises a performance incident.

Certificates and redirects

Redirect following and certificate verification can each be turned off, for services with internal certificates.

Several regions, one verdict

When one region reaches the site and another does not, the rule must be explicit.

Failure in any region

The most cautious setting: one vantage point failing is enough to call the cycle down.

Failure in half or more

The middle ground; a single network path does not declare the whole service down.

Failure in every region

The strictest setting, for services whose regional reachability is inherently unstable.

Where this stops

One request, not a scenario

A monitor fetches one address; filling in forms or multi-step journeys are not supported.

No JavaScript execution

The page is fetched as an HTTP request, not rendered in a browser, so content built only by JS is not seen.

Advanced matching starts at Starter

The free plan has "contains"; exact match, patterns, custom headers and bodies come with the Starter plan.
