Choosing a monitor type
A short guide to help you pick the right monitor type for whatever you need to watch.
HTTP / website monitor
Checks that a URL responds with the right status, within your timeout and fast enough.
SSL certificate monitor
Warns before your site's SSL certificate expires and detects invalid certificates and issuer changes.
Domain / registration monitor
Warns before your domain registration lapses and reads registrar, nameservers and expiry via RDAP.
DNS monitor
Watches your DNS records against expected values and can alarm when the records change.
API / JSON monitor
Checks an API call: method, status, response time and specific values in the JSON response.
TCP / port monitor
Checks that a raw TCP connection can be opened to a given host and port.
Setting up a heartbeat monitor
A dead-man's switch for cron jobs and backups – it alarms when the expected ping fails to arrive.
Synthetic flow monitor
Runs a scripted flow in a real browser – ideal for login, cart and checkout journeys.
