Website Monitoring

Website monitors request a URL every 30 seconds from multiple regions and alert you when the site is unavailable, responds slowly, or returns unexpected content. Each check can assert on the status code, response time, body and headers.

Just like with other monitors, when a website monitor detects a problem, you can collaborate with your team to resolve the incident and optionally update your status page.

Monitor is successful if

A website monitor succeeds when all configured conditions are met.
You can define one or more of the following assertions:

Status code: e.g. response is 200 OK
Response time: e.g. under 2 seconds
Body contains: e.g. “Welcome to our site”

If any of these conditions fail, the monitor will be marked as down and alerts will be triggered according to your alert settings.
